Absopulse Electronics has released the CSI 280-F3 Series of compact, high-performance dc/ac sine wave inverters. The units introduce new semiconductor technology and a unique design topology that simplifies the circuitry and enables compact construction, low weight and cost, and high MTBF, the company says. The total footprint of each unit is 132 by 64 by 300 mm. CSI 280-F3 Series inverters deliver fully isolated “clean” sinusoidal output voltage of 115 VAC at 400Hz/60Hz or 230 VAC at 50Hz. They offer four standard inputs of 24, 48, 110 or 125 VDC. The input and output are filtered for low noise. The input meets EN55022 Class A conducted and radiated requirements.
