Soft starter and motor controller
iSFT
Cognito Quam Electrotechnologies Ltd
The iSFT intelligent motor starting controller addresses demanding motor starting applications by controlling all aspects of motor load starting, running, stopping and error handling.
Typical applications for the iSFT are:
* Control of high inertia loads such as large fans and crushers,
* Control of high static friction loads such as material transport mechanisms, and
* High availability, fully protected loads such as in waterwork pumping stations.
Main features are:
* Complete and versatile control interface to a three leg, six thyristor reduced voltage soft starter power assembly and its protection circuits,
* Four universal connection 24 VDC, galvanically isolated user-configurable control inputs,
* Eight galvanically isolated user-configurable transistor bit outputs,
* Four user-configurable 5A contact relay outputs,
* Fully programmable parameters and function for each input and output,
* Fully programmable galvanically isolated analog voltage and current output,
* External Pt100 temperature interface,
* Fully programmable and versatile two tier fault and warning parameters,
* True RMS measurement of each phase voltage and current,
* Real time thermal current calculation,
* Line frequency, phase sequence and integrity monitor,
* Complete integration within a Quamatic or Modbus network and other supervisory systems,
* Standard dimensions IP54 polyester membrane front panel with five large digit LED and four switch, and
* Simple, self-contained, unattended operation by non-specialist personnel.
