DESCRIPTION

Unipower Telecom's INV2500-HS Series are 2500 volt-ampere, sine wave, hot-swap inverter modules which are available with a compatible, two-unit 19-inch shelf. The shelf is 2U high (3.5 inches). The units operate off a 48VDC (42-56V range) input and produce either 115VAC output at 22A RMS or 230VAC at 11A RMS. Two units in the shelf produce 115VAC at 44A or 230VAC at 22A. The low distortion 50 or 60Hz sine wave is produced using MOSFET and IGBT power semiconductors with advanced, high-frequency, pulse-width modulation techniques which achieve 90% efficiency and 7.2VA per cubic inch power density.

The units can be paralleled for higher output power for for N+1 redundant applications. When operated in the shelf they are automatically paralleled. They are fully isolated from the telecom battery.

An input circuit breaker turns the inverter on and protects the battery from input faults. An output breaker connects the inverter to the load bus (after synchronization if the bus is live) and quickly disconnects the inverter in the event of an internal fault. The inverter has high surge capability (up to 300%) for starting loads such as motors, but the output breaker quickly trips if power attempts to flow back into a faulted inverter.

Front panel LEDs indicate inverter status, and Form C relay alarm contacts are available on the back. The units are self-cooled by internal fans.
