• Description: 40W Multiple-Stage Output Current LED Power Supply
• Manufacturer: MEANWELL [Mean Well Enterprises Co., Ltd.]

TEMPERATURE COMPENSATION OPERATION
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.
1.LCM-40 can still be operated well when the NTC resistor is not connected and the value of output current is set by user Via the DIP switch.
2.
LCM-40 have the built-in temperature compensation function
NTC resistance
Notes: 1. MW does not offer the NTC resistor and all the data above are measured by using THINKING TTC03 series.
