Test conditions and notes7

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. Derating may be needed under low input voltage. Please check the static characteristics for more details.
5. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
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. 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-45-5-C for a 5V industrial controller or processing board?

Yes, if the controller requires 5V constant voltage and draws no more than 8A. With 40W available output, it suits higher-current 5V electronics used in industrial control and embedded processing systems.

Is the EPS-45-5-C a fit for 5V automation electronics with several low-voltage loads?

It can be, provided the combined load remains within 40W and 8A at 5V. That makes it useful for grouped 5V logic, sensor, and interface electronics in automation assemblies.

Would this power supply work for 5V lab, QA, or production test fixtures?

Yes, for fixtures that need a stable 5V constant-voltage rail with relatively high current available. The 90-264VAC input also helps when the same equipment may be used in different mains regions.

Can the EPS-45-5-C support a 5V communications or display subsystem?

Yes, if the subsystem is designed for 5V DC and stays within the 8A output ceiling. Its 103.4 × 62.0 × 37.0 mm housing gives the same electrical rating as the EPS-45-5 in a larger package.

Is the EPS-45-5-C suitable for outdoor cabinets or damp locations?

The specs define operation from -30°C to +70°C, with output load derating per the derating curve, but no IP rating is listed. That means the temperature range is specified, while protection against water or dust ingress is not stated in the product data.

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.
