Product description
The softstarter PF 9415 from the MINISTART family is a robust electronic control unit for ambitious start-up and deceleration 3-phase / asynchronous motors with integrated monitoring functions. After softstart the semiconductors are bridged by relay contacts to reduce the power dissipation in the unit. Motor start via control input or Modbus RTU, parameter dependent.
