Electrophoretic primer application
Electrophoretic primer application
(OP)
Hello,
I am totally lost here. I have long experience with controlled rectifiers for drives and welders, but absolutely none with rectifiers for electrophoresis.
I have been asked to check out the performance of one rectifier and the specifications seem to be something like 160 V and about 800 A. My question is: What is important? Voltage and/or current regulation? Normal tolerances allowed? Voltage ripple? What limits are used? Other things to look for?
The manufacturer closed down his operations many years ago and there seems to be very little suppport for this equipment. So any tips or links are welcome.

RE: Electrophoretic primer application
That is exactly what I was looking for.
Two questions: The rectifier ripple is said to be kept below five percent. Is this voltage or current ripple? Also pertaining to ripple: Is it the ripple inherent in the rectifier one is talking about (it cannot easily be influenced) or is it a low frequency ripple - such as the "waviness" that can be the result of a badly tuned controller?
