Schneider Electric’s Square D 9070-K500D1 is a 500 VA, single-phase industrial control transformer that provides 120 V control power from higher-voltage mains. It uses dual primary windings for input options of 240 VAC or 480 VAC and includes a 120 VAC secondary to feed control circuits such as relays, contactors, and timers in industrial panels. Part of the 9070 family, this transformer is designed for typical control-power applications in equipment and automation installations where a reliable 120 V control source is required.
