Schaefer Pure Sine Wave Inverter Packs 3KVA Into 1U Rackmount Design

Schaefer, Inc. announced that its family of pure sine wave inverter products now boast what is described as the only 3KVA product in the market that is packaged in a 1U rackmount design. The pure sine wave output of the AEP-A3000R series is said to offer benefits over modified or quasi-sine wave units by delivering "clean" output power for powering sensitive loads and for improving ac equipment performance.

The AEP-A3000R series is available in three standard input configurations of 12, 24 and 48Vdc. Outputs are available in 115 or 230Vac (50/60Hz) versions, which are regulated to ±3% or better. A built-in, 4-6ms automatic bypass switch allows for redundant operation from utility power if the dc supply drops out.

All models in the AEP-A3000R series feature comprehensive circuit and overload protection with easy to read, user-friendly digital displays and alarms to indicate low input voltage, short circuit, input overvoltage, over temperature, overload and low battery. The display also indicates voltage, amperage, power and temperature. Efficiency is 84 – 90%, depending upon the model selected. The extended operating temperature of -30 to +50°C allows for installation in extreme environments. EMI is minimized for reduced impact on other sensitive equipment.

The 1U, rackmount design is rugged and suitable for industrial, utility, satellite, military, computer, communications, emergency vehicle, marine, and general backup power applications. The slim size of 16 x 19 x 1.73" fits easily into 1U racks.
