TEMPERATURE COMPENSATION OPERATION
LCM-40 have the built-in temperature compensation function (T ,Io ). By connecting a temperature sensor (NTC resistor) between the NTC +/-

terminal of LCM-40 and the detecting point on the lighting system or the surrounding environment, output current of LCM-40 could be
correspondingly changed to ensure the long life of LED.

Notes: 1. MW 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.

1.LCM-40 can still be operated well when the NTC resistor is not connected and the value of output current will be the current level that you set
through the DIP switch.
