Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Touch current was measured from primary input to DC output.
7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
8. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

Can I use the MPM-45-24ST for a 24V PLC or automation control panel?

Yes, this model is a constant voltage 24V supply rated for 45.1W and 1.88A. That makes it a fit for 24V industrial control loads, PLC-related circuits, or panel devices that stay within 1.88A total demand.

Is the MPM-45-24ST suitable for 24V embedded or industrial electronics?

It can be used where the electronics require a regulated 24V DC output and the total load does not exceed 45.1W or 1.88A. Its compact screw-terminal format at 109.0 x 52.0 x 33.5 mm also makes it easier to place in space-constrained equipment.

Can this 24V power supply be used in medical-related equipment power sections?

The unit is described as medical safety approved, so it may be considered for equipment power sections that need a 24V constant voltage source. The electrical limit is still 45.1W at 1.88A, so the connected 24V load must remain within that output range.

Is the MPM-45-24ST appropriate for harsh temperature environments?

The specified operating temperature range is -30°C to +80°C, which is broad for industrial environments. However, no IP rating is listed in the provided specs, so those specs do not establish dust or water protection for outdoor or washdown exposure.

How does the MPM-45-24ST compare with other MPM 45-series outputs?

Within the MPM 45-series, the sibling outputs are 12V at 45W and 3.75A, 15V at 45W and 3A, 24V at 45.1W and 1.88A, 48V at 45.1W and 0.94A, and 5V at 40W and 8A. ST versions also exist for 12V, 15V, 48V, and 5V, while this unit is the ST version of the 24V 45.1W model.
