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-45-7.5 for a 7.5V industrial controller or HMI that needs a regulated DC supply?
Yes, this model is a constant voltage power supply with a 7.5V output rated for up to 5.4A and 40.5W. That makes it suitable for 7.5V industrial control, automation, or embedded equipment that must stay within those electrical limits.
Is the EPS-45-7.5 a good fit for embedded electronics or test fixtures that run on 7.5V?
It can be a fit for embedded assemblies, bench fixtures, or control boards that require a constant 7.5V source and draw no more than 5.4A. Its compact 101.6 x 50.8 x 29.0 mm size also helps where internal space is limited.
Can this 7.5V power supply be used in low-voltage automation equipment inside a machine cabinet?
Yes, if the automation load is designed for 7.5V constant voltage and stays within the 40.5W and 5.4A rating. The wide 90-264VAC input also supports use in equipment built for varied AC input conditions.
Would the EPS-45-7.5 work for a 7.5V embedded device that stays powered continuously?
It is intended for regulated 7.5V DC output up to 5.4A, which suits continuously powered embedded or industrial electronics operating within that load range. The average load should stay at or below the 40.5W rated power.
Is the EPS-45-7.5 suitable for outdoor or washdown environments?
No IP rating is listed for this model, so the product information does not establish protection for outdoor or washdown exposure. The operating temperature range is -30°C to +70°C with output load derating per the derating curve, but environmental sealing is not specified.
How does the EPS-45-7.5 compare with other 7.5V models in the EPS series?
Among the 7.5V models on this spec sheet, EPS-45-7.5 and EPS-45-7.5-C share the same 40.5W, 5.4A rating. EPS-45-7.5 is the PCB version at 101.6 × 50.8 × 29 mm and 0.14 kg, while EPS-45-7.5-C is the cased version at 103.4 × 62 × 37 mm and 0.3 kg.

Replacement PS
Model: EPS-15-15 ×1, EPS-15-5 ×1, EPS-15-7.5 ×1Quantity: 1Power 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.
