Direct Replacement for the Marathon PM300
The SS300 voltage regulator is an encapsulated electronic voltage regulator which controls the output of a brushless AC generator by regulating the current into the exciter field.
The ADVR-073 is an advance (Hybrid Analog/Digital Voltage Regulator) design for general-purpose isochronous applications. The ADVR-073 uses an reliable CPU (Central Processing Unit) in its design. This eliminates complex analogue components and circuits that are inherently over sensitive to temperature eliminating voltage instabilities and drift. In addition, we added over excitation and loss of sensing shutdown protections, with matching U/F, O/E LED indicator lights. Consequently, this AVR prevents the generator from excitation overload, preventing exciter and regulator damage. It is easy to install and flexible for use in both shunt type and generators with auxiliary windings.
Replaces Marathon DVR-2000 SeriesADVR-2200M is an Digital/Analog hybrid voltage regulator that substitutes certain Marathon DVR applications. This regulator can work with either single or three phase sensing and PMG. The ADVR-2200M as protection against over excitation, as well PF (power factor) correction inputs. And also as capabilities for DROOP Parrelleling.
