STEP-PS/ 1AC/ 5DC/2 - Power supply unit

2320513

Primary-switched STEP POWER power supply for DIN rail and direct mounting, input: 1-phase, output: 5 V DC/2 A

STEP POWER power supplies for distribution boards
The STEP POWER power supply range was developed especially for building automation. The low idling losses and high degree of efficiency ensure maximum energy efficiency. They allow flexible use and can be snapped onto the DIN rail or screwed onto an even surface.
