H. Input / Output EMI / RFI Filters 2.3 System Operation The UPS shall operate as an on-line, fully automatic system in the following modes: A. NORMAL - Incoming AC power is boosted using a chopper circuit, and converted into DC power. The DC power is then used to charge the battery bank while at the same time providing clean, DC power to the inverter circuitry. The inverter converts DC power to regulated AC power which feeds the load. B. EMERGENCY - Upon failure

4.0 FUNCTIONAL DESCRIPTION A. Converter / Charger / DC Chopper DESCRIPTION - The converter/charger shall consist of a solid-state three phase rectifier, DC to DC converter (chopper), output filter, and transient suppresser network to regulate and maintain DC power to the inverter. 1) TRANSIENT SUPPRESSER - The incoming AC utility shall first be connected to a molded case circuit breaker as a means of disconnecting power to the UPS. Power shall flow through a surge absorber to pre
