Industrial open-frame power supply

The Mean Well PS-45-12 is an AT-type AC-DC unit delivering 12 V at 3.7 A for a total of 44.4 W. It targets engineers and technicians who need a compact, single-output board supply for embedded systems, test rigs or industrial equipment.

Installation notes

The open-frame PCB design means the supply mounts directly inside a chassis without an external enclosure. Clearance for airflow and proper insulation of mains terminals are the installer's responsibility; no fan or mounting hardware is included in the package.

Sustained-load behaviour

Rated for continuous operation at 44.4 W, the unit maintains its 12 V output without the derating that short-burst ratings can hide. It lacks active power-factor correction, so input current waveform and harmonic limits should be checked against site standards before long-term deployment.

أسئلة حول هذا المنتج

How can I verify the PS-45-12 is delivering 12 V at 3.7 A after installation?

Measure the output terminals with a multimeter under load; a reading near 12 V while drawing up to 3.7 A confirms the 44.4 W unit is operating correctly.

What ships with the PS-45-12 and what must I source separately?

The package includes one PS-45-12 unit and a free gift; input cables, output connectors and any mounting hardware are not included and must be purchased separately.

Which PS-45-12 variant should I select for a 12 V 44.4 W requirement?

The PS-45-12 is a single 12 V 3.7 A 44.4 W model; choose this version when your design calls for exactly 12 V at up to 3.7 A.
