Advantage:

Comprehensive protection motor

Highly integrates protection functions of motor, so that the design, installation is simpler, reliable, and make a machine to be multi-function. If the input voltage is too high, too low protection; lack of phase of the input and output , three-phase imbalance protection; load over-current, overload, short circuit protection.

Intelligent:

After the traditional soft-start settle orders of time and the starting voltage value, no matter how light and heavy load, the program will finish the progress of soft-start in accordance with the order of setting time. And the caused unnecessary waste of the equipment while a light load, such as some equipments do not allow low-voltage start long time; While heavy load, the accumulation of time causes the damage of the soft starter component.SJR2 completely avoid the artificial defects, it can use the way of induction of the load to start the soft starter.

The appearance:

The design creates a beautiful appearance, and makes the mechanical structure to become better. The pedestal, radiator and shell of SJR2, were made by the aluminum alloy casting, and make a more reasonable and effective solution to the soft starter power component cooling problem; beautiful shell increases the overall quality, and make people feel comfortable, noble, elegant soft starter.

The design of circuit board:

Soft starter design

The general wiring of the main control board of the soft starter is the upper and lower levels, and the wiring of the main control board of SJR2 add to four. Therefore it reduces the volume and increases the functions, increases the whole anti-interference ability significantly, and more applicable to be used in different environments.
