KFF-I-1K 3phz 400 Hz INVERTER

DESCRIPTION:

The KFF-I-1K is a lightweight and very low noise, 400Hz 3 phase static inverter, witch utilizes the latest state of the art, solid state circuitry to invert a 220V 50 HZ AC input to a 115/200 V AC, 400 Hz, 3 phase sine wave output.

Design features include a microcontroller based control board and crystal-controlled oscillator for output frequency stability and a Sin-pulsewidth-

modulated square to sine wave power conversion scheme for efficient & reliable operation.

The 3phz 400 Hz Static Inverter is primarily designed for laboratory testing airborne unit and ground instruments, compasses, gyros, radar and navigation equipment.
