Dimming actuator for LED sources, 3-channel DCDA-33M
For dimming LED and RGB sources 12-24 V DC by alternating current
DCDA-33M is a dimming unit designed to dim single-color and RGB LED light sources controlled by variable current.
The actuator has three independent channels and each output channel is individually addressable and controllable.
DCDA-33M actuator can be controlled from the BUS, DALI or DMX.
When controlling the unit from the BUSes and DMX, also the fourth virtual channel can be supported to control overall brightness (BUS – set in iDM3, DMX – set by long press of the PRG button).
DCDA-33M can directly control from the system iNELS where the communication interface is the installation BUS.
If for controlling, a communication interface DALI or DMX is used, it is possible to use the master unit EMDC-64M.
The supply voltage of the dimming unit must be at least 4V higher than the expected output voltage on the load.
Setting the communication interface and addresses of actuators is performed using DIP switches:
a) switch No. 1
- In the upper position determines DALI or BUS
- In the lower position determines DMX
b ) switch No. 2 (if that switch 1 is in the upper position)
- In the upper position determines DALI
- In the lower position determines BUS
Using the control buttons on the front panel, you can manually control the output.
The input circuits of communication interfaces are optically isolated from the supply voltage connected lamp unit, and is therefore resistant to electromagnetic interference.
DCDA-33M in 3-module is designed for panel mounting on DIN rail EN60715.
