Product Details

Soft starters with two-phase phase control, BA9018

Two motor phases are influenced by means of phase control using alternistors in such a way that the currents are able to rise steadily. The drive unit starts without jerking. Mechanical and electrical components are protected and the starting current is effectively reduced.
After starting, the alternistors are bridged via internal relay contacts, to minimise losses in the device.
The smooth deceleration function prolongs the natural deceleration time of the drive unit and prevents it from stopping abruptly.
The two-phase phase control makes these devices suitable for a wide range of applications, such as

Machines with gear, belt and chain drives
Conveyor belts, fans, pumps, compressors
Woodworking machines, centrifuges
Packaging machines, door operating mechanisms
Inrush current limitation for three-phase transformers


Smooth starting and smooth deceleration function
For motor ratings up to 5.5 kW / 11 kW
2-phase motor control
Starting time, deceleration time and starting torque can be adjusted separately
Control input
BA9018: Overall width 45 mm



  • The BA9018 may 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.
