About Soft Starters:

Soft Starter is a device that starts motors with reduced power supplied at start-up. Reducing the power reduces potentially damaging electrical and mechanical shocks on the system.

How Soft Starters work:

As the name implies, Soft Starters "start" motors, but can also stop, reverse, accelerate and protect them. A Soft Starter is a controller with overload protection.

Soft Starter Benefits

Advantages of Soft Starters include the following:

  • Reduces start-up current and peak demand and subsequently reduces energy costs;
  • Voltage or current is applied gradually, without the voltage and current transients;
  • Closed loop control to ensure start-up success for different conditions and different loads;
  • Protects against low/high voltage/current, overload, short-circuit, lost phases (in/out) and 3-phase imbalance;
  • Improved power factor at all load cycles and thereby a reduction in kVA;
  • Reduces power surges and heating of motors and improves operating efficiency and service life of mechanical equipment;
  • Possibility of increased number of starts per hour;
  • Reliable performance even if load characteristics vary between starts (e.g. loaded or unloaded starts);
  • Adjustable acceleration time with smooth acceleration without the torque transients;
  • Elimination of starting mechanical shock to couplings and driven equipment;
  • Increased contact life of starter contactors;
  • A single starter can start multiple motors with optional starting parameters;
  • Easy adjustment of start performance to suit the specific motor and load.
