: The ultrasonic generator should never be switched on without the piezo-emitter submerged in water , as running it "dry" can destroy the circuit.
: Features a standard step-down transformer followed by a diode bridge (e.g., VD2–VD5) for rectification, providing a pulsating voltage of approximately 9V to 12V. Key Components : Transistor : The ultrasonic generator should never be switched
: It is dangerous to put hands in the water while an ultrasonic device is active, as it may damage small blood vessels (capillaries). VD2–VD5) for rectification
