CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM
A. Online: The input PFC power stage and the output power stage (inverter) shall operate
in an on-line manner to continuously regulate power to the critical load. The input PFC
stage shall be capable of full battery recharge while simultaneously providing regulated
power to the load for all line and load conditions within the range of the UPS
specifications.
B. On Battery: Upon failure of the AC input source, the critical load shall continue being
supplied by the output power stage (inverter), which shall derive its power from the
battery system. There shall be no interruption in power to the critical load during both
transfers to battery operation and retransfers from battery to online operation.
C. Bypass: The bypass mode shall be used to provide transfer of critical load from the
inverter output to the primary power source. This transfer, along with its retransfer,
shall take place with no power interruption to the critical load. In the event of an
emergency, this transfer shall be an automatic function.
D. External Service Bypass Panel (SBP): The maintenance service bypass panel shall
provide power to the critical load from the bypass power source during times where
maintenance or service of the UPS is required so that removal of the UPS is desired.
The SBP shall provide a mechanical means of complete isolation of the UPS from the
electrical wiring of the installation. The SBP shall be constructed in a free-standing,
rack mounted or wall-mounted NEMA 1 enclosure unless otherwise stated in this
specification. It shall be designed for single phase input with a “ no break” transfer
between bypass and UPS power.
