RSBT4025EVC1HP, Soft Starter 3 Phase Scroll Compressor Soft Starter RSBT Models, RSBT4025EVC1HP, RSBT is a soft starter for Scroll compressors up to 95A rated current. They are equipped with an adaptive algorithm that makes the starter automatically adapt to the compressor it is controlling, ensuring an optimal reduction of the irruption intensity. RSBT controls three phases, both with integrated bypass relays to reduce heat dissipation within the panel. This controller does not include protections against short circuits or overload so they must be installed externally and with specific values., RSBT4025EVC1HP, Automatic adaptive algorithm (patented) RSBT include an innovative automatic adaptive algorithm (patented) that ensures an optimal starting intensity at each compressor start. This feature is active at every compressor start.. The soft starter automatically sets the appropriate parameters to perform an optimal reduction of the inrush current, while maintaining an upward ramp time of <1s. In case of rotor lock alarm/up ramp time, the parameters set by default are automatically reset. During successive compressor starts-ups, the automatic adaptive function will be activated by optimizing these parameters automatically once again. Specific operating mode of HP RSBT starters must attempt a soft start of the compressor within the specified intensity range. Depending on the load requirements, the intensity limit will gradually increase to a default maximum intensity limit, then RSBT will move into bypass mode. If the ramp does not run after a maximum of 1 second, the incomplete ramp alarm will be triggered (5 flashes of the red LED) and the RSBT starters will go into recovery mode for 5 min. If with the second consecutive attempt, RSB..HP the incomplete ramp alarm is triggered again, user intervention will be necessary to zero the RSBT feed, as it may indicate a real locked rotor condition.
