Hi

I'm trying to find an off-the-shelf signal conditioner. It will have a control input voltage of 0-10VDC and the the output will be 0-24VDC 350mA.
The output will vary an electromagnet.

Many thanks for your Help.

 

What you describe is not a signal conditioner, it is a variable constant current source.

You say the input is 0-10V, is that the power source or a control voltage? Assuming the latter, what is the power source?

Here is what I think you are saying:

You want a voltage controlled constant current source that can output up to 350 mA with a compliance range of 0-24V and a control voltage of 0-10V to vary the current from 0 to 350 mA.

Obviously, you are not going to get 350 mA at 0V, so the compliance range is impossible.

You say it is to vary an electromagnet. How fast? What is the highest frequency of operation? What is the inductance of the electromagnet.

 

Thanks for your prompt reply.
Yes, the current go from 0 to 350mA.
At the moment the 24VDC electromagnet is being controlled via a pot on a control panel. We will be going to a radio-controlled
system where the only control voltage output we have is 0-10VDC available. There will be 24VDC available for the electromagnet itself. It's quite a basic set up so as long as we have the 0-24VDC this will control the electromagnet.

 

2. Does the magnet voltage have to go all the way down to 0.0 V, or can it bottom out at around 2 V?

3. Do you want to buy a power supply that will do what your want with a manufacturer's warranty and full safety certifications, or do you want to build one from scratch?
If you want to build this, it can be either a very basic linear power supply, or a PWM driver based on a motor controller module (Amazon, ebay, etc.)

How much current can the 0-10 V control voltage source supply?

This is just for magnet voltage control correct? The magnet has a separate supply for the coils?
