Soft Starter 2-Phase and 3-Phase Scroll Compressor Softstarter Types RSBD48..CV. (2-Phase), RSBT48..CV. (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) - optional Product Description Ordering Code RSB T 48 55 C V0 RSBD 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.
