VMB4DC 4-channel dimmer controller module user manual – version 3 3
DESCRIPTION
The module features four 0/1 to 10V outputs. Each output can accept one or more DC-controlled power dimmers
so as to dim large groups of bulbs simultaneously.
The module also allows you to dim neon lighting equipped with a dimmable electronic starter with 1-10V control
input.
Controlling DC-controlled LED dimmers allows also an attractive ambient lighting.
Each channel can memorize several dimming functions and preset ambiances.
CHARACTERISTICS
Use:
• suitable for controlling DC-controlled power dimmers with 0/1-10V control input
• suitable for controlling DC-controlled LED dimmers with 0/1-10V control input
• suitable for dimming neon lighting equipped with a dimmable electronic starter with 1-10V control input
Outputs:
• 4 outputs with common (-) connection
• output voltage: 0 to 10V or 1 to 10V (adjustable per output)
• max. output current: 10mA per output
• the output is protected against short-circuits and overvoltage
• galvanic separation between the output voltage and the Velbus power supply (3000VDC isolation)
LED indications:
• status indication for all 4 channels
o continuously lit: selected dimming level achieved
o slow blinking: timer running
o fast blinking: changing dimming level
o two short blinks: communication error
• power voltage present
• data reception and transfer over the Velbus
• status notification of the dimmer to the control modules
