Comet 40-150kVA
Figure 1-3, and 1-4 show single-line diagrams of a typical UPS system installation. During normal operation, utility power (Main Input) is supplied to the UPS Rectifier where it is converted to DC voltage. The Inverter converts the DC voltage from the Rectifier to three-phase regulated AC voltage, which supplies the critical load. During power failure conditions, the Inverter is supplied by the stored energy in the batteries, and the load is powered continuously with no disruption.
