| This not only saves space in the control cabinet and on the standard mounting rail but also does away completely with the wiring work needed for wye-delta starters |
| This is notable in particular for higher motor ratings which are only rarely available as fully wired solutions |
| Compact dimensions, short start up times, easy wiring and fast commissioning make themselves felt as clear-cut cost advantages |
| The bypass contacts of these softstarters are protected during operation by an integrated solid state arc quenching system |
| The new series of devices comes with the polarity balancing control method, which is designed to prevent direct current components in 2-phase controlled softstarters |
| On two-phase controlled soft starters the current resulting from superimposition of the two controlled phases flows in the uncontrolled phase |
| This results for physical reasons in an asymmetric distribution of the three phase currents during the motor ramp-up, This phenomenon cannot be influenced, but in most applications it is non-critical |
| Controlling the power semiconductors results not only in this asymmetry, however, but also in the previously mentioned direct current components which can cause severe noise generation on the motor at starting voltages of less than 50 % |
| It creates a motor ramp-up that is uniform in speed, torque and current rise, thus permitting a particularly gentle, two-phase starting of the motors |
