Pure Sine Wave Inverters
Schaefer, Inc. introduced its AEP-A2000R series of pure sine wave inverter products with 2 KVA packaged in a 1U rackmount design. The series provides clean output power for powering sensitive loads and for improving AC equipment performance. The series is available in three standard input configurations of 12V DC, 24V DC and 48V DC. Outputs are available in 115V AC or 230V AC (50 Hz/60 Hz) versions, which are regulated to ±3 percent or better. A built-in 4 ms to 6 ms automatic bypass switch allows for redundant operation from utility power if the DC supply drops out. Efficiency is 86 percent to 92 percent, depending upon the model selected.
