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-65-48-C to power a 48V PLC, relay bank, or industrial control circuit?
Yes, if the load is designed for constant-voltage 48V DC and stays within 1.36A and 65.28W. That makes it suitable for many 48V industrial control, automation, and embedded systems that need a regulated 48V supply from a 90-264VAC input.
Is the EPS-65-48-C a good fit for 48V telecom or network equipment that needs a compact internal power supply?
It can be a fit for 48V equipment that accepts a constant-voltage input and draws no more than 1.36A or 65.28W. Its 103.4 × 62.0 × 37.0 mm size and 0.3 kg weight make it suited to compact internal equipment layouts.
Can the EPS-65-48-C be used in embedded or OEM devices that need wide AC input tolerance?
Yes, it accepts 90-264VAC input and provides a constant 48V output up to 1.36A. That wide input range is useful for embedded and OEM equipment intended for varied AC mains environments.
Can I use the EPS-65-48-C for a 48V automation sensor or actuator system?
It can support 48V automation loads when the total demand does not exceed 1.36A or 65.28W. Because it is a constant-voltage model, it is best matched to equipment specified for a fixed 48V DC supply.
Is the EPS-65-48-C suitable for outdoor or harsh-temperature installations?
The operating temperature range is -30°C to +70°C (per the output load derating curve), so it is designed for a broad temperature span. No IP rating is listed in the provided specs, so outdoor suitability depends on the final enclosure rather than this power supply alone.
How does the EPS-65-48-C compare with other 48V models in the EPS series?
Within the EPS-65 series on this datasheet, the 48V options are EPS-65-48 and EPS-65-48-C, both rated 48V, 1.36A and 65.28W. EPS-65-48 is the 101.6 × 50.8 × 29.0 mm PCB version at 0.15 kg, while EPS-65-48-C is 103.4 × 62.0 × 37.0 mm at 0.3 kg; other EPS series are not covered by this sheet.

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.
