DC3.7V-6V High Voltage Pulse Generator Output 50KV Super Arc Ignition Coil Module 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 3.7V to 6V 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: 64*22*24mm/2.52*0.86*0.94" Input Voltage: 3.7V-6V DC Input Current: 0.5A-1A Input Cable Length: Approx. 11cm/4.33" High Voltage Type: Pulse DC Output Voltage: About 50KV Output Current: 0.5A-1A Output Cable Length: Approx. 10cm/3.93" Arc Discharge Distance: 0.5cm/0.19 to 1.5cm/0.59"  Power Supply: 3.7V Li-ion battery, Ni-Cd/Ni-mh battery pack, 4V or 6V lead-acid battery(6V is better) 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, With less capacity battery, the output voltage is lower. Li-ion battery of 2000mA, 4000mA or more is suggested. Package Includes: 1 x High Voltage Generator
