The common problems of ultrasonic cleaner generator are as follows:
(1) when the power switch is turned on, the indicator light is not on. In this case, it is necessary to check whether the power switch is in good condition and whether the leakage switch is closed. If the switch is in good condition, check whether the fuse is overloaded and blown, which can be basically solved.
(2) after the power switch is turned on, the indicator light is on, but there is no ultrasonic output. This situation is more complex. First, check whether the connection plug between the transducer and the ultrasonic power board is loose, and then check whether the fuse is blown. If everything is normal, it may be the internal fault of the ultrasonic power generator. Use a multimeter to make the power line open, and whether the live wire is connected. After troubleshooting the generator, check whether the ultrasonic transducer is burnt out and whether it needs to be replaced.
(3) DC fuse of ultrasonic cleaning machine is blown. It may be that the rectifier bridge stack or power tube is burned out, or the transducer is aging and the current is unstable, which may cause the power generator failure. Pay more attention to maintenance.
