(3-Phase)• Soft starting of 3-phase Scroll Compressors up to 95 Amp• Patented auto-adaptive algorithm for optimum inrush current reduction (No user-settings required)• Integrated bypass relays• 2- (RSBD) and 3-phase (RSBT) controlled solutions• Multi-voltage operation (220 – 480VAC, 50/60Hz)• Rated operational current: 55, 70, 95AAC• Phase sequence and undervoltage monitoring• Overtemperature, Overcurrent, Locked Rotor protection• Changeover relay outputs for bypass and alarm indication• UL, cUL, CE, RoHS compliant• Current balancing strategy (RSBD models)• RS485 serial communication port (MODBUS-RTU) - optionalProduct DescriptionOrdering CodeRSB T 48 55 C V0RSBD and RSBT are easy to use softstarters for scroll com- pressors up to 95Amp nomi- nal current. The units are equipped with a patented auto-adaptive algorithm that automaticallyadapts itself to the specific compressor it is controlling ensuring that an optimum inrush current reduc- tion is achieved. RSBD is a 2- phase controlled and RSBT is a 3-phase controlled solution with integrated bypass relays for bypassing of the semicon- ductors after ramp-up.The unit is supplied inside housing and can be DIN or panel mounted (accessories included). RSB. softstarters include also 2 changeover relays for bypass and alarm indication. Theunitshavea maximum operating tempera- ture of 60˚C (with derating from 40˚C).RSB.CVC versions are equipped with a Modbus RTU serial communication for start and stop and communication of relevant instantaneous vari- ables that can be transmitted to a host control system.Compressor Softstarter Controlled phases Operational VoltageRated Operational CurrentControl VoltageVersionType SelectionType Rated operationalRated operationalControl voltageVersions voltage Ue Current IeUcRSBD 48: 220 - 480VAC55: 55ArmsC: 24VAC/DC ±10% V0 : 2x ChangeoverRSBT-15%, + 10%70: 70Arms and110 - 400VAC relay outputs95: 95Arms-15%, +10% VC: RS485 MODBUSserial communicationSelection GuideNo. of TypeOperationalControlVersionRated Operational Current ControlledVoltagevoltage55AAC70AAC 95AAC Phases2RSBD 220 - 480VAC 24VAC/DC 2 Changeover RSBD4855CV0 RSBD4870CV0RSBD4895CV03RSBT&Relay Outputs RSBT4855CV0RSBT4870CV0RSBT4895CV0110 - 400VACRS485 SerialRSBD4855CVCRSBD4870CVC RSBD4895CVC communication RSBT4855CVC RSBT4870CVC RSBT4895CVC (MODBUS RTU)Specifications are subject to change without notice (21.11.2014)1
