RSGD is an extremely compact and easy to use 3-phase soft starter for AC induction motors. Rated up to 45AAC the RSGD is offered in a 45mm wide IP20 housing that can be DIN or panel mounted. RSGD controls two phases and is internally bypassed to reduce the heat dissipation inside the panel. The series up to 400V (RSGD40..) is also internally supplied. Through its micro-controller based algorithm, the RSGD achieves an exceptional inrush current reduction resulting in smoother starting and stopping of motors. The starting parameters can be easily set-up through a 3- knob user interface and LED indications are provided for indication of supply, alarm and ramping/bypass status. RSGD provides a number of diagnostic functions including phase sequence, over- and under-voltage monitoring and locked rotor protection. Optional relays for alarm and bypass indication are provided as an option. For higher starts/hr, the RSGD 37A and 45A versions can also be equipped with a fan which is available as an accessory.
