I would like to inquire if a voltage regulator maybe used as a power supply to a system. I am not very familiar with EE stuffs so any help would be appreciated :) Our system consists of aluminum metal plates submerged in water. It needs to be supplied with 10A (DC) thru the portion of the plate that is not submerged. What I have is a voltage regulator with variable output. Its input is 220V and output maybe adjusted thru a knob from 0-250V and with maximum capacity of 12A. My question is that will it suffice to serve as our power supply? Would the output be DC or AC? And am I right to say that what we are supposed to do is to adjust the voltage output until the current read is 10A? Thanks in advance.
