1,High voltage module can be used as a high-voltage source for students' popular science experiments, electronic instruments, negative ion generators and science small productions. 2,Power boost module is made by using the principle of boost discharge with high voltage pulse output, and the discharge strength is violent. 3,Meanwhile, high efficiency and small size module installation is simple, not require particularly complicated operations. 4,And such voltage boost module can be used in high-voltage production, electronic DIY, product development, high-voltage electronic anti-theft, etc. 5,High voltage generator's input voltage is 7V-7.4V, output voltage is about DC400-800KV. 1 x High Voltage Module Item Type: High voltage generatorModel: HX-CDYVolume:Length: Approx. 135mm / 5.3inDiameter: Approx. 24mm / 0.9inVoltage Input: DC 3.7- 7.4VOutput: DC400-800KVCurrent Input: 4AOutput: 0.5ALine Length:Input End: Approx. 12cm / 4.7inOutput End: Approx. 9cm / 3.5inStructure: Split shellTwo Poles Discharge Distance: Approx. 1 - 3cm / 0.4 - 1.2in(easy damage while outside the range)Uses: Commonly used in high-voltage production, electronic DIY, product development, high-voltage electronic anti-theft, etc.How to Use: The two poles of the high-voltage output end (monochrome thick wire) are fixed within the prescribed discharge distance, and the low-voltage input end (two-color thin wire) red wire positive electrode and green wire negative electrode are connected to the battery to produce high voltage arc work.Input Requirements: This product does not require an auxiliary circuit, and can be used directly by connecting the battery. The input terminal is connected to a single 3.7V lithium battery (such as 18650 battery) or nickel-cadmium/nickel-hydrogen battery pack. 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.
