Check the listing for details. 2Pcs DC 3v-6v to 400kV 400000V Boost Step-up Power Module High-voltage Generator. Color: As picture shown, Condition: New. Listed at 9.59 USD. Description:input voltage: DC 3 V to 6 VInput current: 2 A - 5 AHigh pressure type: the type of pulse currentOutput voltage: 400000 v(Please pay attention to safety)High pressure discharge distance between: 10 mm - 20 mmThe output high voltage wire length: 100 mmInput power cord length: 100 mm (the red line is positive)Wiring:Red and green power connection red line:"+" green line "-"output : the other side ,same color cable Please notice:the high-voltage module should avoid the use of electricity in high voltage no-load . (Power must be adjusted to a suitable distance to the high-voltage output line , battery capacity is proportional to the distance and the use of the high-pressure arc ( not a voltage as high as possible , you must provide enough current ) . Experimental test of the arc distance from short to long , Do not exceed the maximum arc distance electricity, energy can not be released due to high pressure , can easily damage the module. )Work: intermittent , continuous work does not allow more than 1 minute and the output side does not allow shorting . Improper voltage and long working hours easily damaged module. Package included:2PCS High-voltage Generator
