VFD DC-Bus Support
Direct ride-through support for VFD-driven equipment.
Best fit: Best when the production trip is concentrated in accessible VFDs.
Explore VFD DC-Bus Support →Protection Solutions
Choose the Right Protection Boundary
Protect the equipment that actually causes production to stop — at the VFD DC bus, across a critical AC feeder, or after further diagnosis when the failure point is not yet clear.
Two Main Protection Paths
WS-DVR Dynamic Voltage Restorer
Whole-line AC protection for mixed sensitive loads.
Best fit: Best when multiple loads on one critical feeder must ride through the disturbance together.

You do not need to know whether the problem is the VFD, the control system, or the feeder before contacting Wilson.
Tell us what stopped, what fault appeared, and what you observed during the disturbance.
Describe the EventNo waveform or power-quality record is required.
