AC7 Matrix Drive

Specifications & Ratings

Features

  1. Low harmonic distortion
    1. 7% max input current distortion which is 90% less then a traditional drive
    2. No harmonic mitigation devices required
  2. Line Regeneration
    1. AC7 is fully regenerative improving system efficiency and eliminating all external components (converter modules and resistors)
    2. Reduction in system energy consumption by 40-60% in overhauling applications
  3. Motor and System Friendly
    1. Solves typical motor drive issues (very long cable lengths, bearing currents, and common mode currents)
    2. Elimination of the DC Bus extends product life and reduces physical size
