Buy ZVS Tesla Coil Power Supply Boost High Voltage Generator Driver Board Induction Heating Module DIY Production Kit Product parameters: Product size: 74mm * 77.8mm; Shell size: 102*88*42.5MM; Input voltage: DC 12V-30V Power requirements: less than 12V ≥ 5A 15V or more ≥ 15A Operating frequency: 30kHz-50kHz adaptive Secondary parameter: 5T+5T About the length of the discharge arc: When the input voltage is 12v/5A, the arc distance of the high voltage discharge is about 1-2 cm. The larger the input voltage and current, the greater the output power and the longer the arc discharge distance. The maximum input is 30v/10A, and the maximum length is more than 5 cm. If the arc is too short, check if the input power is sufficient. Power supply selection: If the battery is used, use a model battery with a discharge rate of 25C or higher. Do not use an ordinary electric vehicle battery or a small battery. If you use a switching power supply, you should choose a 12V or more switching power suppl
