ABB SDCS-FEX-1 3ADT306000R1 Field Excitation Board

FAQ – Frequently Asked Questions

Q1: What is the function of the SDCS-FEX-1 board?
A1: It serves as a single-phase diode rectifier to supply field current for DC motors in DCS 500 systems.

Q2: What is the maximum AC voltage the board can handle?
A2: The board can operate with AC input voltages from 110 V (-15%) up to 500 V (+10%).

Q3: How is the board mounted?
A3: It must be installed inside the armature converter module and mechanically fixed beside the SDCS-POW-1 unit.

Q4: What is the board’s method for adjusting field current?
A4: Field current can be slightly adjusted using an external resistor in series with the field winding.

Q5: What does the board’s power loss look like under rated conditions?
A5: The power loss at rated DC output current is less than or equal to 10 W.

Q6: Is the SDCS-FEX-1 compatible with 690 V transformers?
A6: No, the board is rated for a maximum isolation voltage of 600 V, so 690 V transformer inputs are not suitable.

Q7: How is current monitoring performed on this board?
A7: Current is monitored via a capacitor and auxiliary rectifier that measures the AC component of the DC output.

Q8: What is required for proper electrical connection of the board?
A8: A flat cable connects the SDCS-FEX-1 to SDCS-CON-2 via terminal X14.
