Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. 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).
7. 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

Can I use the EPS-65S-15 for 15V industrial control electronics?

It is intended for constant-voltage 15VDC loads and can supply up to 65.1W or 4.34A. That makes it relevant for industrial or automation devices designed specifically for a 15V rail. Confirm the equipment requires 15V rather than 12V or 24V.

Is the EPS-65S-15 a good fit for embedded systems that run on a 15V DC bus?

This power supply can fit embedded or test equipment built around a 15V constant-voltage input, provided the load stays within 4.34A. Its compact 76.2 x 50.8 x 24.0 mm form factor also helps in space-constrained electronics assemblies. The input range is 80-264VAC for broad AC compatibility.

Can the EPS-65S-15 power multiple 15V automation accessories from one supply?

It can support multiple 15VDC accessories on the same bus as long as the combined demand remains at or below 65.1W and 4.34A. This is useful for low- to moderate-power 15V control subsystems. All connected loads still need to be designed for constant-voltage 15V operation.

Is the EPS-65S-15 suitable for outdoor cabinets or unprotected environments?

The specs show an operating temperature range of -30C to +70C (with output derating at higher ambient temperatures per the derating curve), but no IP rating is listed. Because no IP rating is provided, the published data does not describe it as an exposed outdoor power supply. It is better suited to indoor equipment or protected housings that stay within -30C to +70C.

What are the main differences between the EPS-65S-15 and the other EPS-65S versions?

The EPS-65S family shown here includes 3.3V 33W 10A, 5V 50W 10A, 7.5V 60W 8A, 12V 65W 5.42A, 15V 65.1W 4.34A, 24V 65W 2.71A, and 48V 65.3W 1.36A. The EPS-65S-15 version is the 15V option and is rated for 65.1W with 4.34A output current. Selection across the family mainly comes down to matching the required output voltage and current.
