UVR500 Universal Voltage Regulator - Power

advertisement
The UVR500 voltage
regulator is designed as a
universal voltage regulator for
replacement of most voltage
regulators found in the
international generator
industry. The installer can
select from a full range of
input and output voltages
limited only by the system
amperage. Optional static
exciter modules can be used
with this regulator to increase
the output amperage up to
300 amps. The UVR500
replaces all previous models of
Power-Tronics’ regulators
and can be altered to be used
as an ac phase control in
applications such as heating
controls, synchronous motors
and eddy current clutches.
