Product Overview
The Venema VCP-SD Series control panels are designed for automatic star-delta starting of three-phase motors ranging from 5.5 kW to 315 kW. They provide smooth acceleration and significantly reduce inrush current during motor start-up, protecting both the motor and the power network.
Each panel is assembled using industrial-grade components and configured for safe, stable, and long-term operation in irrigation, pumping, and industrial process systems. The modular design and spacious internal layout ensure easy maintenance and customization for different applications.
