IR9027 AC400V 5.5kW Dold 5.5 kW Soft Start, 400 V ac, 2 Phase, IP30

Soft Starter, IR9027_x000D_ Soft starters are robust electronic control devices for starting three-phase asynchronous machines smoothly. Two of the three motor phases are influenced by the IR9027 by phase control in such a way that the current in these phases rises steadily. The motor torque behaves in exactly the same way during start-up. This guarantees that the drive can start up without jerking._x000D_ It is impossible for drive elements to be damaged, because the abrupt starting torque caused by direct starting is not generated._x000D_ A marked reduction of starting noise is also perceived. Slippage or tipping over of items being conveyed on belts is avoided._x000D_ After starting, the power electronics are bridged via an internal relay contact to minimise losses in the device._x000D_ Applications_x000D_ Machines with gear, belt and chain drives_x000D_ Conveyor belts, fans, pumps, compressors_x000D_ Packaging machines, door operating mechanisms_x000D_ Features_x000D_ Increases the service life of asynchronous motors and mechanical drive components_x000D_ Easy installation even in existing systems_x000D_ No need for a neutral conductor_x000D_ Starting time and starting torque can be adjusted separately. Can be combined with motor brake units._x000D_ An f/V converter is frequently not needed for simple applications_x000D_ 2-phase control of the motor_x000D_ For motor ratings up to 5.5 kW_x000D_ Power semiconductor bridged after successful start-up_x000D_ LED display_x000D_ Suitable for snapping onto a 35 mm standard top-hat rail_x000D_ 105 mm overall width_x000D_ Warning_x000D_ The IR9027 requires a clockwise rotating field and 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_
