Yaskawa Electric YPHT31288-3A Capacitor Circuit Board

The Yaskawa Electric YPHT31288-3A capacitor circuit board is a drive-capacitor and power-conditioning PCB used inside industrial AC drives to manage DC bus charging, stabilize inverter operation, and regulate power delivery. Designed for internal mounting within Yaskawa VARISPEED and CIMR-series inverters, this industrial-grade board provides DC bus filtering and capacitor charge/discharge control to support motor control in CNC machines, conveyors, pumps, fans, and motor control panels. Key identifiers include model YPHT31288-3A and alternate ID ETX003790; it is a legacy/discontinued component available as used, surplus, or refurbished inventory. Compatible with Yaskawa CIMR/P7/F7 inverter platforms, the board supports inverter capacitor management and power stabilization within drive systems. Manufactured in Japan, this internal drive-mounted PCB contributes to inverter capacitor charging, filtering, and power regulation. Common replacements include YPHT31288-2A, YPCT31418-2C, and YPCT31392-1A.
