Power supply using a voltage regulator?
Power supply using a voltage regulator?
(OP)
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.

Unless you are trying to electrolyse pure water I don't think you should need anything like 250V on the plates (added electrolytes or residual impurities will make the ionisation voltage much lower than 250V, therefore consider using an isolating transformer between the output of the variable transformer and the bridge rectifier suggested by Benta. This should preferably have a secondary voltage of 30V maximum to avoid a shock hazard to personnel but should still provide sufficient electrolysis current if your plates have sufficient surface area (but see your regulations for 'wet' areas).
