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-25-7.5 for a 7.5V embedded device or OEM board?
Yes, if the product is specified for constant-voltage 7.5V DC and draws no more than 3.4A or 25.5W. It is intended for equipment that specifically calls for a 7.5V rail rather than 5V, 12V, or 24V.
Is this power supply suitable for a 7.5V instrument or controller module?
It can be suitable for 7.5V instrumentation or control electronics when the load remains within 25.5W and 3.4A. The constant-voltage output is the key fit for devices designed around a fixed 7.5V input.
Can the EPS-25-7.5 power a low-voltage automation accessory that requires 7.5V DC?
Yes, for automation accessories or specialty modules that are rated for 7.5V DC and stay at or below 3.4A. Because this is a constant-voltage model, it should be matched only to loads that specify a 7.5V input.
Does the EPS-25-7.5 work in cold or warm indoor equipment environments?
The stated operating range is -30°C to +70°C, which supports a wide span of indoor equipment conditions. No IP rating appears in the provided specs, so those specs do not confirm suitability for exposed outdoor or wet environments.
What should I compare when choosing between the EPS-25-7.5 and other EPS-25 models?
The EPS-25 series spans 3.3V 5A at 16.5W, 5V 5A at 25W, 7.5V 3.4A at 25.5W, 12V 2.1A at 25.2W, 15V 1.7A at 25.5W, 24V 1.05A at 25.2W, 27V 0.95A at 25.65W, 36V 0.7A at 25.2W, and 48V 0.53A at 25.44W. The selection point is the exact voltage and corresponding current available from each version, not a change in overall form factor.

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.
