Description
LPF-40 series is a 40W AC/DCLED driver featuring the dual modes constant voltage and constant current output. LPF-40 operates from 90 305VAC and offers models with different rated voltage ranging between 12V and 54V. Thanks to the hign efficiency up to 90%, with the fanless design, the entire series is able to operate for -40C~ +80’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.

| Note: | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25 C 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 teminated 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 ONOFF 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. 3. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without pemanently connected to the mains. 9. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly t point (or TMP, per DLC), is about 75C or less. 10. Please refer to the warranty statement on MEAN WELLs website at http://www.meanwell.com 11. The ambient temperature derating of 3.5 C/1000m with fanless models and of 5 C/1000m with fan models for operating altitude higher than 2000m(6500f). 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 xProduct Liability Disclaimer: For detailed information please refer to https://www.meanwell.com/serviceDisclaimer.aspx | |||||||||
