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-65-36 for 36V industrial control or automation equipment?

Yes, if the load is designed for constant 36V input and stays within 1.81A and 65.16W. That makes it appropriate for 36V automation devices, control assemblies, and OEM electronics that require a fixed-voltage DC supply.

Is the EPS-65-36 suitable for 36V embedded systems or industrial electronics?

It is suitable for embedded or industrial equipment that expects a regulated 36V output and draws no more than 1.81A. The constant-voltage design is intended for devices specified for a fixed 36V supply rather than a constant-current source.

Can this model power 36V sensors, controllers, or test equipment in an OEM enclosure?

Yes, provided the total demand is within 65.16W and 1.81A at 36V. Its compact 101.6 × 50.8 × 29.0 mm size can also help in space-constrained enclosed equipment.

Is the EPS-65-36 meant for indoor or outdoor environments?

The operating temperature range is -30°C to +70°C (per the output load derating curve), so it can handle a wide temperature span in protected equipment. Since no IP rating is listed in the provided specs, it is better treated as an indoor or enclosure-mounted power supply rather than an exposed outdoor unit.

How does the EPS-65-36 compare with other 36V models in the EPS series?

Within the EPS-65 series on this datasheet, the 36V options are EPS-65-36 and EPS-65-36-C, both rated 36V, 1.81A and 65.16W. EPS-65-36 is the 101.6 × 50.8 × 29.0 mm PCB version at 0.15 kg, while EPS-65-36-C is 103.4 × 62.0 × 37.0 mm at 0.3 kg; other EPS series are not covered by this sheet.

  1. Replacement PS

    By Gary Z.|2026-07-09✓ Verified Buyer
    Model: EPS-15-15 ×1, EPS-15-5 ×1, EPS-15-7.5 ×1Quantity: 1

    Power 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.
