Scope
This specification describes the requirements for an On-Line Uninterruptible Power
Supply (UPS). The UPS will supply a computer grade AC output sinewave which is
unaffected by the quality of the AC input. The input voltage shall be single phase with
the output voltage being single phase.
2.0
General Operation
Under normal operating conditions, the UPS's rectifier converts alternating current (AC
power) to direct current (DC power), which is required for the system's inverter and
battery charger. The charger supplies regulated DC power to keep the batteries
constantly charged. The inverter uses pulse width modulation (PWM) that fully utilizes
the characteristics of insulated-gate bipolar transistors (IGBT) to convert DC power to
regulated AC power. Therefore there is a constant supply of power. The batteries will
instantaneously supply the inverter DC power should an AC power line failure occur.
2.1
Performance Standards
The UPS shall be designed with the applicable sections of UL, CSA, NEMA PE-1, and
IEEE-587(ANSI C62.41). The UPS shall have UL 1778 listing and is CUL certified..
3.0
General
3.1
Materials
All materials used are of new manufacture using the latest technology and should not
have been in prior service except for specified factory testing. IGBT's (insulated-gate
bipolar transistors) are used exclusively in inverter and chopper sections.
3.2
3.3
Components
All functioning components are solid state with no moving parts.
Installation
The installation of the UPS must comply with the UPS manufacturer's recommendations
that will be supplied before delivery of the UPS. Local electrical codes and the National
Electric Code must be complied with. All wiring must comply exactly with what is
specified.
3.4
Assembly
The UPS shall be delivered fully assembled and be fully functional.

4.0
System Theory and Operation
4.1 Theory
AC input from the utility system is converted into DC power by a diode bridge rectifier
and stepped up by the chopper. The stepped up DC power is then converted to AC power
by the inverter. The output voltage waveform of the inverter will be the pulse voltage

Bypass
If the UPS unit is overloaded or develops an internal fault, the power is automatically
switched from the unit's main circuit to the bypass circuit mode. The UPS equipment
load will be supplied by utility power through the bypass circuit. This changeover occurs
in less than 4 milliseconds. The switching period is not long enough to cause
interruptions to occur in your UPS equipment load.

Remote Monitoring
The UPS contains a communication slot this allows the operator to field install an
optional RemotEye II card. The RemotEye II card shall allow the UPS to communicate
via Ethernet SNMP, connected directly to the Local Area Network. SNMP/ Web based
monitoring – Toshiba UPS system provides comprehensive monitoring of the UPS
operation. The optional RemotEye II features an HTTP (web-based) interface for
Toshiba UPS. This allows easy access to the Toshiba UPS information from any
PC/Network with a web browser.
12.2
Environmental Monitoring Device (EMD)
The EMD is an environmental monitoring device that provides remote monitoring of
temperature, humidity and other environmental conditions via standard web browser or
network management systems. The EMD provides automated events notification when
temperature, humidity or user defined dry contacts is out of configured tolerance.
