DIN rail switching power supply No name HDN-3012 12V 24W 2A

DIN rail switching power supply No name HDN-3012 12V 24W 2A is a compact, DIN-rail mountable switching supply that provides a regulated 12 V DC output with a maximum current of 2 A and maximum output power of 24 W. It is designed to deliver low-voltage power in industrial cabinets and control panels where space is limited. The unit features a metal enclosure sized for standard DIN-rail installation and includes the basic protection functions commonly found in switching power supplies to support reliable operation of connected low-power devices.

Advantages

The supply provides a stable regulated 12 V output with up to 2 A current in a compact form factor suitable for DIN-rail mounting. Its switching topology offers higher efficiency and reduced heat generation compared with linear supplies of similar capacity. The enclosed design and standard DIN-rail compatibility simplify integration into electrical cabinets and automation panels. Protection features typical for switching supplies help reduce risk to connected equipment during overload or short-circuit conditions.

Suitable for

• Powering control panels and PLC modules that require 12 V DC
• Supplying security and alarm systems with low current needs
• Providing power to sensors, relays, and low-power actuators
• Use in industrial automation cabinets and electrical enclosures

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 2 A
• Maximum output power: 24 W
• Mounting: standard DIN-rail compatible enclosure
• Topology: switching (SMPS) for improved efficiency

How to use

Install the power supply on a standard DIN rail inside the control cabinet or enclosure, ensuring adequate ventilation and clearance from heat sources. Connect the AC input to the appropriate mains supply according to local electrical codes and the unit's input rating. Connect the 12 V DC output to the load, observing correct polarity and within the 2 A current limit. Verify connections before powering the unit and monitor initial operation to ensure the load does not exceed the rated capacity.

Usage recommendations

For reliable long-term operation, keep the supply within its specified ambient temperature range and avoid locating it near strong heat sources. Ensure the total connected load remains below the rated 2 A and provide proper fusing or circuit protection on the input and output circuits where required by local regulations. Periodically inspect terminals for secure connections and replace the unit if any signs of overheating or abnormal behavior appear.
