The KGS Electronics SPC-6-750A is a solid-state frequency changer that converts single-phase 50/60 Hz input power to 400 Hz output power, delivering stable precision frequency conversion for avionics and marine equipment. This FAA-certified unit accepts 115 VAC ±15 VAC input and produces dual output rails: 115 VAC at 750 VA and 26 VAC at 500 VA, both as clean sine waves. Built-in protection includes input overvoltage shutdown above 135 VAC, 15 AMP circuit breaker overcurrent protection, and internal safeguards against overload, voltage transients, and short circuits.
