Softstarter PF 9015
The new softstarter PF 9015 of the MINISTART family from DOLD is a robust electronic control unit for the soft start of motors up to 40 A with integrated monitoring functions and a width of only 67.5 mm. To operate the motor reliably, the PF 9015 offers soft start, motor protection, voltage and phase sequence monitoring in just one device.
The compact 3-phase controlled softstarter enables a smooth and gentle start (start-up time up to 20 s) due to a reduced starting current. The current peaks and torque shocks that interfere with switching are reduced. This increases the service life of the motors and mechanical drive components.
Monitoring the rotating field (clockwise) prevents motors from starting up in the wrong direction of rotation. The integrated undervoltage and overvoltage monitoring as well as the motor protection function according to Class 10 protect the motor against overload. The most important functions of the device include blockage protection in bypass mode, detection of missing load and integrated temperature monitoring of the power semiconductors. With the softstarter PF 9015, the user has a smart, user-friendly softstarter with extensive monitoring and protection functions.
