Description: This ZVS board set includes high quality 1.6mm double circuit board, large inducto r, accuracy metal film resistor, anti-static heat sink and high frequency resonant capacitors that ensures its stable performance. With a proper power supply and correct circuit, you can create a beautiful electric arc by yourself. This is a popular kit and you can buy one for yourself or give one to your electronics hobbyist friend as a gift. Features: 1. High quality 1.6mm double circuit board, extra tin for power wire and optimize the wire size of MOS tube driving circuit with a higher current-carrying capacity and better heat dissipation. 2. Two original IRFP260N mosfets ensure large current, small internal resistance, high power and better performance. 3. Professional factory custom large inductor(1.2mm copper wire), fine workman ship and stable performance, could connect to 15A current for longer time. 4. Employ 1% accuracy 3W metal film resistor with less error, higher precision, small temperature drift and good heat dissipation. 5. Big thick anti-static heat sink, better heat dissipation effect, greatly improve the stability and service life. 6. Two custom made MKP 0.33 UF 1200V in parallel as high frequency resonant capacitors have large capacity. Specifications: Size: 13 x 8.8 x 4.3cm / 5.12 x 3.46 x 1.69" Input Voltage: 12V - 30V DC Current: ≥5A(if 15V) Frequency: 30KHZ - 50KHZ(self-adaptive) Secondary Parameter: 5T+5T Electric Arc Length: When input is 12V / 5A, the length of electric arc is about 1-2cm. The more input voltage and current, the greater output power, the longer electric arc. The highest input is 30V / 10A, and electric arc can be 5 cm or more.If the arc is too short, please check if input power is sufficient. Power Supply: If you use battery as power supply, model airplane battery with more than 25C discharge rate is suggested. Please do not use ordinary battery of electric vehicles.If you use the switched-mode power supply, use one of 12V and current should be more than 5 A. 24V switched-mode power supply(or linear power supply) should provide current more than 15A. If current is not sufficient, the tube will be breakdown. Power: The output power depends on input power. If you use a 30W power supply, even with a 200w ZVS the output power won't reach 100W. So the input power of power supply must be sufficient. Power = voltage * current. If you use a high power switched-mode power supply, please note it may have a soft start function, namely circuit minimizes large startup currents from flowing when the input power is first applied. Now suppose that ZVS circuit is connected before the voltage reaches up to 12V, electrical resonance will not occur because of a low starting voltage, lead to two MOS tube break-over at the same time and burned component. So start up the switch power supply first, and connect to ZVS circuit after the voltage reaches 12V.
