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-4.8V voltage, a dc high voltage of about 10,000V (about 1-2 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. Specification: Input voltage: 3.0 -4.8V (1* 3.7v lithium battery ) Input current: 1-3A Output voltage: about 400KV (please pay attention to safety when using Output current: ≤0.5A Discharge distance between high voltage poles: 0.5-1.5cm (beyond limits) Work continuously time: within 10 seconds Attention! The input voltage will affect the output voltage and arc distance. Shape: T shape, L shape, square shape, round shape(Optional) Weight: Approx.32g~37g/1.1oz~1.3oz Wiring method: Input end: red+, yellow- Output end: 2 pcs same colors wire Package list: 1 x Pulse Generator Note: 1.Avoid high-voltage no-load power supply. (it is necessary to adjust the appropriate distance of the high-voltage cable end before energizing. The distance of the high-voltage cable to pull the arc is directly proportional to the voltage and capacity of the battery used. When measuring arc distance, the test shall be conducted from short to long. 2.Power is strictly forbidden when exceeding the maximum arc distance. As the high voltage energy cannot be released, modules are easily damaged. 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! 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 tesla 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.
