NOTE|

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
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 tc point (or TMP, per DLC), is about 70℃ or less.
7.  Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.co
8.  The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
9. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently

connected to the mains.

OUTPUT CURRENT SETTING

• I-V Operating Area.

Output rated current level can be adjusted by a additive resistance.

Rated current setting table

Note:
output power≤35W
DIMMING OPERATION

• 3 in 1 dimming function(for B-Type)

• Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
  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.)

Applying additive 0 ~ 10VDC“DO NOT connect “DIM- to Vo-”

Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):
“DO NOT connect “DIM- to Vo-” Applying additive resistance:
“DO NOT connect “DIM- to Vo-”
Note :

1. Min. dimming level is about 8% and the output current is not defined when 0%< Iout<8%.
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.

DALI interface
PUSH dimming(primary side)

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 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.

NOTE:
DALI, Push dimming can not be used in the same time!(The factory setting defaults to DA)

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.

• LDC-35 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:

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.
