Application

Network power supplies feed the industrial electronics found in electronic cabinets, for example solenoid valves, lights, sensors, relays, controls, etc.

Function and design

The devices are supplied via a alternating voltage (115 V AC or 230 V AC). The output operates with either a regulated or unregulated direct voltage.

The module is protected by fuses from excessive loads and short circuits. When necessary, the negative potential can be jumpered to other devices through the output.

A properly functioning module is indicated via a LED (green) at the output.
