XR500B
Universal Voltage Regulator
The XR500B is a unique voltage
regulator that is designed specifically
for Professional Electrical Generator
Service and Repair Technicians.
The XR500B incorporates patented
electronic circuitry that allows an
installer to match the regulator to many
differing configurations of exciters
without special transformers or inline
resistors.
The XR500B can be externally
controlled with a PLC or Genset
controller by simply adding an optional
interface module.
