Cold water machine the role of the electronic starter, the impact of the current produced all kinds of starter can be up to five times the motor full load current.
If the electronic starter, then the impact current can be reduced, therefore, electronic starter is also known as soft starter.
This kind of starter use electronic circuit can reduce motor starting voltage and change the power frequency, the result can make a normal boot, locked-rotor current up to 1000 amperes motor can under the conditions of 100 amp locked-rotor current rapid start, and then accelerate, achieve the rated speed of the motor.
This way for all the other boot device are much more convenient, and the impact on the current voltage fluctuation is greatly reduced.
in addition, the electronic starter does not need to have a touch off the top of the above all kinds of starter advantages.
