Yes.
That may explain why some of your current measurements seem odd.

In regards to the voltage measurement at the reactor, any measurement after the PWM will be the average voltage and can't be used to calculate gap voltage. You should always use the power supply voltage divided by the number of gaps in one stack.


It sounds like you are still putting too much load on the power supply.
Could you please dilute your electrolyte solution by pouring out half of it and topping off with distilled water. You can increase the concentration again later, when you can measure DC amps accurately, if necessary.
