Product Characteristics

1、Series resonance device features such protection functions as over voltage over current zero start system dissonance (flash falling) etc. The overvoltage and over current protection value can be adjusted according to user needs try to taste flash falling protection action and can write down the flash falling voltage for test analysis.

2、The whole Series resonance device has a very light weight the maximum weight is no more than 40kg easy for scene use.

3、Series resonance device features four work modes convenient for users to flexibly choose according to scene conditions and improve test speed.
