can the profilux 3 control a dimmable ballast for metal halides?

I didnt know what to ask for with regards to dimming

Search for

connector for external control 0-100% (maybe not possible for your lamps, so 50-100% is an alternative)
controllable via 1-10V signal (or any other voltage signal equivalent to the light output)
controllable via DALI

Hello.

Do you know if the dimmer for these ballasts are externally controllable? I would like to use them with a Profilux computer.

Thank you.

Simon.

they said....

"Yes, it is the same ballast ATI comes with and you control them with any 0-10v potentiometer.

so i think i have found it....

just confirming now....

This is the it...!

"The ballast does not come with the dimmer, you need a 0-10V dimmer or the profilux will also dim 0-10v"

So it seems i have found it.....

How do i get the Profilux to control them?

I was thinking of a seperate DPAB to control just the lights and programming the DPAB from there.

Is that right?

Thank you.

In general the Profilux has 1-10V outputs - you need a LBF-AP from GHL to connect it.

But ... it looks dimable, but there is a knob, no connectors for the 1-10V signaling. I would recommend to ask the guys for a wiring sheet before you order. If they haven´t one - forget it!
