Description

Control Techniques Commander SK Series AC Inverter for 2.2kW (3HP) 230V 3 Ph motor in VxF or Sensorless Vector control to 9.6A. Converts fixed frequency single or three phase 230V input to variable frequency three phase 230V for a standard AC Induction motor.

The SKCD200220 has a wealth of plug-in option modules designed to expand the functionality of the Commander SK AC drive. These include keypads, storage, communications modules, input/output modules and automation options. Keypads and Storage. SK-Keypad - This is a panel mounting LED display and keypad with a high IP65 rating

Control Techniques' 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.

The Commander SK has been designed to be a simple, compact, cost effective AC motor speed 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 ensures installation and commissioning are straight forward. However, for more demanding applications, Commander SK can deliver benchmark functionality at no added cost to the base drive itself.

Unidrive M: compatibility with Commander SK and Unidrive SP
Mechanical
• Compatible physical dimensions, weights and surface mount footprint.
• When retrofitting surface mount drives, existing mounting holes can be reused-negating the need for additional drilling. Mounting holes are in the same place or retrofit kits are available.
Electrical
• Power and control wiring adopt the same philosophy as Commander SK and Unidrive SP.
