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

2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.

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

4. Efficiency is measured at 500mA/80V output set by DIP switch.

5. Current ripple is measured 50%~100% of maximum voltage under rated power delivery.

6. Standby power consumption is measured at 180~230VAC.

7. 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.

(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)

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. Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which

can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA2-type.

10. 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.

DIP SWITCH TABLE

LCM-40DA/DA2 is a multiple-stage constant current driver, selection of output current through DIP switch is exhibited below.

Note : For more current setting,please contact MW’s sales.

DIMMING OPERATION

PUSH dimming(primary side)

Action	Action duration	Function
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 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; for DA/DA2-Type)

Apply DALI signal between DA+ and DA-
DALI protocol comprises 16 groups and 64 addresses
First step is fixed at 6% of output.

SYNCHRONIZATION OPERATION

Synchronization up to 10 drivers (1 master + 9 slaves)
Dimming operating range: 10%~100%
Sync cable length: < 5m
Sync cable type: Flat cable
Sync cable cross-section area: 22 – 24 AWG (0.2~0.3mm2)

NOTE:

Please make sure all units are set to 100% dimming setting (factory default) before synchronizing.
Min. Dimming operating range depends on a dimmer setting.

TEMPERATURE COMPENSATION OPERATION

LCM-40DA/DA2 has the built-in temperature compensation function; by connecting a temperature sensor (NTC resistor) between the +NTC / -NTC terminal of LCM- 40DA/DA2 and the detecting point on the lighting system or the surrounding environment, the output current of LCM-40DA/DA2 could be correspondingly changed, based on the sensed temperature, to ensure the long life of LED.

LCM-40DA/DA2 can still be operated normally when the NTC resistor is not connected and the value of the output current will be the current level selected through the DIP switch.

NTC reference:

NTC resistance	Output Current
220K	< 60℃, 100% of the rated current (corresponds to the setting current

level)

60℃, output current begins to reduce, please refer to the curve for details.

330K| < 70℃, 100% of the rated current (corresponds to the setting current level)

70℃, output current begins to reduce, please refer to the curve for details.

470K| < 80℃, 100% of the rated current (corresponds to the setting current level)

80℃, output current begins to reduce, please refer to the curve for details.

Notes:

MEAN WELL does not offer the NTC resistor and all the data above are measured by using the THINKING TTC03 series.
If other brands of NTC resistors is applied, please check the temperature curve first.

Dimming and synchronization function of the driver will be invalid when the “temperature compensation” function is in use.
