SC100 Static Inverter / 1000 VA / 28 VDC to 115 VAC / 400 Hz

The SC100 is a lightweight, 400 Hz static inverter that uses state-of-the-art, solid state circuitry to invert a 28 VDC input to a 115 VAC, 400 Hz sine wave output. The SC100 unit is primary designed to power airborne and ground instruments, compasses, gyros, radar, and navigation equipment.

Features

• Crystal controlled oscillator design provides output frequency stability
• Pulse width modulated square wave to sine wave power conversion scheme offers efficient, reliable, and quiet operation
• Certified to FAA TSO-C73 airborne standards
