FUJI EP-3603D-C Inverter Power Drive Board – FRENIC Series Variable Frequency Drive Component
When a power drive board fails inside a FUJI FRENIC series variable frequency drive, the consequences are immediate and costly: production lines halt, motors lose control, and unplanned downtime cascades across the facility. The EP-3603D-C is the precision-engineered power drive board that keeps FRENIC series inverters running at peak performance — and without it, there is no substitute that maintains OEM-level reliability.
The FUJI EP-3603D-C occupies a critical position within the FRENIC inverter family, serving as the core power switching and gate-drive interface between the control board and the IGBT power module. As FUJI Electric’s FRENIC series has become one of the most widely deployed VFD platforms in Asia-Pacific and global industrial markets, the EP-3603D-C has established itself as an essential spare part for maintenance engineers and OEM integrators worldwide.
