Micro Series  – Leeson’s Micro Series line of compact inverters offer “Big drive” features for adapting standard or premium efficient three-phase motors to adjustable speed operation.  They utilize the latest technology in software and power conversion circuitry.  They are easy to program and read-out in plain English, eliminating the frustration and time involved in trying to translate symbols.  Complete rugged steel enclosures offer protection that is not always provided with plastic enclosures.  Built-in thermal overload protection reduces additional costs.  Heavy duty wiring terminals and accessible conduit openings reduce installation time.

Features Include:

  • 0-120 Hz – Output Frequency
  • 16 bit Intel microprocessor
  • Four-Preset speeds
  • Adjustable acceleration and deceleration times
  • Adjustable carrier frequency
  • Analog output signal – 0-10VDC, speed or load
  • Two auxiliary contacts: One form C relay and two open collector outputs
  • Forward/Reverse
  • Password Protected
  • Dynamic Braking kits available
  • Remote Keypads available
  • Slip compensation
  • Constant torque with adjustable current limit
  • UL listed
