MTE Introduces dV E-Series – The Ideal dV/dt Solution for Essential Motor Protection

The new dV E-Series filter eliminates reflective wave, provides peak voltage protection, and rise time reduction for any application out to 1,000 ft of cable.

Menomonee Falls, WI | December 14th, 2021 – MTE Corporation, a world leader in the design and manufacture of high-efficiency electrical power quality solutions for commercial and industrial applications, announces the introduction of its new best-in-class dV E-Series motor protection filter. Using a dV/dt filter enables uptime and protects AC motors from the destructive effects of the variable frequency drive (VFD) pulse width modulated voltage that can damage cables and motors.

The dV E-Series mitigates reflective waves, reduces rise time, and limits peak voltage resulting in a reduced motor heating, longer cable and motor life, and a significant reduction in downtime and total ownership cost.  The dV E-series offers up to 60% lower watts loss versus competitive dV/dt filters, enabling more efficiency and savings, and ensuring longer life and protection for equipment around the filter. It is mounting compatible with MTE’s dV Sentry and competitive options and features a compact design that is up to 73% lighter and 35% smaller for easier installation in crowded cabinets.  The robust design operates over an extended temperature range from -40°C to 60°C and is backed by a 3-year warranty.

“In collaboration with our customers, we identified a need for a high-value motor protection filter to bolster our industry leading solutions,” said Ahsan Javed, VP of Marketing at MTE Corporation. “Our comprehensive motor protection portfolio now includes the new dV E-Series, dV Sentry, SineWave Guardian, and SineWave Nexus, which provides our customers with the best products for any application.”

The dV E-Series is part of MTE’s industry leading Power Quality Express stocking initiative. With over 600 SKUs in stock or ready to ship in under 10 days, MTE has the right product, when you need it.
