The RSWT Series is a 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. Through a dedicated self-learning algorithm, the RSWT Series achieves very smooth starting and stopping, with minimal setting adjustments required from the user. Within three to six starts, the RSWT Series reaches optimization. On a positive note, 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, whereas the V10/V11 includes Class 10 overload protection and soft starting and stopping times that can be individually set for more accurate pump control. With the launch of the RSWT Series, CARLO GAVAZZI has further strengthened its soft starter portfolio, by offering yet another ideal solution, directed at a specific application for markets such as agriculture, water treatment, and HVAC.
