This 70W high-frequency AC boost coil is designed to convert a DC 9-12V input into a powerful AC 20KV high voltage output. Suitable for various DIY high-voltage experiments, ignition systems, and scientific projects that require strong and stable discharge. This module has been optimized for 12V low heat operation, effectively reducing heat generation during use, improving safety, and extending service life. Under appropriate cooling and operating conditions, it supports continuous arc discharge for up to 10 minutes. High frequency AC output produces concentrated and strong arcs, with excellent visual and practical effects. This makes it suitable for high-voltage display devices, ignition experiments, and other applications that require clear and stable arcs. The high-voltage ignition module provides AC output up to 20KV, providing generation and powerful ignition performance. It is very suitable for demonstration, experimentation, testing, and educational purposes that require continuous high-voltage discharge. Very suitable for electronic DIY enthusiasts, teaching demonstrations, laboratory experiments, and ignition system simulations. Not suitable as a toy; Users should have basic knowledge of high-voltage safety and appropriate insulation technology., Manufacturer: Aundhegrtt
