The HPS dV/dT filters are specifically designed for use between variable frequency drives (VFD’s) and motors when longer cable lengths are used.
The HPS Centurion™ D1 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 D1 can mitigate the effects of reflected wave voltages greater than what a reactor alone can accomplish. The D1 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.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
