UPS -  Uninterruptible Power Supply

The continuity of electrical power is an essential requirement for critical load operations .The Uninterruptible Power Supply (UPS) is designed to meet the user‘s need of present computer, server and the equipment of office automation that make the UPS more compact and less noisy.

To choose the UPS as your equipment protector is a wise investment because it supplies reliable, pure and stable power at affordable price.

The UPS system is composed of input breakers, input filter & protection network, rectifier, battery bank, inverter, static switch, bypass breaker, isolation transformer and output filter. Under normal AC mode, energy from the AC source is converted to DC power and supplied to the inverter to charge the batteries to its full capacity all the time, ready to support the output load in case of AC source failure.

Although the principle and operation of a UPS seems simple and straightforward, the requirement for a reliable and intelligent UPS makes the design and manufacturing of a high power UPS one requiring advanced technology, intelligence, experience and most important, consideration of the user interface. Many years have been spent in designing the most rugged, intelligent and reliable UPS for the market, and a safe and convenient UPS for the user.

Choosing the best and most suitable UPS for a given application can be easy or difficult, depending on the client’s knowledge of key parameters. The most obvious specification, output power, depends on the size of the load. Often, an allowance of 50% more power is added to the present load requirement, both for tolerance and for future expansion. 

Another important issue is reliability. The prime aim of a UPS is to protect your load. Therefore, the UPS should be much more reliable than the AC source. An unreliable UPS may suffer the problem of frequent break down, even more frequent than AC failure, and the cost of repair may become more than the cost of the unit itself.
