MODES OF OPERATION
The UPS module shall be designed to operate as a double conversion, on-line reverse transfer
system in the following modes.
A. Normal: The inverter shall continuously supply power to the critical load. The PFC rectifier shall
derive power from the utility AC source and supply DC power to the inverter while
simultaneously float charging the battery.
B. Emergency: Upon failure of the utility AC power source, the critical load shall be supplied by
the inverter, which, without any interruption, shall obtain its power from the battery.
C. Recharge: Upon restoration of the utility AC power source (prior to complete battery discharge),
the PFC rectifier shall power the inverter and simultaneously recharge the battery.
D. Bypass Mode: The static bypass transfer switch shall be used to transfer the load to the
bypass without interruption to the critical power load. This shall be accomplished by turning the
inverter off. Automatic re-transfer or forward transfer of the load shall be accomplished by
turning the inverter on.
