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/50V output set by DIP switch.

5. Standby power consumption is measured at 230VAC.

6. 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)

7. 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).

8. 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.

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.

DIP SWITCH TABLE

LCM-25DA/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)

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 (0.2~0.3mm*)

• CN100, CN101: used to synchronously control the LCM units in parallel.

NOTE

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