DP832a tracking issue?
« on: April 21, 2020, 03:10:36 pm »
hi all.

curious one, i am trying to get 42v out of my psu to charge a 10s li-ion pack, set both at 21v each at 2amps. turned tracking on for both of them, and channel one is in cc mode yet ch2 is in cv mode.
any way i can get them to both output the same voltages and stay in cc mode untill the voltage has risen too 42v then both channels fall into cv mode?

cheers

You need to put the 2 channels in series. Just set them both to 21V, tie ch1 - to ch2 + and use ch1+ and ch2 - as your connections. This battery has builtin protection?

That's not really an issue. As your current drawn comes under the limit the voltage on ch1 will come up. At any given time you'll still get xx volts even if it looks odd with 1 channel at max and the other down.

Wow, that's weird. I would have asked the same question.
If at first you don't succeed, get a bigger hammer
