This high-voltage generator module is based on the principle of the coil.This small, highly efficient module can trigger a high voltage pulse output with a simple supply for external circuits.Perfect for students to study electrical experiment, conduct scientific experiment etc.The of the module is and the heat dissipation inside is weak. Please allow the module to work intermittently, uninterrupted work no longer than 1 minute. Incorrect voltage and long operating times can easily damage the module.Test arc removal from short to long during the experiment. DO NOT exceed the maximum arc distance. Otherwise, the high-voltage energy cannot be released and the module can easily be damaged.Product Name: High Frequency Ignition PackageProduct model: -105Size: about 64x24mmShell structure: one half cylinderWorking voltage: 37-6vWorking current: 2AOutput current: 5MAOutput voltage: 400KV: 20WOutput line length: 11cmInput line length: 10cmContinuous working time: less than or equal to 10SArc length: 1-15cmcolour: blackMaterial: ABSPackage Contents:1 x high voltage pulse generatorOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
