DC250
DC Voltage Regulator
The Power-Tronics DC250 DC Voltage
Regulator is the latest upgrade for all Power-
Tronics DC and XR series DC voltage
regulators. The DC250 is also capable of
replacing other manufacturers' voltage
regulators or existing manually operated
controls!
The DC250 is a unique, DC Voltage Regulator
that is designed specifically for replacement of
vintage or obsolete DC generator voltage
regulation equipment such as manually operated
rheostats and/or resistor banks and offers
precise voltage regulation regardless of the
connected load and ambient temperature. The
DC250 is a ruggedized design and is engineered
to provide a lifetime of trouble-free operation.
PLC and automated control is possible with the
DC250 by simply adding an optional,
inexpensive digital interface module. This
capability makes the DC250 suitable for
automated or unattended installations.
Specifications
The DC250 DC Voltage Regulator has a unique
modular design to increase reliability and
facilitate repair should the need ever arise. The
DC250 is made up for separate control and firing
modules and contains a user-replaceable field
flashing relay. Because of its modular design,
the DC250 DC Voltage Regulator can be fitted
with rectifier modules of varying amperage
capacity from 10adc to 40adc to meet the needs
of a wide array of DC generators!
