In the field of industrial automation, variable frequency drives (VFDs), as core equipment for motor control, directly impact the efficiency and stability of production lines. Leveraging its profound technical expertise, V&T has launched the VTS31 series general-purpose VFD—a compact drive offering exceptional compatibility and a rich set of features, delivering an innovative solution for variable-torque load applications such as fans and pumps.

The VTS31 series is a compact general-purpose variable frequency drive developed by V&T. It supports both synchronous and asynchronous motor control and comes standard with an LCD keypad. Featuring simple operation, small size, light weight, and comprehensive protection functions, it is ideally suited for variable-torque load applications like fans and pumps. The series covers motor power ratings from 1.5 kW to 500 kW.

Key Features:

• Compact design
• Supports V/F control, asynchronous current-vector control, asynchronous voltage-vector control, and open-loop synchronous motor control
• Optimized for fan and pump applications
• Standard communication protocols: Modbus RTU and CANopen
• Multiple keypad options: standard Chinese/English LCD keypad; optional LED keypad
• For models rated up to 650 A: multiple drives can share a common DC bus
• Cabinet-type units (725 A and above) can be customized to meet specific customer requirements and on-site installation needs regarding input/output wiring configurations
