September 15, 2014 - MTE announces dV Sentry motor protection filter. The dV/dt filter helps protect AC motors from the destructive effects of long lead voltages that can damage variable frequency drives (VFDs), cables, and motors. The 380V to 600V dV Sentry offerscomprehensive three-in-one protection for VFDs and motors against peak voltage, high rise times, and common mode voltage reduction. The dV Sentry is suited for the demands of industrial equipment including HVAC, water/wastewater and irrigation. The dV Sentry reduces common mode voltage by over 50 percent, which significantly reduces damage to motor bearings, motor insulation and unexpected ground fault trips and erratic behavior of VFDs and Programmable Logic Controllers (PLCs). Designed for operations in harsh environments, the dV Sentry operates from -40°C to 60°C. The dV Sentry features a small compact design as well as lighter weight, facilitating easier installation. Operating at a low noise level (<65 db), the dV Sentry can work in virtually any environment. Moreover, the dV Sentry offers a low watts loss (heat) that helps ensure longer life and protection for equipment around the filter. Available in NEMA1/2 and NEMA 3R configurations, the dV Sentry is backed by a 3-year warranty and is UL and cUL Listed.
