BA9026 3AC50/60Hz 200-460V 3kW Dold 3 kW Soft Starter, 460 V ac, 3 Phase, IP20, IP40

Soft starter, BA9026_x000D_ All three motor phases are influenced by the BA9026 by means of phase control using thyristors in such a way that the currents can rise steadily. The motor torque behaves in exactly the same way during start-up. This guarantees that the drive can start up without jerking. It is thus impossible for drive elements to be damaged, because the abrupt starting torque caused by direct starting is not generated. This property enables a cost-efficient design for the drive elements._x000D_ After starting, the power electronics are bridged via internal relay contacts to minimise losses in the device._x000D_ The smooth deceleration function also prolongs the natural deceleration time of the drive unit to prevent abrupt stopping._x000D_ Applications_x000D_ Machines with gear, belt and chain drives_x000D_ Conveyor belts, fans, pumps, compressors_x000D_ Woodworking machines, centrifuges_x000D_ Packaging machines, door operating mechanisms_x000D_ Inrush current limitation for three-phase transformers_x000D_ Features_x000D_ With smooth deceleration function_x000D_ Increases the service life of asynchronous motors and mechanical drive components for motor ratings up to 3 kW_x000D_ With 3-phase motor control_x000D_ Starting time, deceleration time and starting and deceleration torque can be adjusted separately_x000D_ Power semiconductors bridged after successful start-up_x000D_ Large input voltage range for the power semiconductors_x000D_ Galvanically isolated DC control input_x000D_ Galvanically isolated DC auxiliary voltage_x000D_ With integrated temperature monitoring_x000D_ Overall width 45 mm_x000D_ Warning_x000D_ The BA9026 must not be operated with a capacitive load (e.g. reactive power compensation) at the output. In the decoupled state (without load), the starting behaviour is not particularly smooth._x000D_
