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. "All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness." 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 EPS-45S-24 for a 24V industrial sensor controller or automation module?
Yes, this model provides constant voltage output at 24V with up to 1.9A and 45.6W available. It is appropriate for industrial sensing, automation, or embedded equipment designed for 24V DC within those limits.
Is the EPS-45S-24 suitable for 24V embedded systems in compact OEM equipment?
It can be a fit for compact OEM equipment that needs a regulated 24V source and draws no more than 1.9A. The 76.2 x 50.8 x 24.0 mm size is useful where board space and enclosure depth are limited.
Would this 24V power supply work for industrial communications or control electronics?
Yes, if the electronics are designed for constant 24V input and stay within the 45.6W and 1.9A rating. The 80-264VAC input range also helps when the equipment is intended for multiple AC input standards.
Can the EPS-45S-24 be used in monitoring or data-acquisition equipment that runs on 24V?
It is suitable for monitoring, data-acquisition, or automation assemblies that require regulated 24V DC. The supported output is up to 1.9A, with total output power rated at 45.6W.
Is the EPS-45S-24 okay for outdoor cabinets or exposed locations?
No IP rating is listed, so the available product data does not establish outdoor or exposed-environment suitability. The operating temperature range is -30°C to +70°C, but that temperature rating does not replace an IP enclosure rating.
How does the EPS-45S-24 compare with other 24V models in the EPS lineup?
The EPS-45S spec sheet lists one 24V model, the EPS-45S-24 at 45.6W and 1.9A. The other versions are EPS-45S-3.3 at 26.4W, 3.3V, 8A; EPS-45S-5 at 40W, 5V, 8A; EPS-45S-7.5 at 40.5W, 7.5V, 5.4A; EPS-45S-12 at 45.6W, 12V, 3.8A; EPS-45S-15 at 45W, 15V, 3A; and EPS-45S-48 at 45.1W, 48V, 0.94A. The EPS-45S-24 shares the series' highest rated power of 45.6W with the EPS-45S-12.

Replacement PS
Model: EPS-15-15 ×1, EPS-15-5 ×1, EPS-15-7.5 ×1Quantity: 1Power Supplies were used to replace the one that was removed on a Phillips PM6680 counter, a +5V, +15V and -7V. They seem to work well so far. I have to put in a boost converter on the +15V for space and not use the +15V EPS.
