Feature: 1. Use a flyback drive circuit such as no voltage switch to drive the ignition coil 2. To prevent excessive current at the bottom, the whole window add tin treatment, bring strong overload capacity, has the characteristics of high power, low heat, simple and reliable 3. This set use good-quality graphics radiator, which bring good heat dissipation effect 4. ZVS improved the stainless steel material and use FR4 double-layer glass fiber board to produce 5. Come with low resistance, low heat generation, good heat dissipation, greatly improving stability and lifespan Specification: Item Type: ZVS Driver Board Coil Power Supply Material: Plastic + fiberglass Model: ZVS Application: Widely used to drive spark gap coil, for Jacob's Ladder, for Marx Generator and other devices Input Voltage: DC12-30V Input Current: More than 10A (15A-20A recommended). Package List: 1 x ZVS Driver Board1 x Coil Power Supply Note: 1. Please pay attention to the positive and negative signs of the power supply at the input end of the driver board, check and confirm before turning on the power to prevent reverse burning of the board2. The test machine voltage is recommended to be a low power 12v, to prevent problems or wrong wiring causing burn‑in3. The limit input of the drive board is DC 30v, current 20A, it is not recommended to use the limit value, please do not run for a long time under the condition of overvoltage and overcurrent4. Please note that the new type and old type of this product will be sent randomly,and make sure you will not mind before ordering.
