Star-delta start is the main feature distinguishing STARDELTA PRO, our new electromechanical control panel adding the reduction of start currents and mechanical stress to completeness and versatility. With the same simple and immediate user interface distinguishing the entire Elentek range, Stardelta Pro has 6 preset operating modes, additional connectivity options, control and expandability.
- Maximum control - Integrate the most complete system protections
- Flexibility - Multiple inputs available for several applications
- Reliable in any condition - Accurate motor current reading (even in ambient conditions)
