AEG AST soft starter is a motor control equipment for AC 380V applications, featuring soft start/stop, energy saving, and protection functions.
The AEG AST soft starter is a high-reliability motor control device designed for AC 380V applications, suitable for motor powers ranging from a few kilowatts up to 800kW. It integrates soft starting, soft stopping, light-load energy saving, and multi-function protection, making it particularly suitable for pump and fan loads. The device utilizes thyristors in series with the motor stator circuit, controlled by a microprocessor to adjust the firing angle and regulate input voltage for smooth motor startup without impact.
