AC Drives

LTI™ AC drives, offered in air-cooled and liquid-cooled versions, are designed for efficiency, productivity, and reliability. These rugged AC drives, beginning at 400 hp, feature a slimmer design (just 14 inches x 36 inches, about one-third the size of conventional AC drives), and command significantly less floor space. 

These compact drives are also lighter than similar AC drives. In addition to their compact size and lighter weight, LTI AC drives deliver greater power density than competitive systems.  These drives also feature a proven low maintenance design, superb fuel efficiency, and torque performance that meets the requirements of the most demanding application.

Features of LTI™ AC Drives

  • Exacting algorithmic torque regulation
  • Energy-efficient regenerative or dynamic braking
  • Factory load testing for quality assurance
  • Fully regenerative active front end for energy efficiency and reduced component wear
  • Easy installation using standard cabling
  • No auxiliary brake required for drawworks (drilling application)
