Common problems with ultrasonic vibrating screen power supply: 1: The code of the power box is disordered. 2: E1 code appears. 3: The ultrasonic power supply is not powered on. 4: The frequency modulation vibration is not obvious when power is turned on. 5: When the power is turned on, the transducer vibrates. When these kinds of problems occur, most of them are caused by the failure of the ultrasonic electric board; there are many professional maintenance manufacturers, and professional technicians are needed to detect them. I recommend Xinxiang Shengleite Machinery JCC-2 ultrasonic vibrating screen power supply for professional maintenance. I have repaired it several times. Not bad!
