Product description

AC Drive Control Techniques Commander SK Series

The Control Techniques Commander SK AC Drive has been designed as a simple, compact, cost effective AC Drive frequency inverter controller that delivers performance with simplicity and ease of use. With all the parameters you need for 90% of applications printed on the front of the drive, Commander SK AC Drive ensures installation and commissioning are straight forward.

  • Power: 4kW
  • Amps: 9
  • Supply: Three Phase 400v
  • Model: SKC3400400 4kW
  • Filter: Built-In
  • Performance: Mid Range
  • Dimensions: 0 0 0
  • Weight: 7 kg
  • Torque: Constant Torque General Purpose

Type: Control Techniques SKC3400400 4kW is a simple compact senseless vector AC Drive frequency inverter

However, for more demanding applications, Commander SK AC Drive frequency inverter can deliver the benchmark functionality of its larger Solutions Platform products and at no extra cost on the base drive itself. Plug-in options, dynamic performance, PLC functionality and other benchmark features ensure that in more complex applications the Control Techniques Commander SK can deliver more than the average general purpose drive – giving you lower cost solutions and better productivity in your motor control applications.
