Types of Uninterruptible Power Supply Systems Based on Working Mechanism

The Uninterruptible Power Supply (UPS) device offers extended protection against several power troubles. Basically, there are three types of UPS systems-Standby, On-line and Line-Interactive UPS Systems.

In the Standby sine wave UPS models, power is supplied by means of surge and noise control circuitry and then to your equipment. In the intervening time, a battery charger keeps an internal battery fully loaded and all set for use. When there is an outage, temporary reduction in electrical power or voltage fluctuation, the inverter converts battery output into a replicated sine wave output. When the electrical supply returns, the device itself switches back to the battery power and the battery is again topped off.

The same way as in the Standby systems, the power in the Line-Interactive systems is also provided through surge and noise suppression circuitry. Later on the integrated line conditioning circuitry monitors the irregular voltage levels to the normal levels, and supplies simulated power on to your apparatus, without exploiting the battery power. The internal battery remains fully charged by a battery charger. When the power goes off, inverter transforms the battery power to sine wave power and when the power is back, the inverter switches off and the battery is recharged.

In the On-Line models, the maximum level of power protection is ensured. The disrupted power is flawlessly rebuilt by the inverter that is "on-line" all the time. This implies that the transfer switching time is next to zero.

If the power outage in your area is very uncommon, then you can also get the mini CFL UPS for your home that ensures that the lights are on at your place when the power outage is there.
