Product Description
It generates six-channel firing pulses, stabilises the DC bus voltage and performs closed-loop voltage regulation to suppress grid fluctuation and sudden load changes. Designed for metallurgy, printing, winding and heavy process automation, it is a critical power-control spare part supplied as an original ABB board. The ABB DSAB-01C is a dedicated SCR (thyristor) rectifier trigger control board engineered for ABB ACS800 multi-drive rectifier units.
Basic Product Information
- Integrated overvoltage, overcurrent, undervoltage, overheat, phase-loss and thyristor-fault protection with fault interlock and alarm output.
- Anti-EMI industrial circuit design for stable operation inside drive cabinets.
- Modular plug-in structure enables rapid maintenance replacement and complies with IEC industrial electronic safety standards.
- Generates precise six-channel SCR or thyristor firing pulses for accurate rectification and DC-bus regulation.
