TEMPERATURE COMPENSATION OPERATION
LCM-60U have the built-in temperature compensation function ; by connecting a temperature sensor (NTC resistor) between the +NTC / -NTC
terminal of LCM-60U and the detecting point on the lighting system or the surrounding environment, output current of LCM-60U could be
correspondingly changed, based on the sensed temperature, to ensure the long life of LED.

◎ Dimming and synchronization function of the driver will be invalid when the "temperature compensation" function is in use.
Notes: 1. MEAN WELL does not offer the NTC resistor and all the data above are measured by using THINKING TTC03 series.
2. If other brands of NTC resistor is applied,please check the temperature curve first.

◎ LCM-60U can still be operated normally when the NTC resistor is not connected and the value of output current will be the current level selected
through the DIP switch.
