Woehrle Einphasen-Netzgerät EPNSV1204primärgetaktet schmale Bauform

Where many power supplies settle for bulky frames and audible fans, the Woehrle EPNSV1204 takes a different route: a slim, convection-cooled chassis that slips onto a DIN rail and delivers a steady 24V DC at up to 5A. Its primary-switched design keeps efficiency above 90%, so less energy turns into heat and more goes to your load. Whether you're feeding sensors, controllers, or small actuators, this unit brings industrial dependability without the usual footprint.

Highlights

• Single-phase 100–240V AC input, 50/60 Hz, for worldwide use
• Stable 24V DC output, 5A continuous, 120W total power
• Slim, narrow form factor saves space on crowded DIN rails
• Convection cooling – no fan, no dust buildup, silent operation
• Full protection: overload, short circuit, overvoltage, overtemperature
• Low ripple & noise (<50mVpp) for sensitive electronics
• Wide operating range: -25°C to +70°C
• Screw terminals for secure, maintenance-friendly wiring

In daily use

Installation is straightforward: clip the EPNSV1204 onto a standard 35mm DIN rail, connect line, neutral, and earth to the input terminals, and wire your 24V load to the output. The screw terminals accept solid or stranded conductors and stay tight under vibration. Because the unit is convection cooled, it works well in sealed cabinets where fan-cooled supplies would recirculate hot air. The narrow profile leaves room for other modules, and the high efficiency means less heat inside the enclosure. If a fault occurs, the built-in protections shut down the output safely and recover automatically once the condition clears.
