LDC-80 series

80W Constant Power MODE Linear LED Driver

File Name:LDC-80-SPEC 2018-02-02

TEMPERATURE COMPENSATION OPERATION

LDC-80 have the built-in temperature compensation function ; by connecting a temperature sensor (NTC resistor) between the +NTC / -NTC

terminal of LDC-80 and the detecting point on the lighting system or the surrounding environment, output current of LDC-80 could be

correspondingly changed, based on the sensed temperature, to ensure the long life of LED.

◎ LDC-80 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 IADJ. pin

NTC reference:

NTC resistance

<17.5K

Output Current

Output current reduce as the resistance decreases

Notes: 1. MEAN WELL does not offer the NTC resistor and all the data above are measured by using resistor.

2. If new brand of NTC resistor is applied,please check the temperature curve first.

◎ Dimming function of the driver will be invalid when the "temperature compensation" function is in use.
