Industrial open-frame AC-DC supply

The Mean Well PS-45-24 is a 45.6 W single-output unit that delivers 24 V at 1.9 A from an AC mains input. It uses an AT-type layout on a bare PCB, making it suitable for integration into custom enclosures, test rigs or OEM equipment where a compact board-level source is required.

Fits board-level builds, not ATX cases

Engineers designing embedded systems, LED drivers or industrial controllers will appreciate the fixed 24 V rail and open-frame form factor. Builders who need a standard ATX connector set, power-factor correction or a cased unit with fan cooling should look elsewhere.

Steady 45.6 W under continuous load

The supply is rated for its full 45.6 W output during sustained operation, not just peak bursts. With no power-factor correction stage, input current waveform remains non-sinusoidal, so installers should verify harmonic limits if the installation falls under applicable regulations.

Questions about this item

What AC input voltage range does the PS-45-24 accept for operation?

The PS-45-24 is an AC-DC switching power supply designed to convert mains alternating current into a regulated 24 V DC output for industrial equipment.

Can the PS-45-24 replace an older 24 V supply that delivered less than 1.9 A?

Yes, the PS-45-24 provides 24 V at up to 1.9 A, so it can power loads that previously drew less current while maintaining the same voltage.

How can I verify the PS-45-24 is delivering the correct 24 V output after wiring it?

Measure the output terminals with a multimeter set to DC volts; a reading close to 24 V confirms the unit is regulating correctly under load.
