In December, C&A has announced the launch of a new and innovative product, Soft Starters, and added yet another product in their offering basket. As a leading supplier of AC Drives, C&A is all set to increase its standard product market penetration and spread in India. In line with this strategy C&A is expanding its range and has launched two separate Soft Starter series, SUPERNOVA and IMS2 Series. These are available in the range from 7.5kW to 800 kW.

Soft start is a technology used to start induction motors gently. Soft starting accelerates the motor more smoothly than direct on-line (full voltage) starting or other forms of reduced voltage starting.

Soft start works by controlling the amount of current delivered to the motor while it is starting. This prevents current transients and supply disturbances. Soft starting also limits the level of starting torque, extending the acceleration period and enabling the motor to build up to full speed more gently. Soft start offers electrical, mechanical and economic benefits.

Electrical benefits

Soft starting controls the current surge at start, preventing voltage dips and surges on the electricity supply. Soft starters can reduce electricity charges by reducing the demand peak associated with direct on-line motor starting. By reducing the electrical extremes experienced by equipment, soft starting can reduce electrical damage such as pitting or erosion of contacts.

Mechanical benefits

Soft starters prevent torque transients. The high torque transients that occur with traditional electromechanical starting methods can damage the motor, load, transmission and coupling equipment.

Soft starting reduces excessive wear on components including pipes, valves, couplings and bearings. Soft starting and stopping also prevents damage to products car ried on conveyors, which can be jolted and broken by sudden movement, and can reduce damage to fluid systems from water hammering..

Economic benefits

Reducing the electrical and mechanical strain on the motor and the load reduces the risk of damage. Soft start can reduce the amount of maintenance required, minimising maintenance costs and production downtime.

By limiting the extremes of current and torque at starting, soft starting can reduce the headroom required in system specifications. This allows systems to be constructed more conservatively (for example, smaller shafts, bearings, pipes and valves).

Soft starting can enable use of larger motors on limited supplies, such as generator sets. Starting the same motor direct on-line would require a larger and more expensive generator.

IMS2 Series

IMS2 Series Soft Starters are a total motor starting solution. They include all the functionality expected from an advanced and technically superior soft starter. IMS2 soft starters retain motor protection and monitoring functions even when soft starter is bypassed. These can be connected to the motor in 6 Wire or inside delta configuration enabling the starter to control motors 50% larger than possible with standard 3 Wire connection.

SUPERNOVA Series

The SUPERNOVA Series Soft Starters provide soft start and soft stop control for new or existing motors.. The starters are compact and reliable, and feature a built-in bypass contactor to reduce heating during run. This makes SUPERNOVA ideal for installation into switchboards or starter enclosures.

While SUPERNOVA CSX soft starters are ideal for soft starting motors having external motor protection, the CSXi soft starters provide complete motor control solution in a compact design.
