Overview
LCM-40U is the model of this series: rated power 35W, typical efficiency 87.5%.
LCM-40U series is a 35W LED AC/DC constant current mode output LED driver featuring the multiple levels selectable by dip switch. LCM-40U operates from 90～132VAC and offers different current levels ranging between 350mA and 1050mA. Thanks to the efficiency up to 87.5%, with the fanless design, the entire series is able to operate for -30℃~+90℃ case temperature under free air convection. LCM-40U is equipped with various functions, such as the dimming function and synchronization, so as to provide the optimal design flexibility for LED lighting system.

Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 115VAC input, rated current and 25℃ of ambient temperature.
- 2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
- 3. 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.
- 4. Efficiency is measured at 500mA/70V output set by DIP switch.
- 5. 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)
- 6. It is measured 50%~100% of maximum voltage under rated power delivery.
- 7. 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).
