VFD Control Panel (Variable-Frequency Drive Cabinet)
Industrial Automation Control Panels
- Protection Functions
Equipped with comprehensive protection features, including input overvoltage and undervoltage protection, momentary power loss protection, phase-loss protection, output short-circuit protection, overload protection, system overheat protection, and protection against permanent magnet motor stall, lock rotor, overvoltage, and undervoltage. These safeguards ensure stable and safe operation of the motor and connected systems.
- Compact Structure
The VFD control cabinet is designed with a compact, integrated structure that provides dustproof and splash-proof protection, suitable for various on-site environments. Depending on process requirements, it can be equipped with a braking chopper and braking resistor, enabling deceleration stop and zero-speed braking for precise motor control and improved operational safety.
