16CARLO GAVAZZI Automation Components. Speci cations are subject to change without notice. Illustrations are for example only.16Carlo Gavazzi offers a comprehensive range of soft starting and motor reversing solutions for single and three phase squirrel cage a.c. induction motors. Carlo Gavazzi offers solutions for scroll compressors (RSBS, RSBD, RSBT, HDMS), centrifugal pumps and ventilators (RSWT). For other applications such as dryers, mixers, fans, hydraulic pumps and piston compressors, general purpose solutions such as the RSGD are available. Carlo Gavazzi soft starters are designed with self-learning algorithms for ease of use and better load matching. The RGTS and RSHR are fully solid-state solutions for single and three phase applications that require high frequency switching. In addition, customized solutions to satisfy specific customer requests can be provided.Soft starters• Operational current: 55 to 100 A• Operational voltage: 220 - 600 VAC• Self-learning algorithm for current reduction and current balancing• PTC input and remote reset of alarms• Integrated motor overload protection (Class 10)• 3 relay outputs: top of ramp, alarm, run• Approvals: CE - cULus - CCC - EACGeneral purpose soft starters RSGD 75 mm• Operational current: up to 11 A• Motor reversing relay• Built-in interlock function• Integrated voltage transient protection• Approvals: CE - UL - cULMotor reversing relay RR2A• Operational current: 12 to 45 A• Self-learning algorithm with current balancing• Top of ramp and alarm relay indication• Max. starts per hour: 12• Approvals: CE - cULus - CCC - EACScroll compressor soft starters RSBD 45 mm• Operational current: 12 to 37 A• Eliminates the need for a start capacitor typically used to start single phase motors• >70% start current reduction on scroll compressors and submersible pumps• Tool-free terminals• Approvals: CE - cULus1-phase dynamic motor starter HDMS• Operational current: 16 to 32 A• Self-learning algorithm with high pressure function• No user adjustments required• Optional: serial communication (Modbus) [Version: VC1HP]• Max. starts per hour: 12• Approvals: CE - cULus - VDE - CCCScroll compressor soft starters RSBT 45 mm• Operational current: 55 to 95 A• Self-learning algorithm for current reduction• No user adjustments required• Max starts per hour: 12• Approvals: CE - cULus - CCC - EACScroll compressor soft starters RSBD 75 mm• Operational current: 55 to 95 A• Self-learning algorithm for improved current reduction• Optional: serial communication (Modbus) [Version: VC]• Max. starts per hour: 12• Approvals: CE - cULus - CCCScroll compressor soft starters RSBT 120 mm• Operational current: 12 to 25 A• Algorithm reduces oscillation during pump start and stop• Manual or auto-reset of alarms • Integrated overload protection• Approvals: CE - cULus - CCC - EACPump and ventilator soft starters RSWT 45 mm• Operational current: 32 A• Current limit starting with high pressure function• Max. starts per hour: 10• Approvals: CE - cULus (pending)1-phase compressor soft starter RSBS• Operational current: 12/16/25 A• Operational voltage: 100 - 240 VAC• 100 kA short circuit current rating• Max. starts per hour: 10• Approvals: CE - cULus1-phase solid state soft starter RGTS• Operational current: 32 to 90 A• Operational voltage: 220 - 600 VAC• Up to 20 starts per hour• Integrated overload protection and remote reset for alarms• Approvals: CE - cULus - CCC - EACPump and ventilator soft starters RSWT 75 mm/120 mm• Operational current: 12 to 45 A• Operational voltage: 220 - 600 VAC• Self-learning algorithm for optimised starts• Torque control during ramp-down• Compact dimensions: 45 mm wide housing• Optional: motor overload protection (Class 10)• Approvals: CE - cULus - CCC - EACGeneral purpose soft starters RSGD 45 mm
