DCF803-0050, DCF804-0050, DCF803-0060 and DCF804-0060
DCF803-0050 / 0060 and DCF804-0050 / 0060 are external single-phase field converters. 
The half controlled (1-Q) field exciters DCF803-0050 / DCF803-0060 include the SDCS-FEX-82, 
two thyristor/diode power modules and auxiliaries (power supply, line reactor L1). 
The full controlled (4-Q) field exciters DCF804-0050 / DCF804-0060 include the SDCS-FEX-81, 
four anti-parallel thyristor power modules and auxiliaries (power supply, line reactor L1).
The control structure is similar to the SDCS-FEX-4 in single-phase operation. A micro controller is 
used for controlling the field current and firing. The DC current is measured using an AC current 
transformer.
