Ackermann clino power supply 24V DC 20A | DIN rail, SELV

Single-phase power supply unit providing a constant DC supply for the Ackermann nurse call system according to DIN VDE 0834-1:2016-06. The compact primary-switched unit (EN 61000-3-2) is mounted on a DIN rail in the sub-distribution board; with the safety cover 89954MC it can also be wall-mounted outside the board. The output is no-load, overload and short-circuit proof and the output voltage is adjustable. A DC-OK signal (LED and relay) reports supply problems. For an uninterruptible supply, use the UPS module 89954C8.
