Control Techniques CTStart
Overview
CT-START is a multi-function electronic motor starter
incorporating a microprocessor, control circuitry and a
thyristor power stage. It is designed for use with all 3-phase squirrel cage induction
motors.
Unlike the traditional systems (Direct-on-Line (D.O.L.),
star-delta, resistors, etc), CT-Start limits and controls
the starting current and ensures very smooth and steady
acceleration.
CT-START includes protection and control
system functions which means that installations are kept simple and component costs are reduce
FEATURE PERFORMANCE
Current Limitation
All traditional motor starter systems cause a current peak
during the starting phase, which can vary between 6 and 9
times the motor nominal rated current.
CT-START, by simple adjustments, can limit the current precisely during the start-up
phase, whilst monitoring all the thermal characteristics of the motor.
