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-12 for a 12V PLC, HMI, or industrial control panel?
It can fit 12V industrial control equipment that requires constant-voltage 12VDC and stays within the unit's 65W and 5.42A output. The wide 80-264VAC input also makes it suitable for panels used in different AC supply regions. Check that the total 12V load does not exceed 65W.
Is the EPS-65S-12 suitable for embedded 12V electronics or edge devices inside a compact enclosure?
This model is often a fit for embedded or IT equipment that needs regulated 12VDC and draws up to 5.42A. Its 76.2 x 50.8 x 24.0 mm size and 0.11 kg weight make it easier to use where board space is limited. It is a constant-voltage supply, so it suits 12V loads rather than constant-current applications.
Can I use the EPS-65S-12 for 12V sensors, relays, and automation accessories on one DC bus?
Yes, if the connected devices all require 12V constant-voltage power and their combined draw stays within 65W or 5.42A. That makes it relevant for grouped 12V automation loads such as control accessories and low-power subsystems. It is not the right choice for equipment that requires a different output voltage.
Is the EPS-65S-12 meant for outdoor use or harsh ambient conditions?
The provided specs list an operating temperature range of -30C to +70C (with output derating at higher ambient temperatures per the derating curve), but they do not list an IP rating. Without an IP rating in the published specs, it should not be treated as an outdoor-rated exposed power supply. It is better aligned with indoor equipment or protected enclosures where temperature still stays within -30C to +70C.
How does the EPS-65S-12 compare with the other EPS-65S models?
Within the EPS-65S group, the listed variants are 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-12 sits in the middle of the voltage range and provides 12V at up to 5.42A. All are compact EPS-65S open-frame models, but the output voltage, wattage, and current differ by SKU.

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.
