Features: 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. 2. Adopt for tesla coil principle, output high-voltage pulses, powerful discharge strength. 3. Compact size, high efficiency, stable and professional performance, dependable to use. 4. The input voltage is less than 7.2V and will output about 800KV high voltage. 5. Built to meet standard specification, strictly follow factory quality control. Specifications: High voltage type: pulse direct current split type Input voltage: less than 7.2V(no more than 7.2V) Input current: 2.4A (Different depends on input voltage) Output voltage: appro 800KV (please pay attention to safety when using!) Output current: approx. 1A High voltage bipolar discharge distance: 3cm Discharge time: appro 50s (no more than 1 minutes) Size: 14 x 2.3 cm Product usage method: 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. About input power: Can use single section 3.7V lithium battery or two series, such as 18650 battery, the idle mobile phone battery (to remove protective plate, proposed capacity above 2000mAh) or nickel cadmium / NiMH battery pack, 4V or 6V lead-acid batteries and other (to achieve the best effect of 6V battery) Module use matters needing attention: 1. High voltage module should avoid the use of high voltage no-load, power must be 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. 2. To test the arc distance from short to long experiment, when the power is strictly prohibited beyond the maximum pull arc distance, due to the high pressure energy can not be released, very easy to damage the module. 3. The power of the module is large, internal heat dissipation, it is not a long time to work. 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. 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. Note: 1.The size of the input voltage will affect the output voltage and arc distance. 2.Note that this is not a high temperature arc, not cigarette paper 3.Please use the methods and precautions to operate in strict accordance with the operating module, otherwise it is easy to damage the module. Package include: 1 x High Electric Arc Generator .
