Product Description

Product Overview 

      RZMV series medium voltage solid state soft starter device is the latest generation of perfect, reliable and convenient maintenance of high-tech products. It is mainly used for starting and stopping control and  protection of squirrel cage asynchronous synchronous starter.The device adopts a number of thyristor series and connected, can meet the current and voltage requirements .

      They are widely used in rated voltage 3000-10000V power ,building materials ,chemical, metallurgy steel , paper making and other industries .it is the ideal medium voltage motor starting and protection equipment for mercury water,blower compressor, grinder mixer,Pitty machine and other mechanical equipment.

Device Introduction

     Medium voltage soft starter is a new intelligent motor starter, it is suitable for squirrel-cage asynchronous and synchronous motors. It is a Integrated motor terminal control equipment of starter, display, Protection, data collection . Users can achieve more complex control functions by using fewer components. The medium voltage soft starter controls the input voltage through the conduction Angle between the control items in order to change the voltage value at he starter end of a motor, that is, control the starting torque and starting current of the motor to realize the motor soft start control. Medium voltage soft starter can accelerate smoothly according to the set starting parameters, thus reducing the electrical and mechanical impact on the power grid, motor and  equipment. When the motor reaches the rated speed, the bypass contactor is switched on automatically. The medium voltage soft starter continues to monitor the motor after starting and provides various fault protection.

Technical Characteristics
