Features 1、This module is a finished module of transformer/booster for small scientific production 2、It can output high voltage arc, small size and high efficiency 3、The input voltage is DC4.8V-6V and will output 50kV-800kV high voltage 4、It can be used for high voltage experiment, teaching in high school or college 5、The peripheral circuit is simple, simply connect to switch and battery, and the discharge intensity is great Specification Features: This module is a finished module of transformer/booster for small scientific production. The peripheral circuit is simple, simply connect to switch and battery, and the discharge intensity is great. Specifications: Electric Arc Distance: <20mm Wiring: Battery positive: Red (or Yellow) wire Battery negative: Green (or White) wire Note: 2, The arc distance should be from short to long, do not produce a longest arc at first or the module might be damaged easily. 3, The module has high power and inner heat is not easily dissipated, so it can not work continuously for long time (<1 minute each time). Two output wires can NOT connect to each other. Package Includes: Package List
