MURR ELEKTRONIK Switching module power supply 24V 2.5A

Murrelektronik Eco Rail Power Supply (24V DC, 2.5A)

This device is a professional Murrelektronik Eco Rail regulated switching power supply (Article Number: 85132). It is designed for efficient, space saving DIN rail mounting inside automation panels, industrial control cabinets, and power distribution systems.

The Eco Rail series focuses on providing core, heavy duty power delivery functions with high efficiency and thermal stability, ensuring a stable $24text{V DC}$ bus line for PLCs, sensors, actuators, and relays.

Key Features

Regulated DC Output Line: Outputs a highly stable, low ripple 24V DC supply current rated at 2.5A, perfectly matching standard industrial control voltage thresholds.
Adjustable Output Voltage Potentiometer: Outfitted with a front accessible trimmer potentiometer (Uout Adj. 23-28 V). This allows commissioning technicians to adjust the voltage level between $23text{V}$ and $28text{V DC}$ to compensate for inline voltage drops along long cable runs.
Universal Wide Range Input: Built to handle wide nominal input variations spanning 100V AC to 240V AC $50 / 60text{ Hz}$ standard network frequency). This allows global implementation across different regional electrical grids without requiring step down transformers.
Status Monitoring Indicator: Features an integrated green “OK” LED on the front plate to give immediate visual verification of active output regulation status during troubleshooting.
Heavy Duty Screw Terminals: Outfitted with clear pluggable or fixed screw terminal blocks at the top and bottom edges. The input and output poles are explicitly screen printed (+ + - - and L N ⏚) to minimize wiring mistakes.
