Rack-Mount Sine Wave Inverter from Schaefer
Rack-mount sine-wave inverter.
Ashland, MA — Schaefer, Inc.'s family of pure sine wave inverter products now has the only 3kVA product in the market that is packaged in a slim, 1U rackmount design. Highly efficient and reliable, the pure sine wave output of the AEP-A3000R Series offers benefits over modified or quasi-sine wave units by delivering clean output power.

The new inverters are 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 percent 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 series have 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 given as 84 to 90 percent, 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 compact, 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-in. fits easily into 1U racks.
