High voltage type: pulse DC type Output voltage: 400KV (please pay attention to safety when using) Module use note: 1, high voltage module should avoid the use of high voltage no-load, power must be adjusted before the high voltage line end of the right distance, high voltage wire drawing distance and the use of battery voltage and capacity is proportional to. 2, the test arc distance from short to long experiment, when the power is prohibited beyond the arc distance, due to the high pressure energy can not be released, very easy to damage the module. 3, the power of the module, the internal heat is not heat, so not a long time to work. Material:plastic colour:Black Package Contents: 8 x Boost high voltage generator Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
