Features The module can output high voltage pulse current, small size and high efficiency This module is the finished module of transformer for small scientific production The input voltage is DC 6V to 12V and will output tens of thousands DC high voltage It can be used as high voltage power source in high school science experiment, electronic instrument, anion generator The peripheral circuit is simple, simply connect the switch and battery, and the discharge intensity is great  Specifications: Size: 70*30*24mm/2.75*1.18*0.94" Input Voltage: 6V-12V DC Input Current: 0.5A-1A Input Cable Length: Approx. 26cm/10.23" High Voltage Type: Pulse DC Output Voltage: About 60KV Output Current: 0.5A-1A Output Cable Length: Approx. 48cm/18.89" Arc Discharge Distance: 1.5cm/0.59" to 2cm/0.78" Power Supply: Ni-Cd/Ni-mh battery pack, 6V or 12V Note: 1, Output ends of 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 a 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 can not work for long time. 4, The way to judge if a battery capacity is enough to output maximum power is to measure the battery voltage when producing arc. It the measured voltage is about 6V, then it can do the trick. Package Includes: 1 x High Voltage Generator Package List
