2000W Compact Pure Sine Wave Inverter from Schaefer
Sine weave inverter.
Hopkinton, MA — Schaefer, Inc. is introducing the AEP-2000 Series of 2000W, rugged, high efficiency, pure sine wave inverters. The clean pure sine wave output of the AEP-2000 Series, with less than 3 percent total harmonic distortion, is suitable for powering sensitive loads and for improving AC equipment performance. The AEP-2000 Series is available in four standard input configurations: 24VDC, 48VDC, and also 110VDC or 220VDC which are designed and well suited for utility voltages. Outputs are available in regulated 115VAC or 230VAC (50/60Hz) versions.

All models in the AEP-2000 Series have a wide operating temperature of -20 to +50°C, comprehensive protection circuitry, and a digital display to monitor/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 up to 94 percent, depending on the model selected. EMI is minimized to Class B standards for reduced impact on other equipment.

The design is rugged and suitable for military/COTS/industrial, utility, rail/transit, satellite, computer, vehicle/mobile, marine and general backup power applications. The compact module size of 4.02 x 10.94 x 15.28-in. (102 x 278 x 388mm) provides 2000W of power, while still accommodating space-constrained installations. A simple mounting scheme and high reliability lend to the low cost of ownership.
