1. All parameters NOT specially mentioned are measured at 230VAC input, rated and 25 of ambient temperature.current ℃

2. Please refer to " ".OUTPUT CURRENT SETTING

3. De rating may be needed under low input voltages. Please .- refer to STATIC CHARACTERISTIC sections for details

4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.

5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.

6. This series meets the typical life expectancy of >50000 hours of operation when Tcase, particularly point (or TMP, per DLC), is about 70 or less.℃tc

2. The output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.

3. To ensure the dimming performance at low dimming level,output current must be over 45mA.

◎ PUSH dimming(primary side)

Action FunctionAction duration

Short push 0.1~1 sec. Turn ON-OFF 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 LS terminal, as displayed in the diagram,

and AC/L (in brown or black); it will lead to short circuit if it is connected toAC/N.

TEMPERATURE COMPENSATION OPERATION

LDC-35 have the built-in temperature compensation function ; by connecting a temperature sensor (NTC resistor) between the +NTC / -NTC terminal of LDC-35 and the detecting point on the lighting system or the surrounding environment, output current of LDC-35 could be correspondingly changed, based on the sensed temperature, to ensure the long life of LED.

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.
