Description
The ABB DSSB-01C (part number 3AFE68300746 / 68300746) is a main control board for DSU (Diode Supply Unit) systems, manufactured by ABB. It serves as the core processing and coordination module for ABB ACS800 series medium-voltage AC drive systems, managing the rectifier stage and ensuring stable DC link operation.
This control board functions as the "brain" of the inverter/rectifier system, executing all control algorithms, communication management, and fault diagnostic functions. It is responsible for controlling the drive's rectifier stage, converting AC input power to DC power for the subsequent inverter stage that drives the motor. The board utilizes a 32-bit microcontroller with PWM (Pulse Width Modulation) control to precisely regulate power conversion, fault detection, and external system communication.

The ABB DSSB-01C (Product ID 68300746) is a main control board kit designed for Diode Supply Units (DSU) in ABB ACS800-07 cabinet-built AC drives. Acting as the interface between power electronics and control logic, it ensures stable, high-precision performance, typically in industrial, heavy-duty applications. The board should be treated as a sensitive electronic component; often provided as a PC board kit.Limits exist on DC capacitor charging; avoid exceeding five power-ups in ten minutes.
- Pulp & Paper: For rollers, winders, and process control.
- Metals & Mining: For drilling rigs, rolling mills, and heavy conveyors.
- Oil, Gas & Chemical: For specialized pump and compressor management.
- Power & Water: For water treatment facilities and power generation peripherals.

Signal Integrity: Use shielded control cables to prevent interference. Ensure the shield is properly terminated at the grounding shelf.
Phase Order: When reconnecting motor cables, verify that the phase order is correct to prevent reverse rotation.
Digital I/O: The board handles signals in the 0–24 VDC range. Ensure input/output levels match these specifications to avoid damaging the 16 available channels.
Technical notes
The board features robust protection mechanisms including 4000 V electrical interface lightning protection, 1.5 A overcurrent protection, 600 W surge protection, and DC 1500 V voltage isolation. Dual power supply redundancy is supported with DC 9-36 V input range and reverse polarity protection. These features ensure reliable operation in demanding industrial environments.
