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-45-24 to power a 24V PLC or industrial control circuit?
Yes, this model is a constant voltage 24V supply rated for 45.6W and 1.9A, which fits many small PLC, relay, and control-panel loads that require 24VDC. It runs from a 90-264VAC input, and the sheet also allows 127-370VDC input.
Is the EPS-45-24 suitable for 24V sensors, relays, and automation accessories in one enclosure?
It can be a fit when the connected 24V devices stay within the unit's 1.9A and 45.6W output limits. The constant voltage output is intended for 24V equipment rather than loads that require another DC voltage.
Can this power supply run a small 24V embedded or industrial PC setup?
It is appropriate for 24V embedded and industrial electronics when the total load does not exceed 45.6W or 1.9A. Buyers should match the equipment to a constant voltage 24V source and verify the power draw stays inside the published limits.
Can the EPS-45-24 be used in an indoor machine cabinet or control box?
For indoor equipment spaces, the operating temperature range of -30°C to +70°C (with output load derating per the derating curve) supports a wide range of industrial conditions. No IP rating is listed in the provided specs, so it should not be treated as a weather-exposed or washdown power supply.
How does the EPS-45-24 compare with other 24V models in the EPS series?
Among the 24V models on this spec sheet, EPS-45-24 and EPS-45-24-C share the same 45.6W, 1.9A rating. EPS-45-24 is the PCB version at 101.6 × 50.8 × 29 mm and 0.14 kg, while EPS-45-24-C is the cased version at 103.4 × 62 × 37 mm and 0.3 kg.
