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-90-24ST for a 24V industrial control or automation system?

This model is a constant voltage 24V supply rated for 90W and 3.75A, so it fits 24V equipment that stays within those limits. That makes it suitable for many industrial control, automation, and embedded systems designed for a 24V DC bus. Buyers should match the load to the 24V output and keep total draw at or below 3.75A.

Is the MPM-90-24ST a fit for embedded or compact medical equipment that needs low leakage current?

The unit is described as medical safety approved and has extremely low leakage current, which is relevant for medical and embedded equipment requirements. Its compact 109.0 x 52.0 x 33.5 mm size also helps where internal space is limited. It is still a 24V constant voltage supply with a 90W, 3.75A output, so the end equipment must be designed for that input.

Can this 24V power supply run a higher-load 24V HMI, panel PC, or control accessory?

It is intended for 24V DC loads up to 90W total, with up to 3.75A available output current. A 99W peak is allowed for up to 10 seconds, as long as the average output stays within the rated power. It should only be used where the equipment requires a regulated 24V constant voltage input.

Is the MPM-90-24ST suitable for outdoor or harsh-temperature locations?

The published operating temperature range is -30C to +80C, so the product is specified for a wide temperature span. However, no IP rating is listed in the provided specs, so the product data does not confirm outdoor, washdown, or weather-exposed use. The environmental information here supports temperature review, but not ingress protection claims.

How does the MPM-90-24ST compare with other 24V models in the MPM series?

This datasheet covers the MPM-90 series, where the 24V models are the MPM-90-24 and the MPM-90-24ST, both rated 90W and 3.75A. The MPM-90-24 is the PCB mounting style at 87.0 x 52.0 x 29.5 mm, while the MPM-90-24ST is the screw terminal style at 109.0 x 52.0 x 33.5 mm. Other MPM wattages are not covered by this sheet.
