Industrial 150W Switching Supply

The Analog Technologies ALRS12V12R5AT is a 150W enclosed switching power supply that converts 90–264VAC input to a regulated 12VDC output at 12.5A. It is built for industrial equipment, 3D printers, LED lighting systems and similar loads that require a stable 12V rail in a compact metal chassis. The unit measures 1.65 inches (42mm) in height and includes a built-in long-life fan for active cooling. It is rated for continuous operation between 10°C and 60°C.

Verify Voltage and Current Before Installing

Confirm that your equipment requires exactly 12VDC and does not exceed the 12.5A (150W) continuous output rating. The supply accepts a wide 90–264VAC range, so it works on both 110V and 220V mains without manual switching, but the load must stay within the stated current limit. Ensure the enclosure has adequate airflow for the internal fan and that the mounting orientation allows the vented surfaces to dissipate heat. The all-metal case provides EMI shielding, so plan grounding accordingly.

Replaces Larger Linear or Lower-Efficiency Units

This supply replaces bulkier linear power supplies or older switching units that run hotter and occupy more panel space. The >85% efficiency and 5G anti-vibration rating make the jump worthwhile when equipment must run continuously in harsh environments or when cabinet depth is limited to the 42mm profile. The 300VAC surge withstand for 5 seconds adds a margin of safety for unstable mains that lesser supplies lack. If your application needs a different output voltage or more than 150W, this model will not fit.

Questions about this item

Does the ALRS12V12R5AT ship with the AC power cord and mounting hardware, or must those be purchased separately?

The unit is an enclosed metal power supply with a built-in fan and screw terminals for input and output; an IEC mains lead and mounting screws are not included.

Should I choose the 12 V 12.5 A model or a different voltage version for my 150 W 3D printer?

The ALRS12V12R5AT delivers exactly 12 V at up to 12.5 A for 150 W; select this model when your load requires 12 VDC.

What does the 150 W rating mean when the supply is running inside a hot printer enclosure at 50 °C?

It is rated for continuous 150 W output from 10 °C to 60 °C with efficiency above 83 %, so full power is available at 50 °C.
