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
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
Features
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
