The Power-Tronics XC4 Automatic Voltage Regulator
is the latest upgrade for our commercial voltage
regulator product line! The XC4 is capable of replacing
other manufacturers' voltage regulators and can fit into
extremely tight enclosures due to its small size!
The XC4 is designed as a commercial product, ideal
for installation in standby applications, portable
generators, residential generators, and any application
where the customer demands a simple, reliable, and
durable regulator at a competitive price.
The Revision A XC4 offers greater value with an
onboard fuse to protect against overload or external
faults!
Simplicity and Reliability are important to the Power-
Tronics brand, and all components used in the
manufacture of our products are high-quality name-
brand and engineered to withstand the continuous
ratings advertised on our products. You can have
confidence with a product designed and manufactured
in the USA and backed by a factory One-Year
Warranty!
Based internally on the XR8 voltage regulator, the XC4
offers precise voltage regulation regardless of the
connected load and ambient temperature. It
incorporates an idle-protection circuit that automatically
reduces voltage to prevent excessive rotor heating
when the engine is idled.
The XC4 uses the XR8’s patented electronic circuitry
that automatically matches the regulator's response
time to the generator exciter. This greatly speeds
installation and eliminates guesswork. Because it only
uses 4 wires for connection to the generator, it also
makes quick replacement in the field possible!
To ensure extreme durability and dependability, the
XC4 is fully encapsulated in a heat-resistant polyester
resin. Because of its strong design and fully
encapsulated packaging, the XC4 is able to withstand
extreme operating conditions that would damage most
other voltage regulators.
The XC4 is a direct upgrade for previous VP4, VP5,
VR50, and VR250 voltage regulators.
