Test conditions and notes10

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Peak current or peak power up to 3 seconds is provided.
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. Line regulation is measured from low line to high line at rated load.
6. Load regulation is measured from 0% to 100% rated load.
7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
8. Derating may be needed under low input voltages. Please check the derating curve for more details.
9. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the 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 )
10. 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

What is the output rating of the Mean Well ENP-120-12?

The ENP-120-12 is rated for 120W output at 13.8V DC and 8.7A. This makes it suitable for applications that need a regulated 13.8V desktop power supply with moderate current capacity.

What type of applications is the ENP-120-12 best suited for?

This model is designed as a desktop type AC/DC power supply for equipment that requires a 13.8V DC output. It is generally a fit for industrial, commercial, and battery charging use cases where an enclosed external supply is preferred.

Can the ENP-120-12 operate in demanding temperature conditions?

Yes. The specified working temperature range is -30°C to +70°C, which supports use in a wide range of operating environments. Output derating applies at higher ambient temperatures, so refer to the datasheet's derating curve.

What protections are built into the ENP-120-12?

The ENP-120-12 includes protection for short circuit, overload, over voltage, and over temperature. Its overload protection is specified at 110% to 125% with constant current limiting and auto-recovery.

How energy efficient is the ENP-120-12?

This model meets Energy Efficiency Level VI and has no-load power consumption below 0.15W. Its typical efficiency is 89.5%.

What input range does the ENP-120-12 support?

The ENP-120-12 supports universal input from 90 to 264VAC, and it also accepts 127 to 370VDC. That wide input range makes it easier to use across regions and power systems without needing a different model for standard mains variations.
