RSGD4016E0VD20 is a compact three-phase soft starter designed for AC induction motors, providing soft starting and soft stopping functions to reduce starting current and minimize mechanical stresses. This 45mm wide unit features a rated operational current of 16 Arms at 40°C, an operational voltage range of 220-400 VAC (+10% -15%), and a control voltage of 110-400 VAC. The soft starter incorporates a self-learning algorithm that automatically adjusts start parameters, with adjustable ramp-up time of 1-20 seconds and ramp-down time of 0-20 seconds. It features dual phase control, no heatsink configuration, 2 relay outputs, and is housed in a PA66 material enclosure with IP20 protection grade. Typical applications include compressors, pumps, and fans where controlled motor starting and stopping is required.
