Features:High temperature arc igniter, with 3-6v high power, instant ignite cigarette & paper, can work for 20 seconds continuously, and high frequency, good quality, easy to use.It can be used ashigh voltage source for high school science experiment, electronic instrument, negative ion generator and little science.It can generate high temperature and high frequency arc, can easily ignite combustible.According to the tesla coil principle, the module outputs high voltage pulse current, small volume and high efficiency.The peripheral circuit is simple (simply connect the switch, Install the battery), the discharge intensity is violent.Specifications:Size: 55*24*22mm/2.17*0.94*0.87inchInput voltage: 3V-6VInput Current: 0.5A-2A(depending on the input voltage)Input line length: about 10cm/3.94inchHigh Voltage type: DC typeOutput voltage: about 700KV (please pay attention to safety when used)Output current: 0.5AOutput line length: about 10cm/3.94inchHigh voltage poles ignition distance: 1.5cm(1.5cm is maximum distance, 1cm is better)Note:1.Input the power of 3-6v, output two levels of terminal can produce 1.5cm length purple high temperature arc, instant ignition paper, single high voltage line can also discharge of any metal body, working without a crack sound.2.On the input power: 3.7-v lithium battery can be used in series, such as 18650 battery, idle cell phone battery (to remove the protection board, recommended capacity above 2000mAh) or Nickel-cadmium/Nimh battery pack,4V or 12V lead Acid batteries(12V battery works best) Module Usage Precautions:1. Avoid power on when No load. You must adjust the appropriate distance for high-voltage terminal before power on, high-voltage line arc distance is proportionalto the battery voltage and capacity. 2. The test arc distance from the short to long experimental, It is prohibited exceed the maximum arcing distance(<1.5cm,1cm is OK). Otherwise, energy can not be released due to high voltage, easily damaged modules.3. The module power, the internal is not easy for heat dissipation, so it can not work for a long time.4.To determine whether the battery capacity can drive the maximum output power is the way to measure the battery voltage when in the arc state.5. Small capacity series lithium battery is 7.2 V, voltage will drop to about 4V when arcing, the smaller the capacity, the lower the voltage will become. It is recommended to use above 2000MA lithium, it is better to choose above4000MA battery.Package Included:1 x High Voltage Pulse GeneratorNote:1.The power time is not above 20 seconds each time. Since the output power is strong, itmust be driven by rechargeable battery or storage battery. Improper voltage and long work will easily damage the high voltage module. Be careful when testing and using!2. Ignite distance keep within 1cm, please
