2.4Operation and Functionality Test
AC Mode
The UPS delivers power to the loads derived from the utility and maintains proper battery charge. It also regulates the output voltage to within a narrow range and serves to isolate the load from surges and electrical noise brought by the utility wiring.
On Battery Mode
The UPS operates on battery when the line voltage or frequency has fallen out- side the limits. Users are alerted to this mode of operation by visual indicators. The UPS provides power to the load from the battery and through its inverter and the output voltage and frequency of the UPS are regulated within a narrow band.
