Key Differences from 5SHY35L4520
5SHY3545L0003: 3500A turn-off, older classic model, mainly used for early ACS5000, PCS6000 high-voltage frequency converters
5SHY35L4520: 4000A turn-off, upgraded expansion model, larger current margin, new converter standard configuration
Both have a voltage of 4500V, installation size, driver pins are common, can be directly interchanged and substituted
Product Features
No Buffer Turn-off Snubberless: No RC recovery circuit required, simplifies the overall topology, low failure rate
Integrated Driver Package: IGCT chip + gate drive, fault feedback integrated, optical isolation drive, strong anti-interference
Priority of dual-side water cooling, optional forced air cooling for high-power conditions, supports multiple series connection for voltage level expansion
Equipped with fault signal terminals, can send overcurrent, overtemperature alarms to the main control unit
