DC12V DC high voltage pulse generator module ignition coil capacity arc distance 50mm. Input voltage: DC 6V-12V, input current: 0.5A-1A (voltage dependent) arc distance: 30mm-50mm bipolar high voltage discharge distance: 2cm -5cmThis module is a science of small production with high voltage transformer / Booster manufacture module. 12V input, good performance, , arc suppression, shocking sound and easy operation. This module is a finished module of high-voltage transformer/booster produced in small batches. According to DC6V-12V input voltage, it can receive tens of thousands of volts of direct current. The output high voltage can be used for high school scientific experiments, electronic equipment, negative ion generators, and high-voltage sources when used in small scientific series. The module is made of coil principle and outputs high-voltage pulse current with small size and high efficiency.
