XR500D
Universal Voltage Regulator
The Power-Tronics XR500D Universal Voltage
Regulator is the latest upgrade for all UVR and
XR series voltage regulators. The XR500D is
also capable of replacing other manufacturers'
voltage regulators and has optional Static
Exciter Modules to boost its capacity to 30 amps
DC!
The XR500D is a unique, Universal voltage
regulator that is designed specifically for
Professional Electrical Generator Service
Technicians and the Electrical Generator Repair
Industry. It incorporates an easily selectable
frequency range for voltage roll-off during under-
frequency operation and offers precise voltage
regulation regardless of the connected load and
ambient temperature. The XR500D is a
ruggedized design and is engineered to provide
a lifetime of trouble-free operation.
The XR500D contains patented electronic
circuitry that automatically matches the
regulator's response time to the generator
exciter. This unique innovation eliminates the
need to manually adjust stability when setting up
the voltage regulator and greatly simplifies
installation.
Specifications
PLC and automated Genset control is possible
with the XR500D by simply adding an optional,
inexpensive digital interface module. This
capability makes the XR500D suitable for
automated or unattended installations, or large-
scale parallel operations.
