Product Description 15KV High Frequency High Voltage Transformer Product Details Size: 29 x 24 x 18 mm (Length x Width x Height, measured at the most prominent part) Applications Ideal for use in science experiments, electronic instruments, negative ion generators, and other scientific productions. Important Notes The transformer features a high-voltage winding in the inner layer, encapsulated in epoxy resin, while the low-voltage winding is in the outer layer. It is crucial not to confuse these winding methods. This circuit produces a stable high-frequency arc during operation. The temperature is extremely high, capable of igniting combustibles easily. If the secondary high voltage output is not rectified, it creates a high-frequency, high-voltage output with a light purple arc, capable of igniting paper and fine iron wire. Connecting the output to several voltage-compression circuits will generate DC high voltage, suitable for negative ion generators. The transformer is compatible with a 12V voltage but requires adjusting the base feedback resistance between 150Ω and 1.5KΩ. Adjust from large to small to prevent damage. Designed for a maximum output of 15KV, ensure that output does not exceed this limit to prevent damage. For long-term reliability, seal it completely with insulating wax or epoxy resin. Avoid operation without load. Package Includes 1 x 15KV High Frequency High Voltage Transformer
