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. The DA type power supply is less efficient than the typical efficiency in specification by 2%.
7. 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.

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.

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 75mA.

Every Long Push changes the dimming direction, dimming up or down
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)
