The VR6 voltage regulator is used on 4/6 and 10/12
lead self-excited generators and permanent magnet
generators, and also used on AREP generators. The
VR6 regulator is typically located in the generator
terminal box. The regulator may also be located in
the marshaling box. In some applications, the
regulator may be remotely mounted.
