MTE dV Sentry dV/dT Filters


MTE’s latest technological innovation has made the dV Sentry the revolutionary solution for motor protection. With its patented design, the dV Sentry is the first proven filter that provides common mode reduction, peak voltage protection and rise time reduction – all in one unit. This gives greater motor protection over time.

It features a small footprint and easy terminations to make installation faster and easier. It also runs quietly and radiates less heat than previous filters. The unique design of the dV Sentry allows for greater load side protection from voltage spikes and common mode voltage for your AC motors, cable and VFDs.
