Hi, I have been following the YouTube video about adapting/modifying an ATX computer power supply to provide a 12 volt DC supply to a hot wire cutter for cutting shapes etc; out of XPS foam.
The module works so well that the cutting wire glows white hot when the power supply is switched on from the ATX at the full 12 volt output. The wire is therefore far to hot .
I have a Mini DC Motor Speed Control Driver Board 3V-35V 5A PWM Controller installed which varies the output successfully, but I would like to wire in dsn-vc288 volt meter and ammeter which I have but cannot seem to get the connections correct so that the outgoing volts and amps are shown on the meter so that I can reduce the output and control the temperature of the cutting wire.
The wiring instructions for the dsn-vc288 appear to be confusing to me.
I very much a newbie and would appreciate it if someone could give me a sketch wiring diagram using these components to control the setup?
I am not an electronics engineer, but a HEVAC engineer, so have no background in electronics.
I hope someone will help me out?
Many thanks for any help.

The wiring instructions for the dsn-vc288 appear to be confusing to me.
There are a few variations of the product on the market. I found this tutorial that looks like they included all the types. how-to-wire-digital-dual-display-volt-and-ammeter
I hope that helps. If not then include a description of what wires(size and color).
Also, sometimes these are off and need to be adjusted so check to make sure you have the correct readings.

I have attached the wiring schematic for my bench power ATX conversion.
hope this helps!

Many thanks Mel & Madmisha for the info. Found it very useful and should enable me to sort the connections out.
