Uninterruptible Power Supply (UPS) is an electronic device that offers battery backup service to computers or other devices during power interruptions. They therefore allow your devices to shut down safely in case of power outages. Another function of UPS is to protect your device from over-voltages and brow-outs. Choosing UPS system that suits your need can improve performance of your devices.
You need to put into consideration the power output of the UPS system as compared to your devices power consumption. Buy a backup system that can support all devices including wireless routers that demand much power. Furthermore, choose a backup system that can alert you about power shortcomings such as over-voltages, blowouts or power insufficiencies. That said, you might need to invest a little more to get the best UPS system.
The UPS run time is another feature that determines the suitability of a backup device. This is an estimation of how long a power backup device can supply power. Some low cost UPS systems may offer lesser duration of use depending on what devices are used with them. Always choose a UPS system that has a longer run time and the one that make an alert in case power goes out to prevent possible damage to the computer.Different UPS have different methods of detecting when battery backup support should be started. This is based on the point that the UPS systems are categorized based on their power tolerance levels. The most basic backup system is the standby mode type that only switches to battery after the power supply voltage drops below a certain level. This backup system is the most commonly used and is considered relatively cheaper.
It is also critical to consider how the UPS system decides when to switch to devices battery power. The backup systems are categorized into three based on this factor. There is the standby mode UPS system which detect when power supply is below a certain level. It is the cheapest and most available type of power backup.
There is also an on-line interactive type that has an inbuilt transformer that controls the AC voltage when too high or too low. This ensures that the device battery will be used only when incoming power supply drops too low. Too much power interruptions can damage your battery as the UPS keeps on switching to battery. This will reduce your battery usage lifetime and the battery capacity.
You may also find another UPS system known as the dual conversion type that is considered the most effected power backup. The system is packed with an inverter that convert power supply to DC and later to AC after ensuring no power oversupply is noted. The process works out without notable transfer time. This efficiency eliminates the incoming line noise or surge because the inverter corrects any underlying problem. Thus over voltages, under voltages and related issues cannot damage your battery or the computer.
It is also necessary to consider the power output quality. Some UPS system cannot output the actual electric sine wave power. A standby mode backup system will only convert power to square wave which is of poor quality. Some devices can only work with the sine wave AC power such as wireless routers. This might damage the devices when run time decreases and device shuts down. To cater for such possible risks, you can consider buying a dual compression UPS system. Such systems are however costly but are worth trying.
You would also have to consider the type of power outlet that the UPS system has. A number of backup systems may not offer protection against power outages or blowouts. Some may have Ethernet and other cable ports but ensure all ports offer protection from spikes and power surges.
