Self-learning soft starter motor series
Carlo Gavazzi’s RSGD series of self-learning soft starters are designed for motor applications up to 100Hp. The RSGD is a compact 75mm wide and easy-to-use 3-phase soft starter for ac induction motors up to 100A. The RSGD is designed for 3-phase fixed speed ac induction motor applications where there is the need to reduce starting current to minimize the stresses on a motor during start and stop. Applications include control of pumps, fans, and compressors for water treatment, agriculture, building automation, and HVAC industries. The self-learning algorithm has been adapted to work with different applications without needing to adjust the initial torque.
The integrated electronic overload protection, the PTC input, and a number of built-in diagnostic functions provide more protection to the motor. The RSGD is also equipped with Modbus two-wire serial communication protocol which can be interfaced to different programmable logic controllers (PLCs) for enhanced control diagnostics of the system status. Energy, voltage, current and other electrical variables can be easily communicated to a PLC for real-time monitoring of the motor condition.
