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-90-12ST for a 12V automation system with multiple control loads?

It can suit 12V automation assemblies when the total constant-voltage load stays within 80.4W and 6.7A. That makes it relevant for grouped 12V control electronics rather than low-power single-load applications.

Is the MPM-90-12ST a fit for 12V embedded computing or industrial electronics?

Yes, if the equipment needs 12V constant voltage and does not exceed 6.7A output current. The screw terminal style and 109.0 × 52.0 × 33.5 mm size make it more suitable where wired screw terminal connections are preferred over PCB mounting.

Can this model power 12V medical electronics?

This version is medical safety approved, so it is aligned with medical-oriented equipment categories better than a standard commercial-only supply. The electrical match still has to be correct: 12V output, 80.4W rated power, and 6.7A rated current.

Would the MPM-90-12ST work for 12V monitoring, control, or test equipment?

It can be used where the equipment expects a constant-voltage 12V supply and the load stays within 80.4W. The 80-264VAC input range also supports use across a broad AC input range without changing the output rating.

Can the MPM-90-12ST be used outdoors?

The listed operating temperature range is -30°C to +80°C, but no IP rating is provided in the published specs. Without an IP rating on the product page, outdoor dust or water exposure is not defined by this listing.

What is the difference between the MPM-90-12ST and the other 90-series options?

The 90-series options are MPM-90-12 and MPM-90-12ST at 80.4W, 12V, 6.7A; MPM-90-15 and MPM-90-15ST at 85.05W, 15V, 5.67A; MPM-90-24 and MPM-90-24ST at 90W, 24V, 3.75A; and MPM-90-48 and MPM-90-48ST at 90.2W, 48V, 1.88A. The ST MPM-90-12ST uses a 109.0 × 52.0 × 33.5 mm body, while the non-ST MPM-90-12 is smaller at 87.0 × 52.0 × 29.5 mm.
