Wiring up a Digital V/A meter

Post by **Buick Mackane** » 22 Mar 2022, 22:31

I have two of these meters, Both the same as the model pictured below. (DSN-VC288) A few years back i tried to hook one up to my server supply but could only manage to get a voltage reading, No current reading, Recently dug out my converted sever PSU and would like to have another go at getting these meters up & running,

They have a 10 amp built in shunt but i want to use my external shunt which is rated at 50 amps (I think) So does anybody know how these should be wired with an external shunt ?

Cheers lemmy i was just looking at that diagram. Problem is the actual power for the meter and the power i want to monitor are all from the same power supply, And that seems to be an issue with this particular meter.

Hard to say. Test it with car lightbulb as load maybe?

Don't have one, I'll have a play around with it and see how it goes,
