DIMMING OPERATION AC/L AC/N FG DA;AC/N DA;AC/L 3 in 1 dimming function(for BType) Output constant current level can be adjusted by applying one of the three methodologies between and : 0 ~ 10VDC, or 10V PWM signal or resistance. Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers. Dimming source current from power supply: 100μA (typ.)

DIMMING OPERATION Push Button AC/L AC/N AC/L AC/N FG DA;AC/N DA;AC/L DMIN DMIN DALI interface PUSH dimming(primary side) Action Action duration Function Short push 0.1~1 sec. Turn ONOFF the driver Long push 1.5~10 sec. Every Long Push changes the dimming direction, dimming up or down Reset >11 sec. Set up the dimming level to 100% The factory default dimming level is at 100%. If the push action lasts less than 0.05 sec., it will not lead to a change for the status of the driver. Up to 10 drivers can perform the PUSH dimming at the same time when utilizing one common push button. The maximum length of the cable from the push button to the last driver is 20 meters. The additive push button can be connected only between the PUSH terminal, as displayed in the diagram, and AC/L (in brown or black); it will lead to short circuit if it is connected to AC/N. DALI interface(primary side) Apply DALI signal between DA and DA DALI protocol comprises 16 groups and 64 addresses. First step is fixed at 8% of rated output power. DALI, Push dimming and 2 in 1 dimming can not be used in the same time!(the factory setting defaults to DA)
TEMPERATURE COMPENSATION OPERATION LDC55 have the builtin temperature compensation function ; by connecting a temperature sensor ( terminal) between the / terminal of LDC55 and the detecting point on the lighting system or the surrounding environment, output current of LDC55 could be correspondingly changed, based on the sensed temperature, to ensure the long life of LED. resistor LDC55 can still be operated normally when the resistor is not connected and the value of output current will be the current level selected through the. pin reference: resistance Output Current 33K <33K, output current begins to reduce Notes: 1. MEAN WELL does not offer the resistor and all the data above are measured by using resistor. 2. If other brands of 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.
