High-frequency and high-voltage AC output can be used to power the voltage doubler rectifier board, and can also be used to charge the capacitor after rectification. It must be powered within the nominal voltage range to work properly! If the voltage is too low, the module stop working due to undervoltage. Reverse connection and overvoltage are strictly prohibited, otherwise the module be and even cause the capacitor to explode! Note: This product is a semi-finished product without a shell, and the photo is the actual product. Continuous working time: 24 hours No-load characteristics: sustainable no-load Input voltage: 12V-24V Input current:Less than 2A Maximum power:Less than 48W (varies with input voltage) Output voltage: 820V-2000v (varies with input voltage) AC frequency: 23KHz Arc starting distance: 1-2mm Maximum arc distance: 20mm Full power arc temperature: 1600℃(can melt thin iron wire) Arc characteristics: orange, high temperature (The module former part has been encapsulated and does not need to be re-encapsulated. It is recommended to install a fan for long-term work) Different factory batches may have slight differences in appearance, which not affect the use.
