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. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. (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. 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-15-48 for a small 48V industrial device?

Yes, if the equipment requires constant 48V and draws no more than 0.313A, this supply matches that requirement. Its output is limited to 15.02W, so it is intended for lower-power 48V electronics.

Is the EPS-15-48 suitable for compact 48V monitoring or interface equipment?

It can be suitable for compact 48V electronics that stay within 0.313A and 15.02W. The 63.5 x 45.7 x 24.0 mm footprint also helps when space is limited inside equipment or panel builds.

Will this work for a low-power 48V telecom or IT module?

It may fit a low-power 48V module if the load is within the 0.313A output current and 15.02W power rating. The wide 85-264VAC input is also useful where the AC source may vary across deployment sites.

Can I use this for a 48V embedded or automation subsystem with modest current draw?

Yes, this model is designed for constant 48V output at up to 0.313A. That makes it a better match for low-power embedded, interface, or control subsystems than for heavier 48V loads.

Is the EPS-15-48 rated for outdoor temperature swings?

The operating temperature range is -30C to +70C, with output derating at higher temperatures per the derating curve, so the electrical rating covers a broad temperature range. The provided specs do not list an IP rating, so outdoor exposure resistance is not defined here and protected installation should be assumed unless other enclosure details are available.
