Commander SK - General Purpose AC Drive

Compact, easy to use AC drive for a wide range of applications

Commander SK

0.25 kW - 132 kW (0.33 hp - 200 hp)

100V / 200V / 400V / 575V / 690V

Commander SK is easy to use and offers great value. The drive modules are compact and offer excellent motor control.

With onboard intelligence, I/O, Ethernet and fieldbus communications options, Commander SK allows you to do far more than you would expect from a standard open loop drive.

  • Features

    A simple drive to solve the widest range of applications

    Commander SK simplifies the installation and configuration of the drive, saving time, yet has the performance and depth of functions required to solve more complex applications than other drives in its class. Key features include:

    Easy to maintain

    Optional Smartstick allows drive settings to be stored, backed-up and easily re-loaded

    Expandable 

    Option modules for Fieldbus and Ethernet connectivity, real-time-clock and additional I/O

    Flexible

    Minimize inventory through single or three phase operation with 200V drives and dual fan/pump and machinery duty ratings on higher power modules

    Feature packed

    On-board serial port with Modbus RTU for connecting to other automation equipment or PC tools for access to advanced features

    Intelligent 

    Programmable logic control with the optional Logicstick memory
