400VA Small, Lightweight Static Inverter

TSO'd 60Hz Sine Wave Static Power Inverter
400VA - Small, Lightweight

The SS40 is a highly efficient, compact, lightweight, airborne approved static power inverter. The SS40 utilizes the latest state of the art, solid state design circuitry to invert a 28 Vdc input into 115 Vac, 60 Hz full sine wave output power.

Design features include a crystal-controlled oscillator for output frequency stability and a pulse-width-modulated (PWM) square to sine wave power conversion topology for highly regulated, efficient & reliable operation.

The SS40 static inverter is designed to power laptop computers, audio & video entertainment systems, portable electronics (stereo, MP3, CD, DVD, video games, etc.) and medical equipment in airborne, marine and ground mobile applications.
