Description
The ABB DCF803-0035 3ADT209023R0001 Field Exciter is a half-controlled 3-phase converter for DC motor field excitation applications within the ABB DCS800 and DCS880 drive system families. The ABB DCF803-0035 is based on the SDCS-FEX-4 control board, which is equipped with its own synchronization and current control capabilities. The ABB DCF803-0035 features a current measurement circuit that is automatically scaled depending on the rated field current of the motor, ensuring optimal performance across a wide range of motor sizes.
The ABB DCF803-0035 accepts AC input voltages ranging from 110 V –15% to 500 V +10%, supporting both single-phase and 3-phase operation modes. For single-phase operation, terminals U and W are connected. The ABB DCF803-0035 provides a DC output current range from 0.3 A up to 35 A, with an AC input current that is less than the DC output current. The ABB DCF803-0035 operates at the same frequency as the DCS converter and features an AC isolation voltage of 600 V.

The power section consists of a three-phase half-controlled bridge with freewheeling diode. The unit accepts AC field supply voltages from 110 V to 500 V AC (3-phase), with a tolerance of −15% to +10%. In three-phase operation, the maximum DC output voltage is approximately 1.35 times the AC line voltage (minus tolerance). Single-phase operation is also supported using terminals U and W, though an autotransformer is recommended for voltage adaptation. In single-phase mode, the output voltage is approximately 0.9 times the line voltage.
The DCF803-0035 3ADT209023R0001 ABB Field exciter may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The field exciter is controlled by the SDCS-FEX-4 control board, which contains an H8 microcontroller for current control, synchronization, and fault handling. The board features two-channel actual field current measurement in the DC circuit, high-ohmic AC voltage measurement, and a CAN-based drive-to-drive communication interface. All control parameters, current references, and status monitoring are handled via the DCS link serial communication from the armature converter. The current measurement circuit includes an autoscaling function that automatically adjusts burden resistors based on the rated motor field current.
The unit requires an external 24 V DC auxiliary supply at 200 mA, typically provided by the armature converter. External line reactors and AC fuses must be installed by the user. For three-phase operation, line reactors KLR16BTB or KLR45CTB are used; for single-phase operation, reactor ND-30 is recommended. Semiconductor fuses (FWP series) sized according to the field current range protect the AC supply lines.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
AC Mains/Auxiliary Supply: The DCF803-0035 can be configured for single-phase or 3-phase AC supply up to 500 V. Connect the AC supply (usually through an autotransformer and line reactor to adjust voltage and reduce ripple) to terminals U1, V1, and W1.
DC Output (Field): Connect the motor field windings to terminals C1 (+) and D1 (-). Always verify that V ≈ 0 with a multimeter before touching these terminals.
Fuses: Use external semiconductor fuses on the AC line side to protect the thyristors (e.g., 50 A, 660 V UR fuses).
Technical notes
The ABB DCF803-0035 features an RS232 port used for downloading the Field exciter firmware package. The firmware download on the ABB DCF803-0035 is activated by setting S2:1-2 before the auxiliary voltage is switched ON, with field exciter mode set as S2:3-4 (default). The ABB DCF803-0035 requires an external line reactor for proper operation, with line fuses being external for the DCF803-0035 model. The power loss of the ABB DCF803-0035 is less than 130 W at rated current.
