Product description

The BA 9010 and BN 9011 are electronic devices designed to enable 1-phase or 3-phase induction motors to start smoothly. BA 9010 / BN 9011 slowly ramps up the current on one phase, therefore allowing the motor torque to build up slowly. This reduces the mechanical stress on the machine and prevents damage to conveyed material. When the motor is up to full speed the semiconductors in BA 9010 / BN 9011 are bridged to prevent internal power losses an heat build up.
