Features:Power tube: power tube;PCB: double-sided two ounces;Stable performance;Large radiator, cooling fast. Shock circuit board (ceramic transducer) Wiring instructions: 1.The board can not load electricity.2.No cleaning solution can not be energized cleaning.3. first two tabs, two ceramic middle lug is positive,by the upper and lower metal column is negative,can not be reversed 4.Transducer film on the ceramic sheet covered with a silver layer for the negative side,the other side of a large two silver layer is positive,the smaller one for the negative plate,welding power cord must be welded to the side of the silver layer has two,the other side of the vibration can be pasted (this is available with a ceramic patch transducer assembly instructions) in a bidet; a silver layer ceramic chip is not high temperature, when the welding power line iron temperature should not exceed 280 degrees,most good use heated iron,the iron temperature is set to 250 degrees.5.Shock larger side (with screw holes) to vibrate can be glued to the pelvic floor cleaning,washing pots must be well grounded.6.Shock or transducer ceramic glue application shock stick firmly to the pelvic floor cleaning 7.Two shock and coupled to the circuit board terminal,a circuit board with up to two shock ,but also with supporting the use of a shock .8. Circuit board wiring diagram is as follows:Positive and negative,respectively positive and negative output coupled with the shock of the child,can not pick the wrong,we have questions,timely advice to Suitable For: Ultrasonic cleaning machines.
