High performance Soft Starter for low-voltage three-phase asynchronous motors

The ASAB is an advanced digital solution for the soft starting of motors ranging from 7.5kW to 800kW. The ASAB soft starters provide a complete range of protection functionality for motors and industrial plants, ensuring reliable and high efficiency performance in the most complex applications requiring motor soft starting/stopping. In addition to the Constant Current and Current Ramp starting/stopping, the ASAB implements the Adaptive Acceleration Control function featuring three different starting/stopping profiles to fulfil the requirements of any application.

Mains power supply:
380 Vac to 600 Vac ± 10% (in-line or inside-delta connection)
380 Vac to 690 Vac ± 10% (only with grounded star point installation)

Control circuit power supply:
110 to 120 Vac (+10%/-15%)
220 to 240 Vac (+10%/-15%)
24 Vac/Vdc ±20%
