Привод Frequency AC Drive Commander SK, SKBD200110 /220240V /5,2A /1,1KW

Important! In 2014, the serial production of a new generation of converters began Unidrive M400, which will completely replace the Commander SK frequency converters by 2016. In accordance with the policy of promoting new products by Control Techniques, a special price for electric drives is set for 2015 Unidrive M400 On average, it is 10-15% lower than the price of Commander SK electric drives.

Commader SK frequency converters are a universal AC Control Techniques electric drive designed to solve general industrial tasks of electric drive control. The optimal ratio of reliability, functionality and cost of the electric drive, ease of setup and commissioning, modular principle of functional expansion, built-in PLC are the distinctive features of the Commander SK converters. The use of electric drives of this series allows equipment manufacturers and service providers to minimize the cost of the system being created.

Technical characteristics of the Commander SK electric drive

• Rated power: 0.25-132 kW; 
• Supply voltage ratings: 110/220/380/575/690 V; 
• Output operating frequency: 0 -1500 Hz; 
• Switching frequencies: 3kHz – 18KHz (low noise level);

Modes of operation of frequency converters Commander SK

• U/f – control /scalar control of an asynchronous electric motor; 
• Vector control in an open loop by an asynchronous electric motor. 

In scalar control mode, both single–axis and multi-axis control is possible - the electric drive can control several electric motors simultaneously.
The vector control function makes it possible to ensure the constancy of the operating torque of the electric motor and significantly expands the application areas of the converters.

Areas of application of Commander SK inverters

scalar control mode: conveyor systems, pumps, fans, compressors, presses;
vector control mode: cutters, extruders, receivers, recoilers, winding equipment, weaving and spinning machines, mixing plants, crushers, metalworking machines, cranes, elevator and lifting equipment.
