Product Introduction
3ADT306000R001 SDCS-FEX-1 is a diode bridge excitation board that is compatible with ABB's DCS500 and DCS600 series direct current drive systems. Its main function is to provide excitation current for the excitation circuit of the DC motor. Unlike the SDCS-FEX-2A of the same series, this module does not require control by the armature converter. Its independent diode bridge structure can reduce the reliance on interaction with other control units, and it is suitable for excitation circuits with 2-phase or 3-phase power supply, and is compatible with different industrial power supply configurations.

Product Details
The Diode Field Exciter board SDCS-FEX-1 3ADT306000R001 is a single-phase diode rectifier for an AC input voltage up to 500 V and a DC output current of 6 A. The board has to be mounted inside the armature converter module. The excitation current is defined by the DC output voltage (line voltage multiplied by 0.9) and the resistance of the field winding. By using an external resistor in series with the field winding, the field current can be adapted slightly.
If the SDCS-FEX-1 board isn't already installed, it must be mechanically fixed beside the electronic power part SDCS-POW-1 and connected via a flat cable to the SDCS-CON-2 by using terminal X14.

The AC share of the output DC voltage is measured with a capacitor and an auxiliary rectifier and used for current monitoring.
The transistor relay is closed when the DC is flowing (>0.02 A).
