Soft starters deliver more torque with less vibration
Soft starters in the new DS7 range from Eaton's Electrical Sector combine smooth starting and freedom from vibration, previously only available from three-phase units, with the economy and space savings of a two-phase soft starter. In addition, as fully integrated elements of the Eaton xStart motor control range, they offer the convenience of fast, simple tool-free connection with motor protection relays and circuit breakers.
DS7 soft starters, which are available with ratings from 1.1kW to 15kW on 400V three-phase supplies, feature a patented asymmetric triggering system that eliminates DC components in the supply to the motor during starting. This ensures smooth starting, allows the units to deliver more starting torque and reduces motor heating. The low level of motor vibration during starting also minimises wear on mechanical components, extending their lives and reducing maintenance requirements.
