AST series soft-starter is a new generation of high reliability, high cost performance motor control equipment designed by AEG by making full use of its own hundred years of power electronics technology and experience, which integrates soft start, soft stop, light load energy saving and multi-function protection. The motor can be started smoothly without impact during the whole starting process, and various parameters, such as current limit value and starting time, can be adjusted according to the characteristics of the motor load during the starting process.

AST soft-starter has a wide range of applications, suitable for AC 380V, motor power from a few kilowatts to 320kW, especially all kinds of pump load or fan load.

• Integrating soft start, soft stop, light load energy saving and multi-function protection, it can adjust various parameters during the starting process according to the characteristics of the motor load, so as to realize the smooth starting of the motor without impact during the whole starting process

• Various starting modes: voltage ramp starting, current limiting starting, voltage ramp + current limiting starting, current ramp starting, pulse collision + voltage oblique starting, point moving

• Perfect protection functions: fast break, over current, operation phase loss, overload, current imbalance, under/over voltage, overheating protection, blocking protection, etc

• Large LCD display, Chinese/English display interface is optional

• With RS485 communication function, through the bus, topology and other ways to centralized monitoring of multiple devices, can be soft starter parameter setting, operation, signal and fault monitoring, so as to achieve a high intelligent remote monitoring of the soft starter
