UPS: Buying Guide

UPS is a device that provides protection from power problems and provides emergency power in the time of main power failure for online server backups or online data backups. Different kinds and power ranges of UPS are available in the market. Purchase the one which fulfills your needs adequately.

- Standby UPS
These kinds of uninterrupted power supplies provide protection to electrical equipments from power surges. The standby UPS is commonly available in low power range, say 400 VA to 700 VA, therefore suitable for domestic applications. It is one of the cheapest designs of UPS, present in the market.

- Line-interactive UPS
Line-interactive systems are used to get respite from power problems like transient voltage and power noises. These kinds of power supplies are commonly available in high power range of, say 600 VA to 1000 VA and are suitable for performing commercial applications.

While purchasing uninterrupted power supplies, consider following factors:

· Capacity
The capacity of an UPS is measured in VA (voltage ampere). Make sure to purchase a VA of UPS which can provide emergency lights to large number of electrical equipments. The ideal UPS is the one which provides protection more than is required.

· Run time
Run time is another factor which requires equal consideration while buying UPS. A UPS that has a low power range has low runtime, while high power range has high time. So, determine your power needs, and purchase UPS accordingly.

· Insurance
Consider purchasing a UPS which is backed up by an insurance guarantee scheme. Some other factors which need to be looked upon are output frequency regulation and the cost for replacement batteries, etc. So, consider all these and many other factors before buying an uninterruptible power supply.

Pros:

· Provides adequate protection from various kinds of power problems.
· Saves electrical equipments from getting physically damaged.

Cons:
· An uninterruptible power supply has low backup time.
