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 700mA/72V 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.
6. It is measured 60%~100% of maximum voltage under rated power delivery.

※
3 in 1 dimming function
Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal or resistance. For optional EO model, the 3 in 1 dimming is via SYNC+ and SYNC-(CN100 or CN101 connector).
Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.

:
Please make sure all units are set to 100% dimming setting(factory default) before synchronizing.
For optional EO model: the master is EO and the salve could be standard model for economic arrangement.
TEMPERATURE COMPENSATION OPERATION
LCM-40U have the built-in temperature compensation function ; by connecting a temperature sensor (NTC resistor) between the
+NTC / -NTC
terminal of LCM-40U and the detecting point on the lighting system or the surrounding environment, output current of LCM-40U could be
correspondingly changed, based on the sensed temperature, to ensure the long life of LED.
