Power Supply (DIN rail) mean well HDR-150-12 12V 150W 11.3A

Mean Well HDR-150-12 is a DIN-rail mounted switching power supply that provides a regulated 12V DC output at up to 11.3A (150W). Built for industrial and control panel installations, this compact unit supports continuous operation with stable voltage regulation and protections typical of switched-mode supplies. Its form factor is optimized for DIN-rail mounting to save panel space while delivering sufficient current for a range of automation and control devices.

Advantages

The HDR-150-12 offers a compact DIN-rail design that simplifies integration into control cabinets and distribution racks. It provides a stable 12V output suitable for sensitive electronics and supports a rated 150W power delivery with built-in protections against overload, short circuit and overvoltage, ensuring reliable operation in demanding environments. The switching topology improves efficiency and reduces heat generation compared with linear alternatives, while standardized mounting makes service and replacement straightforward.

Suitable for

• Industrial control panels and PLC power supply
• Relay coils, sensors and automation modules
• LED strips and control lighting requiring 12V DC
• Embedded controllers, communication modules and low-voltage peripherals

Key specifications

• Output voltage: 12 V DC
• Maximum output power: 150 W
• Maximum output current: 11.3 A
• Mounting: DIN-rail (TS35) compatible
• Topology: switching power supply with regulated output
• Intended use: continuous operation in control cabinets and industrial environments

How to use

Mount the unit on a standard TS35 DIN-rail inside a suitably ventilated control cabinet. Connect the AC input according to local electrical codes and ensure correct grounding. Wire the 12V DC output to the load using appropriately rated conductors and observe polarity. Verify the total connected load does not exceed the rated 150W and allow clearance for airflow around the unit. During commissioning, monitor output voltage under load to confirm regulation and check protective functions by simulating overcurrent conditions if required for validation.

Usage recommendations

Install the power supply in a dry, dust-minimized environment with adequate clearance for heat dissipation. Use fuses or circuit breakers on the input and consider adding output protection for critical loads. Avoid exceeding the maximum rated current to prevent thermal stress; if multiple devices are powered, calculate cumulative current draw including inrush currents. Regularly inspect terminal connections and ventilation paths as part of preventive maintenance.
