SST-NX is a compact soft starter developed based on two-phase thyristor voltage regulation control algorithm. It has the technical characteristics of small size, high integration, simple use and convenient deployment. As one of the company’s multiple soft starter product lines, the SST-NX series will solve application pain points such as cumbersome wiring of electrical equipment and inability to effectively arrange circuits due to compact space. It has unique advantages when applied to the electrical requirements of compact space low power consumption and low heating requirements, and rapid deployment.

1.Compact Design: Mini body carries robust soft starter functions.
2.Built-in bypass: customers don’t need to configure additional bypass contactors and the wiring is simpler and more convenient.
3.Protection functions :it has overload, under-load, overheating, phase loss, over-current protection functions as well as user-lock protection function.
4.Optional external panel: it provides convenient operation enabling users do personalized settings.
5.Voltage ramp start: compared with star delta starter, it realizes smoother start effect with the voltage ramp start function.

Knob of soft starting time: adjust soft starting time of soft starter and range is 1-20s.The longer the time setting, the more gentle the soft starting process, which is helpful to reduce the impact on power grid.
Knob of soft stopping time: adjust soft stopping time of soft starter and range is o-2oS.In some application occasions of water pump, soft stopping function can effectively avoid “water hammer effect” generated by the halt of water pump. When the knob is adjusted to be 0s, it indicates that the stalling way of motor is free stalling, which will stop output immediately after soft starting.
Knob of initial voitage: adjust initial voltage of soft starter and range is 40%~70%.When the motor starts, it needs to overcome the friction under stationary state. Properly increasing the initial voltage can obtain larger starting torque. The users should refer to actual load condition to coordinate starting and stopping time, thus obtaining the best effect of smooth starting.
