Features: It can be used as high voltage source for high school science experiment, electronic instrument, negative ion generator and little science. After the input of dc 3.0V-6V voltage, a dc high voltage of about DC200KV(about 1.5 cm of arc) can be obtained at the output end. According to the tesla coil principle, the module outputs high voltage pulse current, small volume and high efficiency. It can generate high temperature and high frequency arc, can easily ignite combustible. The peripheral circuit is simple (simply connect the switch, Install the battery), the discharge intensity is violent. Used for high voltage production, electronic DIY, product development, high voltage electronic security, etcSpecification:Product name: high voltage generatorModel: 800 Voltage: input dc3.7-6v, output DC200KVCurrent: input 4A, output 0.5ALine length: input about 7 cm, output about 10 cmStructure: integral shell typeBipolar discharge distance: about 1.5 cm (beyond easy damage)Size: 40x40x18mm or 1.6x1.6x0.7inWeight: Approx.47g or 1.7ozMethod of use:The high voltage output end (monochrome thick wire) is fixed at the two poles within the specified discharge distance, and the low voltage input end (two-color fine wire) is connected with the battery by the red wire positive pole and the green wire negative pole.Package list:1 x Pulse GeneratorNote:This product does not need auxiliary circuit, and the battery can be directly used. The input end is connected to a single 3.7v lithium battery (such as 18650 battery) or nickel-cadmium or nickel-metal hydride battery pack, 4V or 6V lead-acid battery, etc. (6V battery can achieve the best effect).
