dV Sentry Filter

This Filter is a next-generation motor protection solution designed to safeguard motors and variable frequency drive (VFD) systems from harmful voltage stress. Built on patented technology, it is the first filter to combine common-mode noise reduction, peak voltage protection, and rise-time control into a single, integrated unit—delivering superior protection for motors and insulation systems.

With a compact footprint and easy-to-terminate design, this device simplifies installation while reducing cabinet space requirements. It also operates quietly and generates less heat than traditional dv/dt filters, improving both system efficiency and long-term reliability. For applications requiring maximum motor protection and performance, it stands apart as the most advanced solution available.
