SEA150
TSO'D 3ø 400 Hz STATIC INVERTER
1.5 KVA Lightweight
DESCRIPTION:
The SEA150 is a lightweight, 400Hz 3 phase static inverter. This model utilizes the latest state of the art, solid state circuitry to invert a 28 Vdc input to a 115/200 Vac, 400 Hz, 3 phase 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 SEA150 static inverter is primarily designed to power airborne and ground instruments, compasses, gyros, radar and navigation equipment.
