The dV Sentry™ Motor Protection Filter from MTE

The Industry’s First 3-In-1 Protection dV/dt Filter

Industry innovation at its best, the dV Sentry Motor Protection Filter from MTE Corporation helps protect AC motors from the damaging effects of long lead voltages that can destroy Variable Frequency Drives (VFDs), motors and cables. Not only does it offer more efficiency and greater productivity, the dV Sentry Motor Protection Filter also affords unique 3-in-1 protection against peak voltage, high rise times and common mode voltage reduction. This 3-in-1 protection makes the filter suitable for all the demands of industrial equipment providing better protection over a prolonged period of time.

Peak Voltage Protection and High Rise Production

The peak rise protection of the filter stops dangerous voltage peaks in cable leads up to approximately 1,000 feet reducing overheating and bearing damage. Before the creation of the dV Sentry Motor Protection Filter, dV/dt filters only guarded against power distortion established over long lead voltage lengths between VFDs, cables and motors.

A Reduction in Common Mode Voltage

The dV/dt filter is extremely effective as it reduces common mode voltage by over 50%, which lessens the damage to bearings, motor insulation and ground fault trips, and unusual behaviour of VFDs and Programmable Logic Controllers (PLCs). In an industry first, the dV Sentry Motor Protection Filter results in a longer motor life and higher efficiency.

Benefits of the dV/dt Filter

Designed for harsh environment operations, the dV Sentry Motor Protection Filter has the ability to operate in -40 to 60 degree conditions and is suitable for any environment due to its low noise level and small compact design. The dV/dt filter generates a low heat watt loss that will ensure an increased life and greater production for the equipment surrounding the filter and is created to radiate less than other filters on the market. The filter also features a small footprint and easy terminations to make installation faster and easier.

About MTE

MTE Corporation is an international supplier of simple, robust power quality solutions devised to improve the reliability of power electronic systems and adjustable frequency drives. MTE distributes many quality power and filter products for both input (line-side) and output (load-side) of variable frequency drives (VFDs) and power conversion equipment. As a technology leader in its field, MTE has an active product development program with new products like the dV Sentry Motor Protection Filter being added regularly.

By installing a dV Sentry Motor Protection Filter, you are ensuring that premature motor insulation failure, cable damage and a shorter motor life will not occur. The filter will also help reduce unexpected motor problems as the dV Sentry Motor Protection Filter provides the most advanced motor protection in its class.

The dV Sentry Motor Protection Filter is available in NEMA1/2 and NEMA 3R configurations and is backed by a 3-year warranty as well as being UL and cUL Listed. For more information on the advanced dV Sentry Motor Protection Filter by MTE, contact Westek Electronics for details.
