UPS Output with Energy Saver System option
1.
The Energy Saver System acts to optimize the internal components of the UPS
power train to maximize system efficiency when the bypass source is within the
following (adjustable) limits: Voltage: +/-10%, and Frequency: +/-3Hz.
2.
Nominal output voltage 208 VAC, 3-phase, 3 wire or 4-wire (or 480V, 3-phase, 3-
wire or 4-wire) plus ground at the output of the Integrated Distribution and
Bypass cabinet. Output wiring configuration is based upon input wiring
configuration for systems without internal transformers.
3.
Steady-state voltage regulation shall be within +/- 10% from nominal output
voltage.
4.
Line synchronization range shall be +/- 3Hz, adjustable to +/- 5Hz.
5.
Frequency regulation shall be +/-3Hz when bypass source is within the limits in
(1) above, and +/- 0.01Hz free running,
6.
Overload current capability (with bypass source within the limits of (1) above)
1000% for 20msec, 600%
for 50 ms
7.
Static transfer time: No break, completed in less than 2ms, including detection
time.
8.
Acoustical noise: Noise generated by the UPS under normal operation shall not
exceed 65dbA at one meter from any operator surface, measured at 25 degrees
C (77 degrees F) and full load.
9.
EMI Suppression: The UPS shall meet FCC rules and regulation 47, part 15, for
Class A devices prior to Feb 16, 2006.
10.
Electrostatic discharge (ESD): The UPS shall meet IEC 801-2 specifications.
The UPS shall withstand a 25 kV pulse without damage and with no disturbance
or adverse effect to the critical load.
11.
Efficiency: The UPS efficiency shall greater than 99%, over the range of 10 to
100% load. (98.5% for 208V units)
G.
UPS in Parallel Configurations:
UPS modules shall be capable of being paralleled to increase system power levels or to
provide redundant power. A total of eight (8) UPS modules shall be capable of parallel
operation, either for capacity or redundant systems. It shall be possible to parallel up to
six (6) UPS modules without a central bypass cabinet. The parallel system shall have
intelligence to automatically recognize the need for capacity and/or redundancy. Parallel
systems shall utilize autonomous UPS power modules that do not rely on any control
interconnections for synchronized operation. The individual modules shall operate in a
peer-to-peer manner to provide automatic load sharing, synchronization, and selective
tripping capabilities. “Master-slave” configurations are not acceptable.
The parallel system shall utilize a communications network to provide system information
and status, such as operating mode and meter data. This network shall provide
individual module information as well as total system information, and individual module
information shall be available from any module’s front panel display. The loss of this
system information network shall not cause the parallel units to transfer to bypass or drop
the critical load.

MECHANICAL DESIGN
A.
Enclosures: The UPS shall be housed in free-standing double front enclosures (safety
shields behind doors) equipped with casters and leveling feet. The enclosures shall be
