A plating rectifier turns mains AC into the smooth, controllable DC that an electroplating bath needs. How smooth matters: ripple on the output shows up as variation in the deposit, and variation in the deposit is a rejected part.
We build these on the same IGBT switching technology as our induction power supplies. High frequency switching allows a far smaller transformer than a conventional design, which is why the units are compact and light enough to be moved and re-sited as a plating line is rearranged.
They are air cooled. That is the practical difference from the oil-cooled rectifiers still common in Indian plating shops: no water circuit to plumb, no oil to change, no cooling infrastructure to maintain, and nothing to leak into a plating hall.
Our range starts at 12 V 300 A and runs to 12 V 10,000 A, with 18 V and 24 V ranges also available.

Questions engineers ask
Why does ripple matter in plating?
Deposition rate follows current. If the current ripples, the deposit grows unevenly, and on a bright or decorative finish that shows. Low ripple DC gives a more uniform, more consistent coating, which is why it is specified rather than assumed.
Air cooled or oil cooled?
Air cooled units need no water circuit, no oil, and no cooling infrastructure. They are smaller and lighter for the same output because high frequency switching allows a much smaller transformer. Oil cooled rectifiers remain common, but they carry maintenance and siting constraints that air cooled units do not.
What do you need to know to size a rectifier for my bath?
The plating process, the bath voltage, the peak current your work load draws, whether you need periodic reverse or pulse, and the duty cycle. Send us those details so we can recommend a suitable configuration.
