PLC, frequency converters, and servers

In the core components of industrial control systems—PLCs, inverters, and servo drives—isolation chips serve as a critical safeguard against electrical risks. They deliver 3.75 kVrms high-voltage isolation to prevent cross-current in inverter IGBT drivers and ensure zero-distortion, millisecond-level response times for servo encoders. Compliant with the IEC 61000-4 standard, these chips enhance noise immunity by 50%, reduce failure rates by 30%, and extend equipment lifespan by 20%, forming the foundation of reliable industrial automation.
