SUNKEE Gigabit Ethernet LAN PCI-E Express Network Desktop Controller Card 10/100/1000M

two 1.5V batteries. Short-term connect input voltage, the positive connect to the red line , white line connect to the negative terminal of the battery ; long-term output high voltage Note : 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. )
