Though using line and load reactors can protect the VFD systems, and increase the reliability and robustness, users should be aware of some side-effects such as adding cost and weight, requiring …

The installation of load reactors or dV/dT filters at the VFD output can help reduce the quick rise time at the edges of the VFD’s PWM DC square waves. This “rounding off” the square wave increases the …

They work on both the line (input) side and load (output) side to give you an easy solution that reduces nuisance tripping, reduces harmonic distortion and minimizes long lead effects.

Aug 15, 2025 · Load Reactor absorbs many of the power line disturbances which otherwise damage or shut down your inverters, variable speed controllers, or other sensitive equipment. Load Reactors …

Nov 19, 2025 · A Load Reactor, or Output Reactor, is installed between the output terminals of a VFD and the motor. Its main role is to reduce voltage rise time (dv/dt), limit current spikes, and protect the …

The purpose of this document is to provoke some thought on the part of the person(s) responsible for the successful installation of the drive, and to provide some guidelines as to if, where and when a …

What are Reactors? reactor is an inductor wired in series between two points in a power system. React rs are simple electro-magnetic devices, some-times referred to as inductors. They consist of a steel …
