3LH Enterprise Chassis

Light Commercial and Agriculture AFE VFD

The 3LH Series Enterprise VFD has nearly all the features and performance of the larger 3LH systems integrated into a compact and field-serviceable enclosure.

3LHE Series drives have a unique active switching input module that does not produce high levels of harmonic distortion. These drives are IEEE-519 compliant with no additional harmonic filter required. The active front end also provides the added benefit of power conditioning for the VFD. This allows the user to set the output without concern for utility power fluctuations.

See the 3LH Signature or Performance for applications requiring more than 50 horsepower.
