Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltage. Please check the static characteristics for more details.
  5. 5. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  6. 6. 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 )
  7. 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).

FAQ

Can I use the EPS-65-12 for a 12V automation controller or PLC accessory load?

Yes, if the equipment requires constant 12V DC and the total demand stays within 5.42A and 65.04W. That makes it suitable for many 12V automation controllers, PLC accessory loads, and related industrial electronics.

Is the EPS-65-12 a good fit for 12V HMI, display, or operator interface systems?

It can be a good fit when the HMI or display system runs on 12V constant voltage and remains under 65.04W. Short peaks up to 72W for 10 seconds are allowed, provided the average power stays within the rating.

Would this 12V supply work for industrial monitoring, alarm, or communication hardware?

Yes, for 12V DC hardware that needs a regulated constant voltage source and draws no more than 5.42A. That aligns with many monitoring, alarm, and communication assemblies used inside industrial control equipment.

Can the EPS-65-12 power multiple low-voltage 12V devices inside one enclosure?

It can support multiple 12V devices as long as the combined load stays within 65.04W and 5.42A. The 101.6 x 50.8 x 29.0 mm form factor is also suited to internal use inside an enclosure.

Is the EPS-65-12 suitable for outdoor or exposed industrial locations?

No IP rating is provided in the listed specs, so this unit is better considered for protected indoor enclosures rather than exposed outdoor mounting. Its operating temperature range is -30°C to +70°C (per the output load derating curve), but environmental suitability should still be judged with the lack of a stated IP rating.

How does the EPS-65-12 compare with the other EPS-65 and EPS-65S models?

The EPS-65 group includes EPS-65-3.3 at 36.3W, 3.3V, 11A; EPS-65-5 at 55W, 5V, 11A; EPS-65-7.5 at 60W, 7.5V, 8A; EPS-65-12 at 65.04W, 12V, 5.42A; EPS-65-15 at 65.1W, 15V, 4.34A; EPS-65-24 at 65.04W, 24V, 2.71A; EPS-65-36 at 65.16W, 36V, 1.81A; and EPS-65-48 at 65.28W, 48V, 1.36A. EPS-65S models are not covered by this datasheet, so check their own sheet for ratings.
