1.1 SUMMARY
A. This specification describes the operation and functionality of a continuous duty, single-
phase, solid-state, static Uninterruptible Power System (UPS) hereafter referred to as
the UPS.
B. The UPS utilizes double conversion online topology designed to protect electronic
equipment by supplying reliable, network-grade power featuring extremely tight
voltage and frequency regulation. The UPS also features internal bypass and input
power factor correction.
C. The primary sections of the UPS are: input disconnect and filter stage, input PFC power
stage, energy storage stage (DC bus capacitor bank), output power stage (inverter),
bypass and a battery charger. The control of power module and fault detection logic is
microcontroller based. Input disconnect and filter stage contains input backfeed relay
(in models with a input wire plug), input filter, transient suppression, battery select
transfer relays. Input PFC power stage contains non-isolated power factor correcting
AC/DC converters. This converter is capable of full power operation in very wide input
voltage range
DC bus capacitor handling seamless transitions from battery to line and vice versa as
well as the low and high frequency power stages ripple. The inverter stage operates
directly from the DC bus and produces an AC output voltage of
200/208/220/230/240VAC output. The output of UPS is either connected through a
bypass relay to the inverter or to the input filtered line. UPS contains a battery charger,
which operates from the DC bus
D. The UPS batteries are modular, hot-swappable, user-replaceable.
E. In addition, this specification describes the performance, functionality, and design of
the UPS Service Bypass Panel, hereafter referred to as the SBP, the external Battery
Systems, and connectivity solutions.
F. The UPS and associat ed equipment shall operate in conjunction with a primary power
supply and an output distribution system to provide quality uninterrupted power for
mission critical, electronic equipment load.
or from a nominal DC battery voltage. The energy storage stage is a split
.
G. All programming and miscellaneous components for a fully operational system as
described in this specification shall be available as part of the UPS.

1.3 MODES OF OPERATION
CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM
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. By pass: 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.
