I Just got Shane's PWM hooked up. The instructions say to turn the limit and duty pot's CCW all the way then to add Electrolyte till the target current is reached. Then adjust the limit pot CW till the current starts dropping and the same with the duty pot.
I added enough electrolyte to hit 30amps. I wanted to lower the current to about 20amps. I started to turn the limit pot CW, I had made a few turns to try and lower the current. While I was turning the pot CW, The current just stayed constant. Then I hit a point where the current started to rise. The power supply started to buzz when this happened. The more I turned it CW, the higher the current rised. Same with the duty pot.
The power supply is a Audio Authority 50amp continuous power supply. It's not a switching power supply. It weighs about 35lbs.
Anybody have any suggestions?
Thanks!
