Test conditions and notes12

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
7. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
9. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
11. 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).
12. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the LPF-25-12 for 12V LED strip lighting in a display or cabinet?

Yes, this model suits 12V lighting products that stay within its 25.2W maximum output. It provides 12V at 2.1A, which fits short 12V LED strip sections used in display, cabinet, or accent lighting. Check that the strip’s total load does not exceed 25.2W.

Is the LPF-25-12 suitable for 12V sign lighting?

It can be used for 12V sign lighting when the total demand is within 25.2W. The IP67 waterproof rating makes it suitable for signs in wet or dusty environments. Confirm the sign modules are rated for 12V and that the full load stays under 2.1A and 25.2W.

Can this driver power a short 12V under-shelf or accent lighting run?

Yes, for a short 12V lighting run that does not draw more than 25.2W. With 12V output and 2.1A current, it is intended for lower-power applications rather than long, high-load strip runs. Check the lighting product’s rated load before selecting it.

Is the LPF-25-12 okay for outdoor or damp locations?

Yes, it has an IP67 waterproof rating, so it is designed for wet and dusty conditions. Its working case temperature (Tcase) range is -35°C to +70°C, with load derating per the output load vs temperature curve, which supports use in a wide range of indoor and outdoor environments. The rest of the lighting system should also be rated for those conditions.

How many meters of 12V LED strip can the LPF-25-12 support?

Base the estimate on the 25.2W maximum output. Length = 25.2W divided by your strip’s rated watts per meter, so a 4.8W/m strip would be about 5.25 meters. Check your strip rated power per meter before sizing the run.

How does the LPF-25-12 compare with the other 25W LPF voltage options?

In the 25W LPF range, the standard versions are 12V 25.2W 2.1A, 15V 25.05W 1.67A, 20V 25W 1.25A, 24V 25.2W 1.05A, 30V 25.2W 0.84A, 36V 25.2W 0.7A, 42V 25.2W 0.6A, 48V 25.44W 0.53A, and 54V 25.38W 0.47A.
