Soft Starter, IR9027


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.

It is impossible for drive elements to be damaged, because the abrupt starting torque caused by direct starting is not generated.

A marked reduction of starting noise is also perceived. Slippage or tipping over of items being conveyed on belts is avoided.

After starting, the power electronics are bridged via an internal relay contact to minimise losses in the device.

Applications


Machines with gear, belt and chain drives

Conveyor belts, fans, pumps, compressors

Packaging machines, door operating mechanisms

Features


Increases the service life of asynchronous motors and mechanical drive components

Easy installation even in existing systems

No need for a neutral conductor

Starting time and starting torque can be adjusted separately. Can be combined with motor brake units.

An f/V converter is frequently not needed for simple applications

2-phase control of the motor

For motor ratings up to 5.5 kW

Power semiconductor bridged after successful start-up

LED display

Suitable for snapping onto a 35 mm standard top-hat rail

105 mm overall width

Warning

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.
