SC50 Static Inverters 400Hz 500 VA
(KGS products can only be shipped to U.S. address only.)
(DAI Part# SC50)
The SC50 is a lightweight, static inverter that 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 and reliable operation.
The SC50 is primarily designed to power airborne and ground instruments, compasses, gyros, radars and navigation equipment.
