Can be matched with the Symphony INFI90 DCS (TRM01, BIO01, PSM02 Rack) for valve system monitoring and acquisition

Maintenance and Replacement Key Points
Replacement of spare parts must be a complete set of 3BHL000986P3002 valve section, cannot disassemble and assemble the 5SDF1045H0002 chip separately, disassembling and assembling is likely to damage the press-fit stress and cause cracking
After replacement, it is necessary to conduct water cooling circuit leak detection, optical communication calibration, equalizing characteristic test
Monitoring Points: IGCT Chip Temperature, Water Cooling Inlet and Outlet Temperature Difference, Optical Trigger Status, Absorption Circuit Voltage
Spare parts are high-power high-voltage valuable spare parts, mostly imported original factory inventory, replacement cycle for discontinued models is longer

Classification of the Same Series
5SDF0845H0002: Same as 4500V, Switching Current 845A, Smaller Power
5SDF1245H0002: 4500V/1245A High Current Version, Different Material Code Suffix
3BHL Series is the entire valve component material, the digital suffix represents current, heat dissipation, and drive version differences, cannot be directly interchanged
