The Models SS and SB series are lightweight, static inverters. These models utilize the latest state of the art, solid state circuitry to invert a 28 VDC input to either a 115 VAC, 60 Hz or 230 VAC, 50 Hz sine wave output.
Design features include a crystal controlled oscillator for output frequency stability and a pulse-width-modulated square to sine wave power conversion scheme for efficient, reliable and quiet operation.
The model SS and SB Series of static inverters are designed to power laptop computers, audio/video entertainment systems, portable electronics (stereo, MP3, CD, DVD, video games, etc.), microwave ovens, coffee makers and medical equipment in airborne, marine and ground mobile applications.
