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-45-15 for a 15V industrial control or instrumentation circuit?

Yes, if the equipment is designed for constant-voltage 15V DC and its total draw stays within 3A and 45W. That makes it suitable for many low-power control, measurement, and instrumentation loads that require a fixed 15V rail.

Is the EPS-45-15 a fit for embedded test equipment or a 15V electronics bench assembly?

It can be, when the load requires 15V DC and does not exceed 45W. The 3A rated output current must cover the total draw of the assembly.

Can this model power 15V analog modules or signal-conditioning electronics?

Yes, if the total 15V load remains at or below 3A and 45W. The main match is a constant-voltage 15V requirement rather than a current-regulated output.

Would the EPS-45-15 work for IT or communications equipment that uses a 15V rail?

It can work for IT or communications hardware when the device is specified for 15V DC and stays within 45W. Its 90-264VAC input also supports use across a broad AC input range.

Is the EPS-45-15 suitable for indoor equipment in cold or warm operating conditions?

The stated operating range is -30°C to +70°C, with output load derating at higher temperatures per the derating curve. No IP rating is listed in the provided specs, so those specs do not confirm exposed outdoor or wet-area suitability.

How does the EPS-45-15 compare with other 15V EPS models?

Among the 15V models on this spec sheet, EPS-45-15 and EPS-45-15-C share the same 45W, 3A rating. EPS-45-15 is the PCB version at 101.6 × 50.8 × 29 mm and 0.14 kg, while EPS-45-15-C is the cased version at 103.4 × 62 × 37 mm and 0.3 kg.

  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.
