VMB8DC-20 Constant current driver

Beste

Ik heb een installatie met stroom gestuurde spots. Ik zou deze willen dimmen via een 1-10V signaal naar mijn drive van de spots. Ik heb dit nog niet uitgeprobeerd, maar theoritische zou dit toch moeten lukken?

Is het mogelijk om dit te doen via de VMB8DC-20 (Achtkanaals 0/1-10V Universele Dimmer Controller). Als ik op de primaire kant van mijn drive 230V laat toekomen kan ik via de 1-10V signaal van de VMB8DC-20 de drive toch dimmen?

Ik heb dit nog niet uitgeprobeerd, maar theoritische zou dit toch moeten lukken?
Heeft er hier iemand ervaring mee?

Alvast bedankt.

Does this drawing help you??

Oh yes it does help me. Why do you use a realay swich for the 230v to the driver?

And does it works good in reality?

Good morning

Please excuse me replying in English.

That is totally optional , it’s only there to shutdown the power supply when not in use.

Yes, I use this with all our Constant Voltage LED installations.

However, I’ve never (personally) installed Constant Current LED.

This drawing was created for a Velbus forum user years ago who had the same issue.

Constant Current is a dark art that needs very careful consideration, which is why I encourage our customers to use Constant Voltage.

I think the short answer is,

In theory, yes. But it always depends on the calculations and quality of components

Thank you for the explanation!
The lights are continuous current drivers, we can’t longer change this (choice of the wife…). I would place the driver in my electrical cabinet. From there, start with 3g2.5mm2 to the lights. Distance is maximum 25 meters. Would this distance be too big? According to the “theoretical calculations” this would work, but theory and practice are a big difference…

In theory, as long as the current draw from the LEDs is limited.

It should be fine.

But…
