This uninterruptible power supplies device has the capability of converting from 12volts D.C to 220volts alternating current at the frequency of 50Hz with the help of a step-up transformer. The main importance of this device is its ability to ensure absolute continuity of power to the computerized control system thereby protecting a critical equipment from electrical supply failure. Ups system achieve this by rectifying the mains supply, using the direct current to charge the standby battery and to produce a “clean†alternating current by passing through an inverter and filter system. The output produced is free of sags of services in the line voltage, frequency variation, spikes and transients.
