Description
A soft starter ELM250 series is an electronic device used to gradually start and stop electric motors, providing a controlled acceleration and deceleration of the motor is speed. Unlike direct-on-line DOL starters that deliver full voltage to the motor during startup, soft starters gradually increase the voltage to the motor over a specified time period, reducing the initial inrush current and mechanical stress. Soft starters are commonly used in applications where a sudden and high current draw could lead to voltage drops, mechanical wear, or other issues. During startup, the soft starter gradually increases the voltage applied to the motor is terminals. This leads to a controlled acceleration of the motor is speed. The voltage increase is achieved by using solid-state electronics to regulate the power delivered to the motor. Soft starters are commonly used in a wide range of industrial applications, including conveyor systems, pumps, fans, compressors, and more. They provide a cost-effective way to achieve controlled motor acceleration and deceleration without the high inrush currents associated with direct-on-line starting.
