800-1000KV Ultra-High Voltage Pulse Generator DC Super Arc Module 3-6V High Voltage Inverter Module
 

 
Description:
The module is divided into input end and output end, the red-green line is the input end, the red positive green is negative, the output end is two high-voltage lines of the same color, the input end connects the battery and can produce the high voltage arc.
Please operate the module in strict accordance with the method of use and precautions, otherwise it is easy to damage the module!
About the input power: You can use a single 3.7V lithium battery or two series, such as 18650 battery, idle mobile phone battery (remove the protection board, the recommended capacity is above 2000mAh) or NiCd/NiMH battery pack, 4V or 6V lead Acid battery, etc. (6V battery can achieve the best effect)
 
Note
1.The high-voltage module should be protected from power-on during high-voltage no-load operation. Before the power is applied, the proper distance of the high-voltage line must be adjusted. The arc distance of the high-voltage line is directly proportional to the battery voltage and capacity used.
2.When testing the distance between arcs, the experiment must be conducted from short to long. It is forbidden to exceed the longest arcing distance when power is applied. Since high-voltage energy cannot be released, the module can be easily damaged.
3.the module\'s power, internal heat should not be, it can not work long hours, generally within 10 seconds is no problem.
4.The method of determining whether the battery capacity can drive the maximum output power is to measure the battery voltage when the arc is pulled. If it is around 6V, it can output maximum power.
5.small-capacity lithium-ion two series connected to 7.2V, in the arc state measurement voltage has dropped to about 4V, the smaller the capacity, the lower the voltage pull. Therefore, it is recommended to use more than 2000MA lithium battery, the best condition with more than 4000MA battery.
 
Package Included:
1 Pcs 800-1000KV Ultra-High Voltage Pulse Generator DC Super Arc Module
