## ※ **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.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →
Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
