CE ROHS listed Dali dimmer switch for led bulbs
The lamp with dimmer control within the effective distance, you can connect any receiver and keep the effects in sync. With dimming and switching functions.
1.Technical Parameters
2. Feature
1)DALI dimming way: dimming by broadcasting direct arc power level
2)Max output current:65mA DC .It could be connected 32 DALI drivers
if maximuin consumption current is 2mA of each driver.
3)Led indicator : When the dimmer is ON ,the led indicator is OFF.
When the dimmer is OFF ,the led indicatore is ON

5.Operation
Short press the dimmer is ON/OFF When the dimmer is ON ,long press the rotary key to dim the brightness up or down. When the dimmer is off ,long press the rotary key to turn on dimmer and dim the brightness as well. When the dimmer is ON ,rotate the rotary key to fine brightness..
6.Working Principle
1.AC Input directly and provide 65mA output current to the DALI signal line
2.With memory function, when power is on, it could automatically return to the state before power-off.
3.Add a power-off detection circuit, EEPROM could be done only if power failure , to avoid continuous
reading and writing EEPROM in order to extend the service life of the dimmer
7.Instruction manual
Qestion:
Output channel: 2 channel (diverse output dimming), why are some DALI dimmers set to 1 channel (one output dimming)?
Asswer:
Dali dimmer is a dimmer hanging on the dali bus. It is dimmed by transmitting digital signals. 1 channel, 2 channels, all of which have only 2 signal lines output, set 2 or 1 way. Just to meet different needs. The difference is that 1 channel can only control 1 device or control all devices through broadcast; 2 channels can control 2 devices, or control all devices through broadcast.
