Unipower Telecom Introduces New INV2500 Inverter

November 09, 2000 by Jeff Shepard

Unipower Telecom (Coral Springs, FL) has introduced the INV2500 inverter, which achieves 7.0VA per cubic inch. The INV2500 is capable of producing 115Vac at 2,500VA in a 3.5" x 8.5" x 12" case. It can be configured for 19" and 23" rack-mount in either a single 2,500VA output or a dual 5,000VA solution.

Unipower Telecom claims that the INV2500 produces a near-perfect 60Hz sinusoidal waveform from a 48V source. Frequency stability for the product is plus or minus 0.1 percent, while total harmonic distortion is less than 2.0 percent and efficiency is 90 percent. The input voltage range is 42V to 56V, and the unit is fully isolated from the battery. Multiple INV2500 units can be paralleled for higher output power or for N+1 redundant applications.

The INV2500 solid-state inverters employ MOSFET and IGBT power switches together with high-frequency, pulse-width modulation techniques to synthesize a precision-regulated sinusoidal output. The fully isolated output can power any load from a +90 to a -90 degree phase angle. 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. The inverter has a synchronization feature, should the bus be live, and facilitates quick disconnection in the event of an internal fault. The inverters have a high-surge capability for starting into inductive loads like motors, but the quick-trip output breaker trips if power tries to flow back into a faulted inverter.

Unipower Telecom believes that the INV2500 is ideal for UPS backup applications, telecom sites, electric utility sub-stations, fuel cells and solar-panel applications.

Pricing for the INV2500 starts at $2,795 in OEM quantities. Delivery is stock to six weeks, depending on quantity.
