Description

      The OU series power filter is specifically designed for the output of three-phase inverters (VFDs) operating with a PWM carrier frequency between 4kHz and 16kHz. This product effectively suppresses voltage spikes and reduces peak voltage at the VFD output, thereby protecting motor windings and bearings and extending the motor's service life.

      Additionally, it improves overall drive system efficiency, reduces motor overheating, and effectively prevents equipment damage and audible noise caused by high electromagnetic interference (EMI).
