Is 1-10V dimming same as 0-10V dimming?

I don't think so but I would like to ask you guys for more precise answer.
I got a driver from Europe that has a (I think) potentiometer attached with 2 conductors. I need to dimm the driver with control 4 Panelized lighting system and gotta coordinate it with AV guy who thinks 1-10 is the same as 0-10.
Please help.
Thank you.
 
0-10 and 1-10 are definitely not the same system and are not directly compatible.

Among other things, the voltage value that corresponds to full light intensity is opposite in the two systems.

A simple attached potentiometer (actually variable resistor if only two wire) could be part of the trigger threshold circuit for a phase controlled dimmer, which would be line voltage AC rather than either 1-10 or 0-10V.

Where do you get that from?

With standard 0-10V, I assume 10V is full brightness. Am I wrong?
They say anything less than 1V gives no light output. Seems like that would match.

I'm not sure this would be a problem anyway - the lighting system may have some way to invert the output, or some way to program it for an inverted output.

here is the driver

It might work, but I wouldn't make any guarantee's. Tell the AV guy its his baby if the smoke comes rolling out when its connected.

The difference between 0-10 volts and 1-10 volts doesn't worry me. 1-10 volts just means the lights will dim a little faster. When the lighting control panels turns the lights down to 10%, they will go completely out. Then nothing will else will happen between 10% and 0%.

What does worry me is a possible difference in the amount of current that flows in the two systems.

And also a possible difference in which device provides the voltage. Does the driver provide the voltage in both systems, or in 0-10 volt systems, do the lighting controls typically provide the voltage? I'm not sure because that's the type of thing I don't need to know when everything is standard 0-10V.

Again, I wouldn't make any guarantees, but there is a chance the AV guy has done this before, and there is a chance it could work.

Impressive statement.
Can I hear from anybody a definite that connecting 0-10V dimmer or module won't work with this 1-10 driver? And it may be dangerous?
Did anybody here work before with this system?

darekelec:

Why don't you experiment and determine the characteristics of the 0-10 or 1-10 ciircuit?

Apparently you are using the variable resistor to control the dimmer.

Before starting the following make sure the dimmer control is isolated from the AC line. If not don't proceed.

1. What is the maximum resistance, and the minimum resistance?
2. What is the open circuit voltage of the dimmer input (the resistor disconnected)?
Next connect the variable resistor.
3. With the resistance maximum what is the dimmer input voltage?
Is brightness maximum or minimum?
4. With the resistance minimum what is the dimmer input voltage?
Is brightness maximum or minimum?

5. Using the measurement from 3 and the known resistance calculate the input
current. What is its value?
6. Set the resistance at 1/2 its maximum value and calculate the current? What is it?
7. Connect a 10 ohm resistor to the dimmer control input terminals and measure the
voltage across the 10 ohm. What is it?

This information will then allow us to determine your next tests.
