TSO’D 400 Hz LIGHTWEIGHT SINEWAVE
1 KVA STATIC INVERTER

Description:

The SC100 is a lightweight 400Hz static inverter. This model utilizes the latest state of the art, solid state circuitry to invert a 28 Vdc input to a 115 Vac, 400 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 operation.

The SC100 static inverter is primarily designed to power airborne and ground instruments, compasses, gyros, radar and navigation equipment
