ABB DSMB-01C ACS800 Multi-Drive Rectifier Unit Power Supply and Monitoring Board

Product Description

DSMB-01C is the power and monitoring board for ABB ACS800 multi-drive rectifier unit, a core component of ACS800 high-power drive system. This board supplies stable auxiliary power for the control circuit inside the rectifier unit, and monitors voltage, current and temperature signals of rectifier modules in real time. It implements fault detection and alarm output, with overvoltage, overcurrent and overheat protection functions. Adopted industrial-grade PCB design with strong EMC anti-interference performance. It is widely used for assembly of multi-drive cabinets and on-site spare parts replacement, serving as critical spare part for ACS800 rectifier unit.
