Why choose it

The HDN-3012 is a switching power supply built for DIN rail installation in electrical cabinets. Its wide AC input range handles unstable mains, and the adjustable output lets you compensate for voltage drop on long cable runs. Convection cooling means no fan noise or maintenance.

Ideal use cases

• Powering PLCs and industrial controllers
• Supplying sensors and transmitters in automation
• Driving small DC motors or solenoids
• Building automation and HVAC control circuits

Good to know

The unit mounts on standard TS-35/7.5 or TS-35/15 DIN rails. It includes short circuit, overload, and overvoltage protection to safeguard both the supply and connected loads.
