TEMPERATURE COMPENSATION OPERATION

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

terminal of LCM-40DA and the detecting point on the lighting system or the surrounding environment, output current of LCM-40DAcould be

correspondingly changed to ensure the long life of LED.

> 60 , output current begin to reduce, details please refer to the curve.℃

> 70 , output current begin to reduce, details please refer to the curve.℃

> 80 , output current begin to reduce, details please refer to the curve.℃

3. Synchronization function of the power supply will be invalid when the "temperature compensation" function is in use.

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-40DA 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.
