Test conditions and notes8
  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. 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 )
  5. 5. Derating may be needed under low input voltage. Please check the static characteristics for more details.
  6. 6. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  7. 7. EPS-25-15/24/27/36/48 without Hs1.
  8. 8. 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-25-48 for a 48V industrial controller or network appliance?

Yes, if the equipment is designed for constant-voltage 48V DC and draws no more than 0.53A or 25.44W. It is better suited to low-power 48V electronics than to higher-current 48V loads.

Is this a good fit for a 48V embedded communication or monitoring device?

It can be a fit when the device expects a regulated 48V input and its total load stays within 0.53A. For embedded communication, monitoring, or control hardware, the deciding factor is matching the 48V constant-voltage requirement and the 25.44W ceiling.

Can the EPS-25-48 power a small 48V automation subsystem?

Yes, for small 48V automation electronics that stay within 25.44W and 0.53A. It is intended for constant-voltage loads, so it should be matched to electronics and modules specified for 48V DC operation.

Can this 48V unit be used in low-temperature or high-temperature equipment enclosures?

The specified operating range is -30°C to +70°C, which covers a wide span for enclosed equipment. No IP rating is listed in the provided specs, so those specs do not establish exposed outdoor or wet-location suitability on their own.

What are the main differences between the EPS-25-48 and other EPS-25 versions?

The EPS-25 family includes 3.3V 5A at 16.5W, 5V 5A at 25W, 7.5V 3.4A at 25.5W, 12V 2.1A at 25.2W, 15V 1.7A at 25.5W, 24V 1.05A at 25.2W, 27V 0.95A at 25.65W, 36V 0.7A at 25.2W, and 48V 0.53A at 25.44W. This model is the 48V option in that group, with the lowest output current among the EPS-25 variants listed.
