Features:_x000D_ 1. The high-voltage module/generator made by the circuit composed of components, can be used as a high-voltage source for school scientific experiments, electronic devices, negative-ion generator and science small productions._x000D_ _x000D_ 2. Adopt for tesla coil principle, output high-voltage pulses, powerful discharge strength._x000D_ 3. Compact size, high efficiency, stable and professional performance, dependable to use._x000D_ 4. The input voltage is less than 7.2V and will output about 800KV high voltage._x000D_ 5. Built to meet standard specification, strictly follow factory quality control._x000D_ _x000D_ _x000D_ Specifications: _x000D_ High voltage type: pulse direct current split type _x000D_ Input voltage: less than 7.2V(no more than 7.2V) _x000D_ Input current: 2.4A (Different depends on input voltage) _x000D_ Output voltage: appro 800KV _x000D_ (please pay attention to safety when using!) _x000D_ Output current: approx. 1A _x000D_ High voltage bipolar discharge distance: 3cm _x000D_ Discharge time: appro 50s (no more than 1 minutes) _x000D_ Size: 14 x 2.3 cm _x000D_ _x000D_ _x000D_ Product usage method: _x000D_ Module input terminal and the output terminal, red and green line is Input terminal, red"-" green"+",two thick line which has same color is the high voltage output, fixed output end of the proper arc distance and input end is connected with a battery can generate high-voltage electric arc. _x000D_ _x000D_ About input power: _x000D_ Can use single section 3.7V lithium battery or two series, such as 18650 battery, the _x000D_ idle mobile phone battery (to remove protective plate, proposed capacity above _x000D_ 2000mAh) or nickel cadmium / NiMH battery pack, 4V or 6V lead-acid batteries and _x000D_ other (to achieve the best effect of 6V battery) _x000D_ _x000D_ Module use matters needing attention: _x000D_ 1. High voltage module should avoid the use of high voltage no-load, power must be _x000D_ adjusted before the appropriate high voltage line ends, high voltage wire pull arc distance and the use of the battery voltage and capacity is proportional to. _x000D_ 2. To test the arc distance from short to long experiment, when the power is strictly _x000D_ prohibited beyond the maximum pull arc distance, due to the high pressure energy _x000D_ can not be released, very easy to damage the module. _x000D_ 3. The power of the module is large, internal heat dissipation, it is not a long time to work. _x000D_ 4. To determine whether the battery capacity to drive the output of the maximum power is to measure the voltage of the battery when pulling the arc, if you can output the maximum power of about 6V. _x000D_ 5. Small capacity lithium battery two series for 7.2V, in pull arc voltage measurement has fallen to around 4V, capacity of the smaller voltage lower. It is recommended that the lithium 2000mA above, there are more than the best conditions with 4000MA battery. _x000D_ _x000D_ _x000D_ Note: _x000D_ 1.The size of the input voltage will affect the output voltage and arc distance. _x000D_ 2.Note that this is not a high temperature arc, not cigarette paper _x000D_ 3.Please use the methods and precautions to operate in strict accordance with the operating module, otherwise it is easy to damage the module. _x000D_ _x000D_ Package include: _x000D_ 1 x High Electric Arc Generator
