Bus supply unit 640 mA with auxiliary output

The Ekinex® EK-AH1-TP power supply produces and monitors the 30 Vdc voltage required to operate the KNX bus system. A coil built into the device provides decoupling between the power supply and the bus line. The output has overvoltage, overcurrent and short-circuit protection. EK-AH1-TP has an additional 30 Vdc output that can be used for auxiliary power supply to other SELV safety extra-low voltage devices. The total current made available by the two outputs (KNX bus line and auxiliary power supply) cannot exceed 640 mA. The device can support short interruptions of the line voltage.
