model was designed with an increased power consumption (from 9W to 30W in some iterations) to improve the efficiency of the ultrasonic emission into the liquid. Key Components : Transistor Стир

: It is dangerous to put hands in the water while an ultrasonic device is active, as it may damage small blood vessels (capillaries).

: A frequent point of failure; it is often replaced with a 12kΩ (0.125W) resistor during repairs. Diodes : Frequently used parts include the or . : It is dangerous to put hands in

Retona USU-0707 " is a compact ultrasonic washing device consisting of a power supply unit and a small piezoceramic radiator (activator). The device works by emitting ultrasonic waves into water to dislodge dirt from fabric fibers.
