VMBDMI - Single channel triac dimmer for resistive and inductive loads

1-channel 400W dimmer. Create an atmosphere which suits you best or let your lights dim slowly to avoid unexpected surprises. It is also possible to simulate a sunrise which makes waking up a lot more pleasant!

Q. Light switched at 100% during the day and 25% at night
A. A light needs to be switched at full intensity during the day (07:00 - 23:00), but at night (23:00 - 07:00) at a dimvalue of 25%. How to program this in Velbuslink? Read more ... (PDF)
Q. How can I make a motion detector set a light to a certain dim value during a certain time?
A. A Velbus motion sensor needs to turn a light on at a certain dim value (eg. 50%) during a certain time (eg. 1 minute).
This can be done as follows:
- in the configuration of the Velbus motion sensor module, set the timeout of the motion output to 1s
- create an action "Set to percentage" with the motion output channel as initiator and the dimmer channel as subject. Set the dim percentage parameter (in our example 50%). This action has also a "duration" parameter. Set this to the desired on time (in our example 1 minute)
