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-3.3 for 3.3V logic boards, embedded controllers, or SBC-based equipment?
It is designed for constant-voltage 3.3VDC output and can provide up to 33W or 10A. That makes it relevant for embedded electronics, digital logic platforms, and control boards that are built around a 3.3V rail. Verify the total 3.3V load stays within 10A.
Is the EPS-65S-3.3 suitable for supplying a high-current 3.3V rail in industrial electronics?
Yes. It shares the highest current rating in the EPS-65S series with the 5V model, providing 10A at 3.3V. That can fit industrial electronics or automation subsystems that need a substantial regulated 3.3V bus. Its total output is limited to 33W, so check both current and wattage.
Can the EPS-65S-3.3 be used for test benches or development fixtures that run on 3.3V?
It can fit bench or fixture use where the DUTs require a stable 3.3V constant-voltage supply and the load remains within 33W. The 80-264VAC input range is also practical for broad mains compatibility. Its compact 76.2 x 50.8 x 24.0 mm size helps in dense equipment builds.
Is the EPS-65S-3.3 rated for outdoor exposure?
The operating temperature range is -30C to +70C (with output derating at higher ambient temperatures per the derating curve), but no IP rating is shown in the provided specs. Without an IP rating, the published data does not indicate outdoor-exposed use. It is better treated as a supply for indoor systems or protected enclosures operating within -30C to +70C.
What are the differences between the EPS-65S-3.3 and the other EPS-65S models?
The EPS-65S family listed 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-3.3 is the lowest-voltage version and is rated at 33W with 10A output current. Compared with the higher-voltage models, it emphasizes current at a much lower output voltage.

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.
