Overview
- The dV/dT filter combines an inductor and parallel resistor network to mitigate both high frequency components and voltage spikes between the VFD and motor.
- The filter can mitigate the effects of reflected wave voltages greater than what a reactor alone can accomplish.
- The filter provides protection to the motor by slowing down the rate of voltage increase and minimizes the damaging peak voltages that occur within the motor’s windings and along the length of cables feeding the motor.
- Type 1 enclosure for environmental protection
- Reduces motor insulation stress and voltage spikes

How to Install the dV/dT Filter
This guide provides step-by-step instructions for the installation and initial setup of the dV/dT filter, ensuring proper wiring and configuration for safe operation.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors
- Inspect the unit
Immediately after receiving the dV/dT filter, inspect it for any transit damage and verify it against the shipping documents. If any damage is noted, do not energize the unit and contact the manufacturer.
- Mount the filter
Secure the dV/dT filter to a suitable mounting surface using the provided mounting screws. Ensure that the unit is level and properly supported.
- Connect the wiring
Connect the output phases U, V, and W from the variable frequency drive to terminals A1, B1, and C1 on the dV/dT filter. Connect terminals A2, B2, and C2 to T1, T2, and T3 of the motor. Ensure all connections are tight and secure.
