dV E-Series Motor Protection Filter


Eliminating reflective waves, providing peak voltage protection, and enabling uptime for applications out to 1,000 ft (304.8 m) of cable, the dV E-Series filter protects AC motors from the effects of the variable frequency drive pulse width modulated voltage that can damage cables and motors.


By reducing rise time and limiting peak voltage, the results include reduced motor heating, longer cable and motor life, and a reduction in downtime and total ownership cost.


The dV E-series offers up to 60% lower watts loss, enabling more efficiency and ensuring protection for equipment around the filter. The robust design operates over an extended temperature range from -40 to 140°F (-40 to 60°C).
