Function: 1. It can be used as a high voltage source for high school science experiments, electronic instrument, negative ion generator and small science. 2. By inputting a DC voltage of 3.0V-4.8V, a high DC voltage of about 10,000V (about 1-2cm of arc) can be output. 3. According to the tesla coil principle, the module outputs high voltage pulse current, small volume and high efficiency. 4. Can generate high temperature and high frequency arc, can easily ignite combustible material. 5. The peripheral circuit is simple (just plug in the switch, install the battery), the discharge rate is rapid.
