2500VA SINEWAVE INVERTER IS

HOT-SWAP AND ONLY 2U HIGH

Coral Springs, Florida- UNIPOWER Telecom's new INV2500-HS telecom inverter is a hot-swap inverter producing 115VAC at 22 amperes RMS to give 2500 volt-amperes output.The unit has the best power density in the industry with its 2U (3.5-inch) high by 8.5-inch wide by 12-inch deep package. The companion 2U hot-swap shelf allows for two 2500 VA inverters to be operated in redundant, 1+1 mode or non-redundant at 5000 VA output. Multiple shelves can also be paralleled for higher power applications.

The INV2500-HS produces a near-perfect 60Hz sinusoidal output waveform with ±0.1% frequency stability. Total harmonic distortion is less than 2% and efficiency is 90%. The 48VDC nominal input has a 42 to 56VDC range, and the unit is fully isolated from the battery. An input circuit breaker turns the inverter on and protects the battery from input faults.

The inverter has a 300% surge capability for starting into inductive loads such as motors, but the output breaker quickly trips if power tries to flow back into a faulted inverter. The output can power any load from +90 to -90 degrees phase angle. The INV2500-HS is self-cooled by two internal fans. Front panel LEDs indicate inverter status and Form C alarm contacts are available on the back of the unit.
