The KGS Electronics SPC-6-750 is a solid-state frequency changer that converts standard AC input power into a stable 400 Hz sine wave output. Single-phase design with dual output voltage capability (115 VAC and 26 VAC) delivers up to 750 VA total power, making it ideal for avionic test benches, radar systems, compass calibration, and flight simulator power supplies. Built-in protection includes input overvoltage shutdown (>135 VAC), 15 A circuit breaker, output frequency monitoring, and audible overload warning.
