Unipower Europe Introduces New INV5000 Inverter
Unipower Europe (UK) introduced its new INV5000 telecommunications inverter, which produces 230Vac RMS at 5kVA in a 2U-high (88mm) shelf, and is mountable in either a 19in or 23in equipment rack.
The output is a near-perfect 50Hz sinusoidal waveform with +/-0.1 percent frequency stability and less than two percent total harmonic distortion. The input voltage is 48Vdc nominal, with a range of 42Vdc to 56Vdc 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 synchronization feature for connection to a live ac bus.
It has a high surge capability for starting inductive loads like motors, but the quick-trip output breakers trip if power tries to flow back into a faulted inverter. The inverter employs MOSFET and IGBT power switches, together with advanced high-frequency, pulse-width modulation techniques to synthesize a precision, regulated, sinusoidal output.
The INV5000 is suited for use in telecom sites, electric-utility substations, fuel cells and solar-panel applications.
