![]() R4 and R5 is supposed to be the voltage divider in the 180A sensor. Part 2 is supposed to be the Sparkfun 180A current and voltage sensor. I couldn’t find all the right parts in Fritzing. My project idea is to use this to load test various sized batteries. can I use a low-pass RC filter between the optocoupeler, and the 2N3055 base to remove the ripple? Now, using PWM will chop the current draw, and this will reflect on the current and voltage sense, I assume. and using an “AttoPilot Voltage and Current Sense Breakout - 180A” from Sparkfun to sense current and voltage. I was planning on regulating the current with PWM from an Arduino. now, I have some 2N3055 power transistors, and to drive them, I was thinking I could use a Darlington optocoupeler (4N33, because I have some) to provide the load control. Ok, I have browsed for one on the internet that is higher current (15A or more), and I found THIS.
