Test conditions and notes8
- 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. 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. Derating may be needed under low input voltage. Please check the static characteristics for more details.
- 6. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 7. EPS-35-24/27/36/48 without Hs1.
- 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-35-48 for a 48V control or industrial electronics load?
Yes, if the load requires 48V constant voltage and draws up to 0.75A, because this supply is rated for 36W at 48V. It fits lower-power industrial, embedded, and automation electronics that need a regulated 48V DC source from 85-264VAC input.
Is the EPS-35-48 suitable for compact internal 48V equipment designs?
It is appropriate for internal equipment that needs a compact 48V AC-DC supply with modest current demand. The 76.2 × 50.8 × 24.0 mm size and 0.085 kg weight support use in space-limited control housings or embedded assemblies.
Can this power supply run a 48V panel subsystem or communications device?
It can support 48V devices as long as the total load stays within 0.75A and 36W. That makes it suited to lower-power 48V electronics rather than applications that require more than 0.75A.
Can the EPS-35-48 be used outdoors or in washdown areas?
Its operating temperature is specified from -30°C to +70°C, but no IP rating is listed in the product data provided here. That supports temperature-based selection, but it does not establish protection against water or dust exposure.

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.
