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 3.7V-7.4V, output voltage is about DC400-800KV. Specification: Item Type: High voltage generator Model: HX-CDY Volume: Length: Approx. 135mm / 5.3in Diameter: Approx. 24mm / 0.9in Voltage Input: DC3.7-7.4V Output: DC400-800KV Current Input: 4A Output: 0.5A Line Length: Input End: Approx. 12cm / 4.7in Output End: Approx. 9cm / 3.5in Structure: Split shell Two 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 ( 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 - / -hydrogen battery pack. Package List: 1 x High Voltage Module Note: 1. The high-voltage module should avoid being energized when the high-voltage is unloaded. Before energizing, the appropriate distance of the high-voltage line end must be adjusted. The arcing distance of the high-voltage line is proportional to the battery voltage and capacity used. 2. When testing the arc distance, the experiment should be from short to . It is strictly forbidden to exceed the maximum arc distance when energized. Because the high-voltage energy cannot be released, the module is easily damaged. 3. Power of the module is large, and the internal is not suitable for heat dissipation, so it is not allowed to work for a time. 4. Method to judge whether the battery capacity can drive the maximum output power is to measure the battery voltage when the arc is drawn. If it is around 6V, it can output the maximum power. 5. The two small-capacity lithium batteries are connected in series at 7.2V. The measured voltage has dropped to about 4V in the state of arc drawing. The smaller the capacity, the lower the voltage. Therefore, it is recommended to use lithium batteries above 2000MA, and it is best to match batteries above 4000MA if possible.
