Test conditions and notes8
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. 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 )
- 5. Derating may be needed under low input voltage. Please check the static characteristics for more details.
- 6. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 7. EPS-25-15/24/27/36/48 without Hs1.
- 8. 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).

FAQ
Can I use the EPS-25-12 for a small 12V PLC or automation control circuit?
It can fit small 12V control loads when the total demand stays within 25.2W and 2.1A. Because it is a constant voltage 12V supply, it is better suited to equipment that expects a fixed 12V DC source rather than a variable output.
Is the EPS-25-12 suitable for powering 12V industrial sensors, relays, and panel accessories?
Yes, it can be used for groups of 12V sensors, relays, indicators, or similar panel accessories if their combined load remains under 25.2W and 2.1A. The wide 85-264VAC input also makes it practical for equipment built for different mains ranges.
Can I use this 12V power supply in an embedded system or test fixture?
It is a reasonable fit for embedded electronics or bench-style fixtures that require a constant 12V output and do not exceed 25.2W. Its 76.2 x 50.8 x 24.0 mm size also makes it easier to place in compact equipment layouts.
Is the EPS-25-12 okay for outdoor or harsh-environment use?
The published specs show an operating temperature range of -30°C to +70°C, but they do not list an IP rating. Without an IP rating in the provided specs, it should be used only where the surrounding enclosure or equipment provides the needed environmental protection.
How does the EPS-25-12 compare with the other EPS-25 models?
Within the EPS-25 group, the available models are EPS-25-3.3 at 16.5W, 3.3V, 5A; EPS-25-5 at 25W, 5V, 5A; EPS-25-7.5 at 25.5W, 7.5V, 3.4A; EPS-25-12 at 25.2W, 12V, 2.1A; EPS-25-15 at 25.5W, 15V, 1.7A; EPS-25-24 at 25.2W, 24V, 1.05A; EPS-25-27 at 25.65W, 27V, 0.95A; EPS-25-36 at 25.2W, 36V, 0.7A; and EPS-25-48 at 25.44W, 48V, 0.53A. The main difference between them is the output voltage and the corresponding maximum current.

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.
