Strict full-process factory tests including high-voltage withstand, accelerated aging and short-circuit durability inspection are implemented for every finished component to comply with CE and UL international industrial safety specifications before shipment.

Detailed Electrical, Mechanical & Thermal Specifications

In core electrical parameters, its repetitive peak blocking voltage (VDRM) hits 6500V; rated continuous average on-state current reaches 1900A at 85℃ baseplate temperature under 180° conduction cycle, while maximum allowable instantaneous surge current peaks at 6000A to withstand equipment startup inrush and abrupt load current surges. The typical turn-off time is controlled within 1.2μs to support stable medium-frequency switching and reduce overall converter switching loss, lifting the comprehensive energy efficiency of matched medium voltage drives above 98%. It exclusively pairs with ABB original GDU 3BHL000390P0104 gate drive unit via fiber-optic signal transmission complying with IEC 60747-9 standard; fiber isolation completely separates high-power main circuit and low-voltage control circuit to restrain EMI interference, meanwhile feeding real-time overvoltage, overcurrent and overtemperature fault signals back to drive control system for instant protective locking. The matched gate drive requires ±15VDC auxiliary power supply from internal converter power source for stable triggering performance.
For mechanical and thermal indexes, the component adopts sealed flat ceramic packaging integrated with high-conductivity copper baseplate; overall dimension measures 190mm×140mm×40mm with net weight around 2.6kg, designed with bolt fastening structure to directly install on water-cooled heat sinks for efficient heat dissipation. Rated operating junction temperature ranges from -40℃ to +125℃, and storage temperature spans -55℃~+150℃, enabling steady long-term running under high-temperature, humid and dusty harsh on-site industrial environments of chemical workshops and open-air power plants. Built-in multi-layer hardware protection circuit automatically cuts off switching output upon short-circuit, overheat or abnormal DC bus voltage fluctuation to avoid permanent breakdown of drive power units.
