Collection: Input Chokes

Invertek input chokes are used on the supply side of compatible Optidrive variable frequency drives to help reduce harmonic currents, voltage distortion, and mains-borne interference. They can also provide additional protection against transient voltage spikes from the incoming power supply.

Input chokes are often recommended where power quality is poor or unknown, where large switching loads are present, or where the supply environment is electrically demanding. Contact us if you need help matching an input choke to a specific Optidrive model.
