KGS公司SCA150系列逆变器

SCA150系列逆变器

DESCRIPTION

The SCA150 is a single phase, 400Hz lightweight static inverter. This model utilizes the latest state of the art, solid state circuitry to invert a 28 Vdc input to 115 Vac and 26 Vac, 400 Hz sine wave outputs.

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

The SCA150 static inverter is primarily designed to power airborne and ground instruments, compasses, gyros, radar and navigation equipment.
