steady voltage waveform. The inverter switching speed shall be fast enough to limit audible noise to 60 dBA at 3 feet (measured on ‘A’ scale).

2)Optional ISOLATION TRANSFORMER - The inverter network shall incorporate a shielded isolation transformer to provide complete isolation of the load from utility AC, as well as providing attenuation for high frequency noise common mode). Additionally, the transformer shall have a set of windings to condition the internal static bypass line.

3)OVERCURRENT PROTECTION - The output circuitry shall be equipped with a Hall Effect Current Transformer to detect and protect the inverter from excessively high currents.

C.Static Bypass Switch

1)TRANSFER - The static bypass switch shall consist of thyristor switches in conjunction with an output contactor to permit manual switching from bypass to UPS and UPS to bypass without power interruption. The UPS shall instantaneously transfer to bypass should a component fail during normal operation (provided the UPS and bypass are in synchronization). Auto-retransfer to UPS after an overload condition shall be completed within one second after the bus has dropped to 100% of nominal.

2)REMOTE RUN/STOP - A set of normally open dry contacts shall be provided to remotely transfer the UPS on-line and off-line. When the UPS is in this mode of operation, the UPS front control panel shall be disabled to provide a secured configuration.

D.Microprocessor Control System

1)DESCRIPTION - The UPS system shall be provided with a highly reliable microprocessor internal control system to perform start-up, transfers, monitoring, and battery recharging. The microprocessor shall provide important information to the user (via a liquid crystal display) with such as system status, fault messages and input and output parameters.

2)LED INDICATORS - The following LED indicators shall be provided on the UPS front panel displays, which mimic power flow through the UPS:

a)AC INPUT (Green Lamp) - Lights when normal AC input power is being supplied to the unit.

b)INVERTER (Green Lamp) - Lights when the UPS unit’s inverter is normal.

c)BATTERY (Green Lamp) - Lights when the batteries are
