RSBD and RSBT are easy to use soft starters for scroll compressors up to 95Amp nominal current. The units are equipped with a patented auto-adaptive algorithm that automatically adapts itself to the specific compressor it is controlling ensuring that an optimum inrush current reduction is achieved. RSBD is a 2- phase controlled and RSBT is a 3-phase controlled solution with integrated bypass relays for bypassing of the semiconductors after ramp-up. The unit is supplied inside housing and can be DIN or panel mounted (accessories included). RSB. soft starters include also 2 changeover relays for bypass and alarm indication. The units have a maximum operating temperature 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 variables that can be transmitted to a host control system.
