A variable voltage D. C. source is required
for the Electrodeposition process of electroplating, anodizing etc. The various
ratings of voltages and currents required for the process depends upon the metal
to be deposited and the process adopted. VOLTAMP Rectifiers are designed in
standard voltages of 8 V to 24 V, and in current ratings varying from 100 Amps
up to 10000 Amps.
