How to Interface PIC 0-5V Output to Control 0-60V 3A Power Supply for Magnet Load

Hi friends.

I think I should give more detailed information. What I need is to use a PIC microcontroller, so using 2 push-buttons, I can increase/decrease the voltage level from 0 VDC to 60 VDC. The PIC output range is 0-5 VDC, so I need an interface to convert this signal to 0-60 VDC. Current output needed 2.5 or 3 A. Load is a magnet, with the following voltage/current measured:
* 40 V - 2.08 A
* 34.8 V - 1.85 A
* 30.3 V - 1.26 A
* 24.5 V - 0.69 A
* 18.4 V - 0.12 A
* 17 V - 0.01 A

The idea is to replace actual boards to get 50 or 60VDC in order to achieve a stronger magnetic force.


Thanks!

Best regards.

David, an off-the-shelf power supply that does what you want can be purchased for under $1000. The Acopian Y060LXB750 is such a power supply.

Using this is simple. Plug the power supply into AC power and connect the output to your electromagnet. Then drive the power supply 0-5 volt control input with your signal and it will output 0-60 volts.
