XR5C
Specialty Series
Universal Voltage Regulator
The Power-Tronics XR5C Universal Voltage
Regulator is the latest upgrade to the XR500C
product line and features a strengthened
regulation system and a redesigned rectifier
section to match that of the XR8! The XR5C is
also capable of replacing other manufacturers'
voltage regulators and has optional Static Exciter
Modules to boost its capacity to 30 amps DC!
The XR5C is designed for legacy installations and
specialty applications where tolerance to extreme
waveform distortion is required or installations
where manual tuning of stability is preferred.
Manual stability matching is sometimes required
on applications with severe waveform distortion
due to VFDs, solid-state drives, motor soft-start
systems, UPS loading, or generators with
extremely slow or non-linear magnetic
characteristics. Because the stability is matched
manually, the technician can tune the regulator to
the generating system, allowing the XR5C to
regulate loads that other types of automatic
voltage regulators cannot.
Like the XR500C, the XR5C 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. All
major electronic components are not
encapsulated to facilitate repair while all sensitive
components are encapsulated to protect them
from contamination and moisture.
PLC and automated Genset control is possible
with the XR5C by simply adding an optional,
inexpensive digital interface module. This
capability makes the XR5C suitable for automated
or unattended installations, or large-scale parallel
operations. The XR5C 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.
