The module can generate high voltage pulse current, small size and high efficiency. This module is a ready-made module of the transformer do small scientific production. The input voltage ranges from 6V do 12V DC and will generate a high voltage of 1000kV. It can be used do negative ion generator, electronic instrument and scientific experiment. The peripheral circuit is simple, just connect the switch and battery, and the discharge intensity is large. Input voltage: 6 V 12V DC Input current: 2A 5A (relative to do voltage) Output voltage:about 500 kV 1000 kV Input cable length: about 100 mm (red is positive) Output cable length:approximately 100 mm Arc discharge distance:10 mm 20 mm Package includes: 1 x high voltage generator 2, The arc distance should be from short do long, do not produce the longest arc first, otherwise the module can easily be damaged. 3, The ma high power, and the internal heat is not easily dissipated, so it can not work continuously for a long time (every time Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
