150 W AC-DC power supply for 12 V equipment

This unit converts AC mains to a regulated 12 V DC output at 12.5 A for 150 W total power. It suits industrial devices, LED strips, CCTV systems and similar 12 V loads. The wide input range accepts 85 V to 265 V AC so it works on global mains voltages. Buyers needing higher current or different output voltages should choose another model.

Metal case with built-in protections

The aluminium enclosure provides shielding and helps dissipate heat without a fan. Screw terminals on the output side allow secure wiring for permanent installations. Over-voltage, over-current and short-circuit protection are integrated to guard connected equipment. The supply is rated for indoor use only between 0 °C and 40 °C ambient.

Check your load and mains wiring first

Verify that your equipment draws no more than 12.5 A at 12 V before ordering. Confirm the local mains voltage falls within the 85 V to 265 V AC range. Ensure you have an appropriate earthed AC cable and that the installation location stays within the stated temperature and humidity limits. No AC lead is included in the package.
