Overview

The Hammond Power HPS dV/dT filter, SKU CD1X0035F, is an open-style unit designed for industrial applications. This filter is specifically engineered for installation between variable frequency drives (VFDs) and electric motors, particularly when longer cable lengths are utilized. Its primary function is to mitigate the damaging effects of voltage spikes and rapid voltage rise (dV/dt) that can occur over extended motor leads. By attenuating these transient voltages, the dV/dT filter helps to extend the lifespan of motor insulation and reduce the risk of premature motor failure. This unit is rated for up to 35 amperes and operates at a maximum voltage of 600 volts. The open-style construction allows for efficient heat dissipation and straightforward integration into existing control panels or motor control centers. Manufactured by Hammond Power, a recognized name in power quality solutions, this dV/dT filter is a critical component for ensuring reliable motor operation in VFD-driven systems. Its application is crucial in environments where motor insulation integrity is paramount and extended cable runs are a necessity, such as in process industries, manufacturing plants, and HVAC systems. The UNSPSC code for this product is 83101808, and it is manufactured in France.
  • 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.
  • Open style construction for easy integration
  • Reduces motor insulation stress and extends motor life

How to Install the dV/dT Filter

This guide provides step-by-step instructions for the safe installation and initial setup of the dV/dT filter, ensuring proper connections and configurations.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors

  1. Inspect the dV/dT Filter

    Immediately after receiving the dV/dT filter, inspect it for any transit damage and ensure it matches the shipping documents. If any damage is found, do not energize the unit and contact the manufacturer.
