ST2024
ST2024
3.5 KW INVERTER WITH INTEGRATED CONTROL LOGIC FOR SINGLE MOTOR APPLICATIONS
Designed for 400V three-phase motors (star or delta connection), the ST2024 inverter board is engineered for industrial automation systems that demand power, reliability, and precise control. Thanks to its flexible and programmable architecture, it is suitable for a wide range of applications, including:
- Sectional and cold storage doors
- Heavy-duty sliding gates
- Destratifiers
- Automated handling systems
- Agricultural and livestock equipment
The ST2024 is compatible with Startec absolute encoders, Kostal encoders, and other protocols via the integrated RS485 serial interface, enabling advanced position control, movement synchronization, and enhanced safety.
