High-frequency and high-voltage AC output can be used to power the voltage doubler rectifier board and to charge capacitors after rectification. Must be powered within the nominal voltage range for proper operation. Low input voltage may cause the module to stop working due to undervoltage. Reverse polarity connection and overvoltage are strictly prohibited, as they may damage the module or cause capacitor failure. This product is a semi-finished module without an enclosure; the image shows the actual item. Continuous working time: 24 hours. No-load capability: supports sustained no-load operation. 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: approximately 1600°C (capable of melting thin iron wire). Arc characteristics: orange-colored, high-temperature arc. The primary side of the module is encapsulated and does not require additional encapsulation. Use with a cooling fan is recommended for extended operation. Slight variations in appearance between production batches may occur but do not affect performance. Color: Green. Material: Plastic. Package includes: 1 x High Voltage Module Voltage Multiplier Driver. No other items included. Note: Lighting and display settings may cause slight color differences between the image and the actual item. Measurement tolerance: ±1–3cm.
