Need to buy soft starter, selection should be how to choose?

1. Firstly, the motor is selected according to the motor name plate parameters.

First understand the motor model, rated voltage, rated power, rated stator current, rated rotor current, torque, frequency, etc.

2. Fully understand the load.

If it is light load, you can choose standard configuration.

Mechanical loads such as belt conveyor, ball mill, brick machine and crusher are heavy loads. In this case, increasing the capacity of soft starter can improve the service life of products. In the long run, it will reduce the maintenance cost.

3. Look at the quality of the power grid.

Due to different working principles, some soft starters have larger starting current when they work. If the grid voltage is low, they can only choose the ones with smaller starting current, such as magnetic control soft starter and frequency conversion starter.

In addition, the quality of power supply and the parallel operation of frequency converter and reactive power compensation device will cause the abnormal operation and even damage of soft starter, which should be paid attention to in the design and layout.

4. Pay attention to the starting times.

Some working conditions will require the motor to start frequently. Then the variable resistance starter, such as the water resistance cabinet which can only be started 3 ~ 5 times in a short time, can not be selected. If the load is large or the starting and stopping frequency is increased, the product with larger rating must be selected.

5. Fully consider the specific conditions.

The objective factors of soft starter operation environment, such as humidity, temperature, altitude, dust, etc., will affect the equipment capacity. For example, in high altitude areas, it is necessary to increase the capacity of the soft starter. Factors such as strong ultraviolet radiation in plateau areas and large temperature difference between day and night will cause premature aging of electronic components. Therefore, it is necessary to increase the capacity.

6. Combined with their own design.

Motor soft starter manufacturers usually do not stock, soft starter is mostly based on their own design, such as: one drag more, one drag one choice.

Finally, the budget matters. Each price can be matched to the appropriate soft starter. Of course, every cent of the price is every cent of the goods.

Safesave soft starter is cheap and of good quality. It can provide the best quality products with the most favorable and suitable price to serve the customers.
