C (this model)
Enclosed type
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-45-24-C for a 24V access control or security power application indoors?

It can fit indoor 24V control equipment that needs a constant voltage output and stays within 45.6W and 1.9A. The wide 90-264VAC input range also suits sites where the AC source may vary within that published range.

Is the EPS-45-24-C a good choice for 24V industrial indicators, relays, or panel devices?

Yes, for 24V panel devices and automation accessories, this unit provides a constant voltage 24V output with up to 1.9A available. The total connected load should remain at or below 45.6W.

Can this model power a compact 24V HMI or controller assembly?

It is intended for 24VDC equipment and can support compact controller or HMI assemblies when the combined demand does not exceed 1.9A and 45.6W. As with any constant voltage supply, the connected equipment should be specified for 24V operation.

Is the EPS-45-24-C suitable for outdoor or harsh exposed environments?

The operating temperature range is -30°C to +70°C, with output load derating per the derating curve, which supports broad temperature conditions inside equipment. However, no IP rating is provided in the specs, so it should not be assumed suitable for exposed outdoor, wet, or dust-heavy locations without additional protection.

What are the main 24V alternatives around the EPS-45-24-C in the same series?

On this spec sheet, the other 24V option is the EPS-45-24, which shares the same 45.6W, 24V, 1.9A rating. The EPS-45-24-C is the cased version at 103.4 × 62 × 37 mm and 0.3 kg, versus 101.6 × 50.8 × 29 mm and 0.14 kg for the PCB-type EPS-45-24.

  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.
