ARC IGBT 3-Diode PCB Board for Inverter Welding Machine (Secondary Fast-Recovery Rectifier Card)

SKU: AFDCB8B2-D852-4EF3-B6D9-B75FCDE66565

Heavy-duty ARC IGBT 3-Diode Secondary Rectifier PCB Board engineered for single-phase ARC 200 and ARC 250 inverter welding power sources. Designed specifically to mount fast-recovery rectifier diodes (such as D92-02, ESAD92-02, or 150EBU series), it handles secondary high-frequency AC-to-DC rectification with minimum thermal loss. Key Features & Specifications: - 3-Diode Symmetrical Layout: Optimized for full-wave secondary rectification, ensuring balanced thermal dissipation across heat sinks. - Heavy-Copper PCB Traces: Thick, wide copper bus pathways reinforced with high-density solder flow to sustain continuous 200A-250A welding currents. - Integrated Snubber Network: On-board footprints and mounting traces for snubber capacitors and resistors to suppress reverse-voltage switching spikes. - Direct Chassis Compatibility: Standard mounting dimensions compatible with major IGBT-based modular inverter welding machine chassis. - High Thermal Resistance: Double-sided FR-4 epoxy laminate resistant to workshop heat, vibrations, and continuous industrial duty cycles. Typical Repair Applications: - Replacement for burnt or shorted secondary output rectifier boards. - Repairing ARC 200/250 machines showing "OC" (Over-Current) or zero DC arc output voltage. - Custom inverter welding machine manufacturing and refurbishing.
