A compact and cost-effective soft starter

An extremely cost-effective and compact soft starter that provides basic soft start and stop functionality and easy DIN rail mounting.

The ‘fit and forget’ semiconductor design simplifies installation and reduces required panel space, and selection can be made on the basis of the motor power. Timed voltage ramp up and down are possible. Ramp time can be individually and accurately adjusted with rotary switches from 0.4–10 seconds, and starting torque can be adjusted from 0–85% of the direct on-line torque.

Supply voltages and power range 

  • 3 x 208-600 V…0.1-11 kW (25 A)
  • 24-480 V AC or DC
