Our SW Series output filters are designed to extend the life of motors, bearings, and cable by reducing voltage spikes with superior peak voltage protection for long lead motor applications.
Phase Technologies is proud to offer the SW Series Sine Wave Filter, designed to provide smooth, sinusoidal voltage waveforms in demanding motor applications. Engineered to work between the variable frequency drive (VFD) and the motor, the SW Series significantly reduces motor heating, audible noise, and electrical stress by eliminating high-frequency voltage components.
The SW Series utilizes high-grade distributed gap alloy powder cores to ensure low core losses, excellent thermal stability, and compact form factors. This advanced construction delivers reliable performance, peak voltage reduction, and long service life.
Whether used as a standalone NEMA 3R solution or integrated into a custom-built 508A VFD panel, the SW Series provides a robust, space-efficient option where motor protection and system efficiency are a top priority.
