DCF 503A
• Half controlled thyristor/diode bridge (1-Q).
• Microprocessor control with the control electronics
being supplied separately (115...230 V/1-ph).
• Construction and components have been designed
for an insulation voltage of 690 V AC.
• Output voltage U

DCF 504A
• Fully controlled antiparallel thyristor bridges (4-Q).
• With this unit fast response excitation / de-excita-
tion and field reversal is possible. For fast response
excitation an appropriate voltage reserve is neces-
sary.
In steady-state condition, the fully controlled bridge
runs in half controlled mode to keep the voltage
ripple as low as possible. With a fast changing field
current, the bridge runs in fully controlled mode.
• Same design as DCF 503A
DCF 600
This field power converter is used mainly for armature
converters with rated currents of 2050 to 5200 A. It is
a modified armature circuit converter.

• The three-phase field supply converters DCF 600
needs a separate active overvoltage protection unit
DCF 506 for protecting the power part against too
high voltages.
The overvoltage protection unit DCF 506 is suitable
for 2-Q converters DCF 601 and for 4-Q converters
DCF 602.
