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.
