Product description

Softstarts are electronic devices designed to enable 1-phase or 3-phase induction motors to start smoothly. IR 9027 slowly ramps up the current on two phases, therefore allowing the motor torque to build up slowly. This reduces the mechanical stress on the machine, prevents damage to conveyed material and limits the start current. When the motor is up to full speed the semiconductors in IR 9027 are bridged to prevent internal power losses and heat build up.
