dV E-Series FAQs
How do I size the filter?
The filter should match the drive/motor voltage and current ratings. If an exact current rating is not available, go to the next largest rating.
Does the Carrier Frequency Matter?
Yes. Heat loss increases with an increased carrier frequency. Lower carrier frequencies reduce motor voltage stress, and drive temperature.
Do I mount the filter near the drive or the motor?
The filter should be mounted as close to the output of the VFD as possible. This method helps to protect the motor as well as the motor leads.
What is the warranty for the dV E-Series Filter?
MTE warrants the dV E-Series for a period of three years from the date of shipment.
What does Kit (Part Number DVTKxxxxE) mean?
Kit units ship with the reactor and resistor as separate components. It is the customer’s responsibility to interconnect the reactor and resistor.
What does Panel (Part number DVTPxxxxE) mean?
Panel unit ship complete with all filter components necessary except customer supplied wire.
What types of enclosures can I get with the filter?
The dV E-Series is available in two types of enclosures. NEMA 1/2 (Part number DVTGxxxxE) and NEMA 3R White (Part number DVTWxxxxE).
What operating voltages is the filter designed for?
The filter is designed to operate between 208V to 600V, 0-60Hz. Derating applies above 60Hz (see chart).
Is there an over temperature switch?
The dV E-Series is new. Is it UL listed?
The dV E-Series is UL/cUL Listed and CE marked.
What is the heat loss from the filter?
The overall filter efficiency is greater than 99%. Heat loss will vary with carrier frequency, motor lead length, and cable type.
What is the continuous current and overload rating?
The filter is rated for 100% continuous current, 150% current for up to 1 minute, and 200% current for 10 seconds.
