UNINTERRUPTIBLE POWER SUPPLY
PART 1 - GENERAL
1.1
SUMMARY
A.
1.2
This specification describes a three-phase continuous duty, on-line, double
conversion, solid-state uninterruptible power system, hereafter referred to as the
30KVA UPS with a minimum battery backup time of 9 minutes. The UPS shall
operate in conjunction with the existing building electrical system to provide
power conditioning, back-up and distribution for the lime slaker electrical loads.
The UPS shall consist of the UPS module, batteries, or other DC storage
systems, and accessory cabinets for transformers, maintenance bypass, and
distribution applications, and other features as described in this specification.
The UPS maximum dimensions shall be 42 inches by 30 inches.
UPS SYSTEM DESCRIPTION
A.
B.
July 2015
UPS System Components: The UPS system shall consist of the following main
components:
1.
UPS module containing Rectifiers, Inverters, Battery Chargers, Static
Bypass, and associated Control and Monitor Panel.
2.
Line-and-Match and/or sidecar-type accessory cabinets for transformer,
maintenance bypass, parallel tie and distribution applications. Specific
accessory availability depends on UPS model.
UPS Module Modes of Operation: The UPS Module shall operate as an on-line,
fully automatic system in the following modes:
1.
Normal: Utilizing commercial AC power, the lime slaker loads shall be
continuously supplied by the Inverter. The Inverter shall power the load
while regulating both voltage and frequency. The Rectifier shall derive
power from the commercial AC source and shall supply DC power to the
Inverter. Simultaneously, the Battery Charger shall charge the battery.
2.
Battery: Upon failure of the commercial AC power, the critical load shall
continue to be supplied by the Inverter, which shall obtain power from the
batteries without any operator intervention. There shall be no interruption
to the critical load upon failure or restoration of the commercial AC
source. The 93PM UPS shall be capable of operating with 480VDC
battery systems.
3.
Recharge: Upon restoration of the AC source, the Charger shall recharge
the batteries and simultaneously the Rectifier shall provide power to the
Inverter. This shall be an automatic function and shall cause no
interruption to the critical load.
4.
Bypass: If the UPS module must be taken out of the Normal mode for
overload, load fault, or internal failures, the static bypass switch shall
automatically transfer the critical load to the commercial AC power.
Return from Bypass mode to Normal mode of operation shall be
Uninterruptible Power Supply
Collier County
SCRWTP Lime Slaker Replacement
16611-2
automatic. No-break transfer to and from Bypass mode shall be capable
of being initiated manually from the front panel.
5.
1.3
1.4
Energy Saver: The UPS shall continuously monitor the voltage and
frequency of the bypass source. When the source parameters are within
acceptable limits, the UPS will utilize a minimal/optimal combination of its
internal subsystems to ensure acceptable power is always delivered to
the critical load, at a system efficiency of up to 99.1%. The Energy Saver
System shall be enabled by the user, and shall be adjustable. It shall
incorporate a “High Alert Mode” to automatically (without user
intervention) provide maximum power conditioning any time bypass
source variation levels exceed preset, adjustable limits. When Energy
Saver System is utilized, the UPS shall attenuate ANSI C62.41-type line
transients to within IEC and ITIC limits.

status changes and commands, all timed to the 1/1000th second for
tracking and analysis.
5.
Statistics tab: Numerically and graphically displays the estimated savings
afforded by ESS operation over time.
6.
Settings tab: shall provide button access to user adjustable settings such
as, but not limited to: date/time, building alarm designations,
communications parameter setup, UPS name, user passwords, and
display language.
Control Panel Lamp Indicators: The UPS control panel shall provide the
following monitoring functions with indicator (icon) LED’s:
1.
NORMAL: This green LED shall indicate that the commercial AC utility or
generator source is supplying power to the rectifier and the inverter is
supporting the critical load.
2.
BYPASS: This amber LED shall indicate that the UPS has transferred
the load to the bypass circuit.
3.
BATTERY: This amber LED shall indicate that the commercial AC utility
or generator source has failed and the battery is supplying power to the
inverter, which is supporting the load.
4.
ALARM: This red LED and the accompanying audible alarm horn, shall
indicate that the UPS detects an alarm condition, outlined in detail in the
Logs tab from the home screen and in the operator’s manual.
Interface panel: The UPS shall be equipped with an interface panel, located
behind a protective cover, which provides the following signals and
communication features in a Class 2 environment:
1.
Alarm contact: A dry contact for annunciating a summary alarm shall be
provided for customer use. This contact shall be Form “C” capable of
supplying both N/O and N/C contacts. Contact ratings shall be 5A max at
a voltage not to exceed 28VDC or 277VAC.
