UPS Buying Guide
UPS Types
When you’re looking for a UPS, there are several types to choose from. These include standby, online, line-interactive, and data line surge protection. Understanding the differences among these different types will help you make the right choice for your needs. Listed below are some important points to keep in mind when making a purchase.
Standby
When you use a standby UPS, you are protected against power fluctuations. A standard UPS runs on a range of 90V-140V. It switches over to the battery when the voltage is outside this range. In this way, it protects your equipment from power outages for a longer period of time.
A double conversion UPS can also protect sensitive equipment, such as servers and data centers, or medical equipment in intensive care units. These types of UPS are the most expensive options.
The Inverter Active Design: The inverter active design provides improved filtering and reduces switching transients. It also offers two independent power paths for the load.
This design also eliminates a single point of failure for the UPS; even if the inverter fails, AC power will still flow to the output. In addition to these advantages, inverter active UPSs are also inexpensive and offer high reliability. These types of UPSs are also compatible with low-voltage applications.
The Standby UPS provides backup power in the event of power interruptions. A standby UPS has a battery to supply power during an outage. It receives utility power under normal conditions and automatically switches to battery power when necessary.
A standby UPS also safeguards sensitive equipment from surges and other power fluctuations. Some standby UPS types are compact enough for home use, while others are designed for business use.
Standby-Ferro UPS: Another standby UPS type, the Ferro UPS, provides output waveform shaping and limited voltage regulation. However, this type is less efficient and inefficient than other standby UPS types. Because of the low efficiency, it generates a lot of heat and is relatively large compared to other isolation transformers.
A VFD UPS: Another standby UPS type, the VFD UPS, has high efficiency and is cheap. When properly installed, a VFD UPS can provide adequate surge suppression and noise filtration. The only disadvantage of VFD UPSs is that they use the battery during a brownout, which reduces the battery’s life. A VFD UPS is not recommended for sensitive electrical equipment.
While most standby UPS types can protect your equipment from power interruptions, they differ in the features and benefits they offer. Their working principles are very different. The internal design of the topology of a UPS determines how well it operates in different environments.
Online
There are two main types of UPS systems available: online UPS systems and offline UPS systems. Both are capable of switching over to battery power in the event of a power failure.
Online UPS systems can also have failsafe features and self-diagnostic capabilities. This means that even if the hardware fails or the system is overloaded, the load will switch to the mains power without the need for manual intervention.
Offline UPS types use a different technology than Online UPS types. These types of systems provide power to the AC load via an inverter. The inverter in an online UPS is fast and has a battery that feeds the load if the mains fail. They are fast in operation and can save time by avoiding the need to switch power sources manually.
The main difference between standby and online UPS systems is the type of protection they provide. Online UPS systems can isolate equipment from a power outage and protect it against electromagnetic noise and surges.
They are ideal for securing sensitive IT equipment and systems from power problems. Some online UPS systems can supply 500 W or more. They may be necessary for noisy environments or frequent power anomalies, to protect loads of sensitive IT equipment, or to ensure uninterrupted operations in the event of a power failure.
Online UPS systems are great for high-end servers and mission-critical IT equipment. They also offer features like self-diagnostic capabilities and total power condition settings. These systems are typically more expensive than their traditional counterparts but are the best option for securing high-end servers and data center installations. These systems are not suitable for use in homes or small offices.
Online UPS systems also have the advantage of using an eco-mode to protect against energy issues while lowering costs. They may also operate in Line Interactive mode, which allows for a continuous feed from the AC line.
This mode helps the system maintain power stability without compromising performance. A line-interactive UPS system will regulate the output voltage within +-8 to 15% of the nominal level.
Offline UPS systems are less suitable for modern computer loads because their output is unstable. For example, power supplies for routers and servers are power factor corrected.
This is done by using capacitors with reactance. In turn, this creates a voltage lag. The output is then converted to DC and fed to the load. When the AC is restored, the system switches back to battery mode, which can take four to 10 ms.
Line Interactive
The Line Interactive UPS is a great choice for areas with frequent power fluctuations. It can correct minor power fluctuations without dipping into the battery, which prolongs its life.
Line Interactive UPSs are best suited for computer and IT equipment that are sensitive to changes in voltage. For these loads, the higher-end versions of Line Interactive UPSs are recommended.
A line-interactive UPS is different from a standby UPS in that the prime power is fed through a transfer switch and then to the load. It also has an inverter that is always active. The inverter converts incoming AC power into DC to charge the backup battery. Once the prime power fails, the transfer switch opens, allowing the backup battery to charge.
The Line Interactive UPS type uses Automatic Voltage Regulation (AVR) technology to automatically react to fluctuations in the grid power. Because it uses the utility as the first line of power, it can compensate for low and high voltage without affecting the battery.
Line Interactive UPSs are commonly used for consumer electronics such as PCs, gaming systems, home theatre devices, and entry-to-mid-range servers. These units can also be used to provide power during a blackout or a voltage sag.
There are three main types of UPS systems. Each model has different features and configurations.
Data Line Surge Protection
UPS systems protect computers and other electronic equipment when their primary power source is unreliable or has to be shut down. These devices often come with built-in surge suppression, which can help protect your connected load from small hits. However, built-in surge suppression is not a complete solution for transient surges, as they can damage switching and logic control circuits.
Data-line surges can result from a number of sources, including lightning and static charge build-up. These surges can damage network cards and cause system lockup. They may also occur from unshielded twisted-pair and coaxial network interfaces. Data-line surge suppressors can prevent such surges from entering the computer network.
These devices are similar to power strips. They are designed to provide a second level of surge protection and have a battery that allows them to continue providing power to connected equipment.
Most models will provide enough battery capacity to keep multiple devices running for several minutes. Because these devices are not primary surge protectors, it is never a good idea to rely on them solely.
Surge protection works by slicing off voltages above their safe range. These surges can damage your electronics, and some types of surge protection can even fry your entire device. The voltage sags can also occur if there are large motors nearby. Therefore, it is important to protect your sensitive electronic equipment from these surges.
Another important feature of UPS systems is their ability to communicate with other devices. In the case of extended power outages, UPS systems can help in gracefully shut down your system. They may also offer statuses informs, such as an audible alarm or large front-panel LCD. These UPS units can even be connected remotely via an Ethernet network.
Choosing the right power protection for your computer system is important. While most computers are safe and can withstand common power outages, they need protection from power surges. Power surges are powerful and can fry an entire rack of gear. This can result in the loss of data or corrupted systems.
UPS Features
UPS features are the features that allow a UPS to protect your electronics from power failures. These features include Energy-Saving Models, Multifunction LCD Control Panels, and User-Replaceable Batteries. Understanding the different features will help you choose the right UPS for your needs. In addition, consider how long you expect to use a UPS.
Energy-Saving Models
When shopping for a UPS, energy-saving features are an important factor. An energy-saving UPS will generate less waste heat and run more efficiently. This could lead to longer battery life.
The location of the UPS, inverter and associated cooling and ventilation is also a factor. Energy-saving features can reduce the cost of purchasing a new UPS or extend the life of a current unit.
New UPSs typically have a high-efficiency rating, ranging from 92% to 95%. However, older “legacy” models are less efficient and may be as low as 85%. A high-efficiency UPS will produce less heat, and will not require as much air conditioning to maintain its cool environment.
A UPS’s energy efficiency depends on the design of its components. A double-conversion model is an example of an energy-saving UPS, which converts AC to DC, and then back to AC again.
Manufacturers are developing UPS systems with higher efficiency rates than ever before. The size of the UPS is also a factor, as the higher the capacity, the more energy-efficient it will be.
Communication Ports
Communication ports are a key feature in UPSs. They allow you to connect your UPS to other devices, such as your computer. Consumer UPSs usually have two LAN ports.
These allow you to connect your computer to the UPS and automatically save files in the event of a power blackout. You can also get an EPO/ROO port or a USB port for your PC to communicate with your UPS. Many models also have an IP-based management controller, which lets you remotely monitor and control the UPS.
Some models also have built-in filters to prevent power line interference. AEM filters, for instance, can prevent electromagnetic interference, which is harmful to electronic devices.
Surge suppressors can also help protect your devices from power fluctuations by diverting excess voltage away from them. Another important UPS feature is Automatic Voltage Regulation, or AVR, which helps stabilize power fluctuations.
APC UPSs have built-in intelligent power manager software. This software helps you manage your UPS remotely, and integrate it into a larger network. The software supports VMware’s vCenter Server and Microsoft’s SCVMM.
To use Intelligent Power Manager, you’ll need a computer with internet access. Then, you’ll need to connect your UPS to the software via USB or RS232 ports.
Multifunction LCD Control Panel
A Multifunction LCD Control Panel provides quick and easy access to detailed UPS settings. Its LCD screen can display a variety of data, including battery level and power status.
It also shows a block diagram that indicates the UPS’s mode of operation and power conditions. These features make it easier to diagnose power problems before they lead to downtime.
A Multifunction LCD Control Panel allows you to monitor and control the advanced features of your UPS without the use of a computer. It can also display battery capacity and input voltage.
Many models also come with a dimmable LCD backlight so that you can keep an eye on the information without being distracted by bright lights. Some models come with replaceable battery cartridges for added convenience.
Besides its LCD Control Panel, UPSs also offer other useful features. These include active PFC power source compatibility and a battery backup. These UPSs also offer a multifunction LCD Control Panel. These panels have a color LCD that lets you confirm the status of the UPS at a glance and can even be tilted for easy viewing.
User-Replaceable Batteries
If you’re looking to maintain your UPS, you may want to consider using User-Replaceable Batteries (RBCs). These battery packs provide backup power during power outages. They’re available in a variety of sizes and have been specially designed for specific APC UPS models. These batteries are maintenance-free and tested to ensure compatibility with your device.
UPS batteries come in many forms, including user-replaceable and hot-swappable. In fact, many manufacturers offer standard-use, high-current, and cyclic-use batteries.
However, some UPS units don’t work well with these batteries. These types of batteries are commonly used in alarm devices and emergency lights. Some manufacturers sell batteries designed for this purpose, including Panasonic LCR127R2PG1, Fiamm FG20902, and CSB HR 1234W.
The type of UPS battery that you choose will determine the maintenance requirements of your unit. VRLA batteries are the easiest to maintain, but wet-cell batteries are harder to care for. In addition, you need to monitor the temperature to prevent overheating and premature failure of the batteries. The temperature must be at least 50 degrees Fahrenheit or 10 degrees Celsius to prevent damage to the battery.
Lithium Batteries
Lithium batteries are used in UPS systems to store power. They have a range of benefits over traditional lead acid batteries. They have lower sensitivity to temperature variations and are able to withstand spikes in temperature without degradation in cycle life.
However, lithium-ion batteries are notorious for their potential for ‘thermal runaway,’ which can result in combustion. The batteries also have low flammability and no dangerous odor or caustic materials.
Another advantage of lithium batteries is their long life cycle. Unlike lead-acid batteries, which typically last three to five years, lithium-ion batteries can last eight to ten years. This means that you never have to replace your UPS battery again, which could save you a lot of money in operation costs.
Lithium-ion batteries have more safety features than other batteries. They are harder to ignite during transportation, which reduces the risk of fire. In addition, UPSs with lithium-ion batteries feature a battery management system.
This system protects the battery from heat, over-current, and over-charging, and optimizes battery charging on an ongoing basis. In addition to safety, Lithium-ion batteries increase the life of UPS systems.
Extended Runtime
A UPS with Extended Runtime features provides a long battery runtime for your critical equipment. These battery packs may be removable or built-in. They may also be daisy-chained together to achieve extended runtime.
Some models may limit the number of battery extension packs they can support. In such cases, you may want to purchase a continuous-running UPS that supports additional battery packs.
The maximum load that a UPS can tolerate is listed in volt-amperes (VA). UPS manufacturers measure this capacity using a different formula. The formula for watts is equal to volts times amps, times power factor. This information is useful in determining a total load of a UPS and how long it can safely run after a power failure.
Some UPSs come with network management cards, which turn them into managed devices. With these cards, you can monitor the UPS remotely through SNMP, telnet, or SSH. Some network UPS systems even support remote temperature and humidity measurements.
Cooling Fan
UPS cooling fans work to keep the internal components cool. The rectifier and inverter operate in hot conditions, and they can deteriorate more quickly if they are not kept cool. UPS cooling fans are located in strategic locations to keep these components cool. A larger UPS will have more fans than a smaller one.
Some UPS units have several ports for connecting external devices. For example, some have two USB Communication ports that allow you to connect your computer to the UPS and automatically save files if there is a power blackout. Other UPS devices will have separate outlets for AC adapters. Some also feature a ground screw.
Some UPS units will have LED indicators that indicate their battery capacity and voltage. These indicators can help you determine whether your UPS is operating properly. You can also view the status of the UPS with its LCD display.
Remote Power Management
Remote Power Management for UPS is the process of remotely monitoring a UPS and enabling it to manage its functions remotely. This capability allows UPS administrators to control power usage and restart power supply units in the event of a power failure.
Such functionality can minimize downtime and improve the efficiency of network components. Some UPS systems have web interfaces for monitoring power consumption and can be configured to provide real-time data.
Using a management software program, UPS administrators can monitor their UPSs remotely and receive alerts via their computers. Some UPS management software systems also have the option of sending alerts via SMS or to a cell phone.
Other features include remote rebooting and SNMP connectivity. Some UPS units also have battery management systems that can provide detailed information about battery health and charge. Additionally, some systems can be configured to allow remote firmware upgrades.
Opengear’s power management software enables the monitoring of remote power control and UPS systems. It supports a wide range of RPC and UPS devices. It can control the power supply to critical devices such as servers, storage, telephony, and network equipment. It also has the ability to configure servers and networks with service processors.
