Power Supply Units And Ups Modules

Single-phase power supply 24 V DC (20 A)

Single-phase power supply unit (20 A) for constant direct current supply to the nurse call system.

Part Number: 89954R6

Single-phase power supply unit (20 A) for constant direct current supply to the nurse call system. Compact construction using modern primary clocked circuit technology (according to EN 6100-3-2) suitable for top-hat rail mounting in sub-distribution. Using the assembly kit (safety cover) 89954 MC, wall mounting is also possible outside sub-distribution. The output of the power supply unit is idle-, overload- and short-circuit proof.
