NTZ-24.3 Power Supply

The NTZ-24 Power Supply delivers filtered DC voltage to supply indicator lights, control relays, and other low-voltage devices with current consumptions lower than 1 Ampere. CBy connecting an external 24V power supply to the connected consumers, the supply of this consumers will be done via external power, if operating voltage failure occurs. Fault messages via relay output. Note: When replacing the NTZ-24.3 with its successor unit, the NTZ-24.4, be sure to replace the associated plug-in connector as well!
