If you are thinking of buying a new UPS for your computer/LCD monitor, you should have a look at the APC BR1500G BACK-UPS Pro. There are cheaper 500VA models for sure, but this one packs 1500VA/865W of power and works at an input voltage of around 120V. If you want your UPS connected systems to work for a longer time during power cuts, you should consider a high-power consumer UPS model like this one.
This model gives approximately 40 minutes of back-up power when the following are connected to it/being used: Desktop computer + 2 x LCD monitors + Modem/Router + Cordless phone + External NAS storage unit. Of course, if you just use one computer and monitor, the back-up time will be even higher. Isn’t that impressive when compared to the cheaper models that give 10-15 minutes of backup?
The APC BR1500G BACK-UPS Pro model comes with 10 power outlets out of which five are UPS supply + Surge protector. If you connect the power outlets according to the suggestions (each outlet is optimized to connect a particular type of device), the backup power realization will be even more. Small techniques like lowering the monitor brightness during a power cut, can extend the back-up time. This model is expandable, and hence buying an BR24BPG external battery pack and chaining it with this model can double the backup power/time.
One interesting feature of this model is its capacity to automatically switch off a PC connected to it (a separate USB cable connection is required) after a certain minimum time has elapsed, during power cuts. This could be useful to people who leave their computer ON while they are not around. Another interesting feature of this model is its ‘mute’ functionality. Who wants the UPS to keep shouting (beeping) during low-battery scenario? If its quiet, we can do our work peacefully at least for the time it is online. There is an easy-to-access mute button conveniently placed on the front side of the UPS.
UPS batteries require replacement every three/four years. The battery in this model can be replaced by customers themselves. There is a useful LCD display that displays the current load (wattage consumption), voltage etc so that you know how much power is being used by the UPS at any point of time. Based on that, you can add or remove a couple of devices from the UPS. The LCD screen also shows the amount of time/back-up power left (under current load).
This unit self tests itself every time it’s switched on or on a weekly basis. So, there is no need to unplug the UPS from the power supply just to test if it is working. Also, unplugging the UPS from the AC supply leaves your system ungrounded and hence it is not a recommended practice to test the working of any UPS. Avoid doing it. Also, don’t plug-in devices like fans that require smooth sinusoidal current.
