90kw soft start stainless steel power distribution board 440V 200 400 amp electrical panel motor start stop control cabinet
The soft start control cabinet is an electrical device used for motor starting control. It provides a smooth starting process by reducing the current impact when the motor starts, thereby protecting the motor and the power grid, extending the service life of the equipment, and improving energy efficiency.
It is widely used to receive high and low water level control signals output by liquid level controller, control the automatic switch of liquid pump motor, and various control forms such as full-voltage starting, reduced-voltage starting, soft starting, frequency conversion control, etc., to reduce starting current, reduce current shock and mechanical shock when the motor starts, improve power quality, save energy, and at the same time have stall protection and fast protection functions to prevent motor overheating and burning, reduce wear and tear, and extend the service life of the motor.
Classification by voltage: divided into low-voltage soft start cabinet and high-voltage soft start cabinet.
Classification by load: such as fan soft start cabinet, water pump soft start cabinet, etc., select the corresponding soft start cabinet according to different load characteristics.
According to the control mode: there are one-to-one soft start cabinet, one-to-multiple soft start cabinets, one-in-use and one-in-standby soft start cabinet, etc., select the appropriate control mode according to actual needs.
