Product Description
product description
When a three-phase asynchronous motor is started directly, it will produce a large starting current, usually the current can reach 5-9 times the rated operating current. Such a large starting current will have a great impact on the power grid, and will also affect the life of the equipment. At the same time, the increase in the peak value of the power supply will cause additional transmission and distribution investment. Using a soft starter to start the motor can control and reduce the starting current to avoid the above adverse effects.
VSG100 series soft starter is a kind of all-digital intelligent starting equipment specially designed for three-phase asynchronous motors. It integrates microcomputer control technology, digital signal processing technology, thyristor control technology, and digital communication technology in the control of motor starting and stopping. It uses the working principle of current limiting or voltage slope rise to control the voltage output to the motor, thereby Limiting and reducing the starting current can not only guarantee the safe and reliable operation of the motor, but also realize remote monitoring and operation.
VSG100 series soft starters can be suitable for a variety of motor applications, such as the soft start and soft stop of fans, pumps and compressors driven by three-phase asynchronous motors. It can also be used to control equipment with variable speed mechanism, belt or chain belt transmission, such as ball mill, crusher, centrifuge, mixer, conveyor belt,
Grinding machines, planers, sawing machines, packaging machines and stamping equipment, etc.
The VSG100 series soft starter has the following advantages when applied to the transmission system:
●Reduce the starting current, reduce the peak current of the power supply, and reduce the cost of power distribution equipment
●Reduce motor loss and increase the service life of mechanical transmission equipment
●Adopting foreign advanced SCR control technology, low heat generation, smooth start and stop, stable control, suitable for heavy load occasions in the industrial field
●Using the soft stop function, the load can be smoothly decelerated and the water hammer effect of pump loads can be eliminated
●Provide multiple protection functions such as overcurrent, overload, undervoltage, overvoltage, and lack of equality, effectively protecting the motor starting and running
●Specially designed power-down memory electronic overload protection function, not affected by power-down, can replace thermal relay
●Adopt digital panel operation display, rich interface, intuitive use and easy operation
●With standard communication interface, remote monitoring is possible. Operate the starter and motor
