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-45-7.5-C for a 7.5V automation subsystem that needs steady DC output?

Yes, this unit provides constant voltage output at 7.5V with up to 5.4A and 40.5W available. It is suitable for automation, industrial control, or embedded loads that are specified for those limits.

Is the EPS-45-7.5-C appropriate for a 7.5V embedded computer or control board assembly?

It can be used where the embedded assembly requires a regulated 7.5V supply and draws no more than 5.4A. The listed 90-264VAC input range is also useful when the equipment may be deployed across different AC supply standards.

Can this model power a 7.5V industrial sensor hub or communications node?

Yes, if the hub or node is designed for constant 7.5V input and its total load stays within 40.5W and 5.4A. The 103.4 x 62.0 x 37.0 mm form factor may also matter when comparing enclosure space to other versions.

Would the EPS-45-7.5-C fit a compact OEM device that needs 7.5V DC from AC mains?

It is intended for OEM and embedded equipment that converts 90-264VAC input to a constant 7.5V DC output. As long as the device stays within the 5.4A and 40.5W rating, it is a valid electrical fit.

Can the EPS-45-7.5-C be used in cold or hot indoor equipment environments?

The specified operating temperature range is -30°C to +70°C, with output load derating at higher temperatures per the derating curve. No IP rating is listed, so the product information does not confirm suitability for exposed outdoor or wet locations.

What are the main 7.5V EPS alternatives to the EPS-45-7.5-C?

On this spec sheet, the other 7.5V option is the EPS-45-7.5, which shares the same 40.5W, 5.4A rating. The EPS-45-7.5-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-45-7.5.
