Specifications: Input Voltage: DC 3 V to 6 V Input Current: 2 A - 5 A High Pressure Type: The type of pulse current Output Voltage: 400000V(please pay attention to safety) High Pressure Discharge Distance Between: Approx. 10 ~ 20mm / 0.4 ~ 0.8in The Output High Voltage Wire Length: Approx. 100mm / 3.9in Input Power Cord Length: Approx. 100mm / 3.9in (the red line is positive) Wiring: Red and green power connection red line:"+" green line "-" output: the other side ,same color cable Size: Approx. 24 x 22 x 63mm / 0.9 x 0.9 x 2.5in 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: 1 X High Voltage Transformer .
