Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors. The control of the voltage applied to the motor by means of adjustments to the firing angle and thyristors allows the soft-starter to start and stop an electric motor smoothly.
The SSW07 with DSP ( Digital Signal Processor) control was designed for high performance on motor starts and stops with an excellent cost-benefit ratio. Easy to set up, it simplifies start-up activities and daily operation.
The SSW07 is compact optimizing space in electrical panels. It already incorporates electric motor protection. It adapts to customer needs through its easy-to-install optional accessories. The SSW07 adapts to customer needs through its easy-to-install optional accessories. Thus, a keypad, a communication interface or a motor PTC input can be added to the product. SSW07 Soft-Starter Series were designed for exclusively industrial or professional use.

The 7-segment LED display provides excellent visibility of the parameters. It also incorporates the copy function, which allows you to copy the parameter setting from one SSW07 to another, providing programming agility, reliability and repeatability in the manufacturing process of serial machines.
Especially designed to integrate large industrial automation plants, the Fieldbus communication networks provide advantages in the complete, on-line supervision, monitoring and control of the SSW07, producing high performance and great operational flexibility, characteristic required by applications on complex and/or integrated systems.
The three-phase voltage control on the SSW07 allows its use in applications considered heavy, such as alternate, centrifugal pumps (sanitation, irrigation and oil), fans, exhauster, blowers, air compressors, refrigeration (screw and piston), mixers, aerators, centrifuges, rock crushers, grinders, woodchippers, paper refiners, rotary ovens, wood saws and planes, ball and hammer mills and load conveyors.
