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-35-24/27/36/48 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-35-12 for a 12V PLC accessory or industrial control device?
Yes, if the equipment is designed for constant-voltage 12V DC and its total draw stays within 3A and 36W. That makes it suitable for many low-power PLC accessories, relays, interface modules, and control electronics.
Is the EPS-35-12 a fit for a 12V HMI, display, or embedded panel computer?
It can be, when the device requires 12V DC and does not exceed 36W. The 3A rated output current sets the limit for the panel or display load.
Can this 12V model power sensors, fans, and small automation loads in one enclosure?
Yes, if the combined 12V load remains at or below 3A and 36W. For grouped low-power panel devices, the important check is the total demand on the 12V rail rather than each load individually.
Is the EPS-35-12 suitable for indoor equipment exposed to temperature swings?
The published operating range is -30°C to +70°C, which supports a wide range of equipment-enclosure temperatures. No IP rating is listed in the provided specs, so the data does not show exposed outdoor or washdown suitability by itself.

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.
