The Schneider Electric MTN6513-1203 is a SpaceLogic KNX power supply rated at 320 mA for small to medium KNX lines. Finished in white (RAL 9003), it delivers regulated 30 V DC on a choked bus output and provides a 30 V DC auxiliary output for local peripherals.

Two units can be connected in parallel for up to 640 mA on one line. Front LEDs indicate RUN, overload, and bus voltage; a floating signaling contact supports remote monitoring. For bus-only 320 mA without aux output, compare MTN684032; for 640 mA see MTN6513-1202 or MTN684064.
