Rack-mount inverter is protected in and out

Unipower Telecom's new INV5000 telecomms inverter produces 230V AC RMS at 5kVA in a 2U-high (88mm) shelf, which is mountable in either a 19 or 23in equipment rack.

Unipower Telecom's new INV5000 telecomms inverter produces 230V AC RMS at 5kVA in a 2U-high (88mm) shelf, which is mountable in either a 19 or 23in equipment rack.

The output is a near-perfect 50Hz sinusoidal waveform with +/-0.1% frequency stability and less than 2% total harmonic distortion.

The input voltage is 48V DC nominal, with a range of 42 to 56V DC and the unit is fully isolated from the battery.

Input circuit breakers turn the inverter on and protect the battery from input faults.

Output breakers connect the inverter to the load bus and quickly disconnect in the event of an internal fault.

The inverter also has a synchronisation feature for connection to a live AC bus.

It has a high surge capability for starting into inductive loads like motors, but the quick-trip output breakers trip if power tries 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 inverter is self-cooled by internal ball bearing fans.

The inverter employs mosfet and IGBT power switches together with advanced high frequency, pulse-width modulation techniques to synthesise a precision, regulated sinusoidal output.

The fully isolated output can power any load from +90 to -90deg phase angle.

The INV5000 is ideally suited for use in telecom sites, electric utility substations, fuel cells and solar panel applications.
