Courtesy: Carlo GavazzCarlo Gavazzi's RSWT Series is a self-optimizing 3-phase pump soft starter, in which all three phases are controlled to achieve current balancing on all phases, to minimize vibrations during starting and stopping of centrifugal pumps, and to minimize the inrush current. They are designed for agriculture, water treatment, and HVAC applications. Through a dedicated self-learning algorithm, the RSWT Series achieves very smooth starting and stopping, with minimal setting adjustments required from the user. The self-learning routine is active at ensuing starts to ensure optimal starting and stopping parameters are used even if the load changes. This results in less water hammering and reduces the risk of cavitation. Two RSWT Series types are offered: the V00/V01 provides a single adjustment setting for the soft-starting and stopping time of the pump. The V10/V11 includes Class 10 overload protection and soft starting and stopping times that can be individually set for more accurate pump control.
