VMB4DC 4-channel dimmer controller module user manual – version 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:
