Product description

The PF 9015 of the MINISTART family is a robust electronic control device for softstart and softstop of 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.

Technical specifications

Widths: 67,5 mm
Load voltage up to: 3AC 480 V
For three-phase motors, 400 V up to: 7,5 kW
Auxiliary voltage required: Yes
Signalling output: Yes
Extra functions: Temperaturüberwachung
Type: PF 9015

Advantages

  • For starting current limitation and soft start of asynchronous motors
  • Only one small device 67.5 mm for softstart, motor protection, phase sequence, under- and overvoltage monitoring
  • Soft start and minimized staring current
  • Extended service life of AC - motors and mechanical drive system
  • For motor currents up to 20 A (up to 40 A on request)
  • Softstart, softstop 1 ... 20 s
  • Energy saving by bridging of the semiconductors after softstart
  • Symmetrical staring current
