Model Item Name Width Ultrasonic Power Frequency Voltage; 5300: 40 Kilohertz (kHz) Standard Frequency, 250 Watt (W) Ultrasonic Power, and 120 Volt (V) Alternating Current (AC) Voltage Ultrasonic Generator. ultrasonic cleaning generator. This is lower than ultrasonic frequencies for medical equipment to. Skeptics will claim this is nothing more than pseudo-science. Dog Repeller Schematic no 1. If you hold the shift key at the same time, the frequency will change by plus or minus 10Hz at a time instead. Without the piezo the output voltage is around 200 Vpp. Used on a simple cleaning tank or in a fully integrated cleaning system, the Series 8500 will deliver precise cleaning quickly, consistently, and cost effectively. The transmitter circuit generates an ultrasonic frequency between 40-50kHz. High frequency ultrasonic generator. Ultrasonic digital generator and PCBs. I can NOT find a description of the sound that cats, dogs, and deer hate. It is used to producing in high frequency power circuit, and driving ultrasonic vibration parts. The power amplifier AP is realized using four power MOSFET transistors, in a full bridge, working in commutation at high frequency. Advanced microcomputer control technology and new circuit design concept applied in ultrasonic field, the new generation of multi-functional multi-frequency ultrasonic generator produced which are specialized in ultrasonic cleaner.
