Features: DC12-36V input (recommended 24V), voltage is about 1000 times the input voltage. The 12V input power can reach 50-100w, and the 24V input power can reach 200w or more, so the power supply current is required to be above 10A. The flyback drive circuit is used to drive the ignition coil, just like a voltage switches, and a large number of fans are called "ZVS circuits". Due to its power, low heat generation, it is widely used by fans to drive spark coils (SGTC) and Jacob, ladder, Marx generators, etc. Come with low resistance, low heat generation, good heat dissipation, greatly improving stability and lifespan. To prevent excessive current at the bottom, the whole window add tin treatments, bring strong overload capacity, has the characteristics of power, low heat, simple and practical. Specifications: Material:ABS Package Includes: 1Piece ZVS Coil Driver Board 1Piece Ignition Coil note: Please allow 1mm errors due to manual measurement.
