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-45-48-C for a 48V PLC accessory or industrial interface module?
Yes, if the module needs 48V constant voltage and draws no more than 1A. With 48W available output, it fits smaller 48V industrial interface and control accessories that stay inside that power budget.
Is this power supply appropriate for a 48V communications or control panel subsystem?
It can be, provided the subsystem is rated for 48V DC and remains within the 48W, 1A output limit. The wide 90-264VAC input is also useful for panels deployed in regions with different AC mains standards.
Would the EPS-45-48-C work for 48V embedded hardware evaluation or burn-in rigs?
Yes, for evaluation rigs or test assemblies that need 48V constant voltage up to 1A. This makes it suitable for low-power embedded and electronics test applications built around a 48V DC rail.
Can this be used for a small 48V automation or telemetry load?
Yes, if the load requires 48V DC and does not exceed 48W. Its 103.4 × 62.0 × 37.0 mm dimensions give more room than the smaller EPS-45-48 version while keeping the same 48V, 1A output rating.
Is the EPS-45-48-C rated for outdoor or exposed-environment service?
The product specs list an operating temperature range of -30°C to +70°C, with output load derating per the derating curve, but they do not list an IP rating. That means the temperature range is defined, but the published data does not support direct exposure to rain, dust ingress, or washdown conditions.

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.
