Safety & Warnings
- DO NOT install with power applied to device. [⚠️]
- DO NOT expose the device to moisture. [?]
Operation
DALI Address
One DALI address for the 2-channel output is assigned automatically by the DALI Master controller. Please refer to user manuals of compatible DALI Masters for specific operations.
Push Dimmer Mode
When connected with an AC PUSH switch, the digital display will show "PD" (Push Dimmer Mode). Operations under Push Dimmer Mode are as follows:
- Click the button to switch ON/OFF [?].
- Press and hold the button to increase or decrease light intensity to the desired level and release it. Repeat the operation to adjust light intensity in the opposite direction. The dimming range is from 0.1% to 100%.
- Memory function after power off or power failure enables the device to memorize the status before power off when power on again. [?]
Wiring Diagrams
1. With DALI Bus
This diagram illustrates the connection of the DALI bus (DA, DA) and AC input (L, N) to the DALI Dimmable Driver. The driver then connects to the LED light via its LED OUTPUT terminals. The power source is 200-240V, 50/60Hz.
2. With PUSH Dimmer
This diagram shows the wiring for a PUSH dimmer setup. AC input (L, N) and an AC PUSH switch are connected to the DALI Dimmable Driver, which then powers the LED light through its LED OUTPUT terminals. The power source is 200-240V, 50/60Hz.
Dimensions
The driver has a circular form with a diameter of 57mm and a height of 24mm.
