XR8
Professional Series
Universal Voltage Regulator
REVISION A (or later)
The Power-Tronics XR8 Universal Voltage
Regulator is the latest upgrade for all UVR and
XR series voltage regulators and features an
upgraded regulation system and a higher
amperage rectifier section capable of 8 amps!
The XR8 is also capable of replacing other
manufacturers' voltage regulators and has
optional Static Exciter Modules to boost its
capacity to 30 amps DC!
The XR8 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 XR8 is a ruggedized design
and is engineered to provide a lifetime of
trouble-free, reliable operation.
Manual stability matching is a thing of the past,
the XR8 contains patented electronic circuitry
that automatically matches the regulator's
response time to the generator exciter. This
greatly speeds installation and eliminates
guesswork.
PLC and automated Genset control is possible
with the XR8 by simply adding an optional,
inexpensive digital interface module. This
capability makes the XR8 suitable for automated
or unattended installations, or large-scale
parallel operations.
Like our previous models, the XR8 is fully
repairable! All major electronic components are
not encapsulated to facilitate repair while all
sensitive components are encapsulated to
protect them from contamination and moisture.
The XR8 is compatible with all previous and
current optional modules available for use with
Power-Tronics voltage regulators making it
extremely simple to upgrade an existing voltage
regulator installation.

    Introduction and Functional Description Caution: Read This Installation Manual Carefully and Entirely! Warning: Do not use digital equipment to read voltage, Hz, or amperage during this installation. Use only Analog sensing equipment! Failure to do so may result in damage to equipment or in personal injury! ALWAYS perform all setup procedures off-line ALWAYS wear eye protection...

  • Page 4: Determining Which Hookup Configuration To Use

    Determining Which Hookup Configuration to Use STOP! If you are using an optional SEM250A/B or SE350/450 Static Exciter Module, DO NOT use these instructions for hookup! See the instructions that came with your module instead! The XR8 Universal Voltage Regulator is configurable for 3 different output ranges suitable for use on the vast majority of generators available on the market from past and present.

  • Page 7: Use With Pmgs, Dpe, Aux, And Harmonic Winding Generators

    PMG, DPE Winding, Auxiliary Winding, and Harmonic/Resonant Winding Use The XR8 Universal Voltage Regulator is compatible with some of these types of generators but not others. It is necessary to determine which type of generator you have before proceeding since some styles will connect differently than others while the XR8 cannot be used with some of these generators at all.

  • Page 8: Hookup Connection A

    240V @ 10A NOTE: It is not necessary to jumper terminals 7 and 8 if not using XR8 Professional Series the Remote Voltage Universal Voltage Regulator Adjustment! NOTE: If the generator is to be operated below 50/60 Hz, a disconnect or switch should be installed in series with the incoming power to terminals #1 and #2 on the XR8.

  • Page 9: Parallel Configuration For Connection A

    Connection A. NOTE: Power-Tronics products parallel using the Reactive Droop compensation method. This allows our products to parallel with existing systems easily while also allowing islanded operation with the flip of a switch. When initially installing the droop resistor, set it for approximately 7Ω before final adjustment later. If the droop is excessive when load testing, reduce the resistance a bit at a time until satisfactory droop is achieved.
