Welcome to our shop! Features: - The module can output high voltage pulse current, small size, and high efficiency. - This module is the finished module of the transformer for small scientific production. - The input voltage is DC 6V to 12V, and it will output 1000kV high voltage. - It can be used for a negative-ion generator, electronic instrument, and science experiment. - The peripheral circuit is simple, simply connect the switch and battery, and the discharge intensity is great. Specifications: - Input Voltage: 6V~12V DC - Input Current: 2A~5A (related to voltage) - Output Voltage: About 500KV~1000KV - Input Cable Length: About 100mm (red is positive) - Output Cable Length: About 100mm - Arc Discharge Distance: 10mm~20mm Instruction: 1. You can use two 3.7V lithium batteries in series, such as 18650 batteries, idle mobile phone batteries (remove the protection board, the recommended capacity is more than 2000mAh) or nickel-cadmium/nickel-metal hydride battery packs, 4V or 6V batteries. 2. This module is a finished module of a high-voltage inverter transformer/booster for scientific small production. After inputting DC6-12V voltage at the input end, a DC high voltage of about 500,000 volts (about 1-2 cm arc) can be obtained at the output end. It can be used as a high-voltage source for general experiments, electronic instruments, negative ion generators, and small scientific productions in Chinese subjects. 3. The way to judge whether the battery capacity can drive the maximum output power is to measure the battery voltage during arcing. The maximum power can be output if it is around 6V. Two small-capacity lithium batteries are connected in series to 7.2V, and the measured voltage has dropped to about 4V in the arcing state. The smaller the capacity, the lower the voltage will be. Therefore, it is recommended to use a lithium battery above 2000mA, and it is best to match a battery above 4000mA if possible. Note: 1. Output ends of the cable should be adjusted properly before power on, and the arc distance depends on battery voltage and capacity. 2. The arc distance should be from short to long, do not produce the longest arc at first, or the module might be damaged easily. 3. The module has high power and inner heat is not easily dissipated, so it cannot work continuously for a long time (<10 seconds each time). 4. The way to judge if a battery capacity is enough to output maximum power is to measure the battery voltage when producing an arc. If the measured voltage is about 6V, then it can output maximum power. The recommended battery capacity is above 2000mA, or above 4000mA if possible.
