Description

LPF-25 series is a 25W AC/DC LED driver featuring the dual modes constant voltage and constant current output. LPF-25 operates from 90~305VAC and offers models with different rated voltage ranging between 12V and 54V. Thanks to the efficiency up to 87%, with the fanless design, the entire series is able to operate for -35°C ~ +70°C case temperature under free air convection. The entire series is rated with IP67 ingress protection level and is suitable to work for a variety of applications at dry, damp or wet locations.

PACKING| 0.36Kg; 40pcs/ 15.4Kg/1.02CUFT
NOTE|

All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
Please refer to “DRIVING METHODS OF LED MODULE”.
Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
Tolerance : includes set up tolerance, line regulation and load regulation.
De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
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.
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)
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.
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.
Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.com
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).
For any applica0tion note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
