Pulse boost module for continuous operation with a maximum discharge distance of approximately 1.5mm. Dimensions: 41 x 26 x 20mm (L x W x H). Input voltage: 3V–4.2VDC. Input current: up to 2A. No-load current: 130mA (at 4.2V). Output voltage: up to 2000V (output decreases as battery voltage drops). Output is approximately 1500V at 3V input, 1800V at 3.7V input, and 2000V at 4.2V input. Features a voltage doubler rectifier output circuit and includes a high-voltage discharge capacitor rated at 2000V 223 (0.022µF). Note: This board contains a high-voltage capacitor that may retain charge after use. Exercise caution during handling due to high voltage. For safety, always discharge the capacitor before touching or storing. Intended uses: Educational science experiments, electronic equipment, anion generation, and small-scale electronic projects. Tip: Some users may attempt to measure the output voltage. Standard multimeters typically do not have a range suitable for such high voltages. Using a 1000V range is inaccurate and may damage the meter. To safely measure output, use a resistive voltage divider method. Connect 2–3 pieces of 3MΩ resistors in series across the output, then measure the voltage across one resistor with a digital multimeter. Multiply the reading by 2 for two resistors or by 3 for three resistors to estimate total voltage. Package includes: 1 x Module
