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-25D-30 for a 30V constant-current LED light fixture?

Yes, if the fixture is designed for constant-current operation at 0.84A and falls within the 16.5–30V constant-current range. This driver provides up to 25.2W at 30V, so the fixture load needs to stay within that output range.

Is this driver suitable for small outdoor signage lighting?

It can be suitable for outdoor signage lighting when the LED load requires constant current at 0.84A and operates within 16.5–30V. The IP67 rating supports wet and outdoor use, and the 25.2W maximum output sets the load limit.

Can I use this power supply for a dimmable architectural lighting application?

Yes, for dimmable constant-current architectural lighting that matches 0.84A output and a 16.5–30V load range. This model includes built-in 3 in 1 dimming and delivers up to 25.2W.

How much 30V LED strip can this driver run?

Size it by current and voltage rather than watts per meter: the driver supplies a constant 0.84A within a 16.5–30V constant current region, up to 25.2W total. The strip must be a constant-current load rated for 0.84A with an operating voltage within 16.5–30V; a constant-voltage 30V strip is not a match.

Can the LPF-25D-30 be used in wet or outdoor locations?

Yes, its IP67 rating suits wet and outdoor environments. It is specified for a case temperature (Tcase) of -35°C to +70°C with load derating at higher temperatures, so the installation conditions need to keep the case inside that range.
