Danfoss 175H4669 DT3 Control Board – VLT AutomationDrive FC 302 Series
When a control board fails inside a Danfoss VLT AutomationDrive, the consequences ripple instantly across the production floor. Variable speed drives lose their command interface, motors run uncontrolled or stop entirely, and entire automated lines grind to a halt — costing manufacturers thousands of dollars per hour in unplanned downtime. The Danfoss 175H4669 DT3 Control Board is the precision-engineered heart of the FC 302 drive, and without it, there is no drive.
The 175H4669 DT3 is a factory-original control board designed specifically for the Danfoss VLT® AutomationDrive FC 302 series — one of the most widely deployed variable frequency drive platforms in global industrial automation. Trusted by OEMs, system integrators, and maintenance engineers across more than 100 countries, the FC 302 platform is the benchmark for high-performance motor control in demanding applications. This control board sits at the core of that platform, managing all logic, communication, and I/O functions that define the drive’s intelligence.
