DC12V DC high voltage pulse generator module with ignition coil and arc distance of up to 50mm. Input voltage: DC 6V-12V. Input current: 0.5A-1A (voltage dependent). Arc distance: 30mm-50mm. Bipolar high voltage discharge distance: 2cm-5cm. This module is a small-scale scientific production unit utilizing a high-voltage transformer/booster design. 12V input provides stable performance with arc suppression, audible discharge, and easy operation. It is a fully assembled high-voltage transformer/booster module manufactured in limited quantities. With a DC6V-12V input, it generates high-voltage output suitable for educational science experiments, electronic devices, negative ion generators, and small-scale high-voltage power applications. Based on coil transformer principles, it delivers high-voltage pulse current with compact size and high efficiency.
