Features 1、It can be used as high voltage source for high school science experiment, electronic instrument, negative ion generator and little science. 2、After the input of dc 3.0V-4.8V voltage, a dc high voltage of about 10,000V (about 1-2 cm of arc) can be obtained at the output end. 3、According to the coil principle, the module outputs high voltage pulse current, small volume and high efficiency. 4、It can generate high temperature and high frequency arc, can easily ignite combustible. 5、The peripheral circuit is simple (simply connect the switch, Install the battery), the discharge intensity is violent. Specification Features: 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. Specification: Input current: 1-3A Output current: ≤0.5A Work continuously time: within 10 seconds Shape: T shape, L shape, square shape, round shape(Optional) Weight: Approx.32g~37g/1.1oz~1.3oz Wiring method: Input end: red+, green- Output end: 2 pcs same colors wire Package list: 1 x Pulse Generator Note: 3.The power is large, and it is not suitable for internal heat dissipation, so it cannot work for a long time 4.About the input power: 3.7-v lithium battery can be used in series, such as 18650 battery or Nickel-cadmium/Ni-mh battery , or 4V lead Acid batteries 5.Please strictly follow the use method and precautions to operate the module, otherwise it is easy to damage the module!
