1. Tips on buying a UPS for personal use
Here are some tips on buying a UPS (Uninterrupted Power Supply) for your
personal use. You will find it helpful to in making a decision.
1) Connect only critical loads to your UPS. Only those that need protection, as
certain type of malfunctions in some users can cause a total output shutdown
2) Factor in an increase in load capacity to allow for future expansion
3) Consider if it is worthwhile to opt for the next UPS size to increase back-up
time. Check the Rated Backup Time; it generally refers to full load, increasing
almost three fold at half load.
4) Factor in the temperature. Battery life of your UPS decreases by 50% with
every 10 degree rise in temperature
5) Opt for Ups systems that allow extended battery options. They have the
options of increasing power by adding parallel units when you feel the need to
step up power
6) If there seems to be no obvious plus point in buying a certain UPS, don’t pay
more to buy it. A big price tag is not indicative of its performance or reliability
7) Check the warranty and guarantee of your UPS. The amounts specified
generally cover only hardware, not items like loss of data or discontinuity of
service
8) Watch out for smart marketing terms and don’t be mislead by them. An
‘Automatic Self test’ UPS does not mean it checks the battery as well. So while
you are under the impression that a positive test of your UPS is keeping you
safe from a breakdown, your battery might be on the verge of a shutdown. An
‘online’ must be Double Conversion and able to regulate output frequency.
9) Ensure the after sales service of the manufacturer is good. Check the repute
and standing of the company, their network, service charges etc.
10) Always buy a UPS from a reputed manufacturer. The manufacturer should
have been in the business for at least 10 years with a good track record and
reputation of trust. In India, one of the best manufacturers is V Guard
Industries.
11) Lastly, if you are in doubt about which UPS to buy, talk to a consultant. He
will advice you on the best option for you and ensures that you are protected
from any malfunctions due to any inadequacy of your equipment in protecting
your hardware.
