This is the replacement of SIEMENS 6GA-2491.
Note that the inner design is completely different
from the original and has overcome all the
problems of original design. Overall its much
improved in every aspect. The build quality is
first class and practically it will never malfunction.

 

This is a subtractive regulator connected to a
compound circuit. This set up is adjusted to
provide a voltage higher than the rated voltage.
The purpose of this regulator is to shunt the
excess exciting current in order to maintain the
voltage at its rated value.
