DC 3.7V to 1800V Step Up Module Arc Pulse DC Motor with High Voltage Capacitor 3.7V 2A Booster Power Supply Module 3-4.2V Input Specification: Input voltage: 3-4.2V Input current: up to about 2A No-load current: 130MA (4.2V voltage) Output voltage: 2000V (battery voltage is low, output voltage will also become lower) Precautions： When the 3V voltage is input, the output is about 1500V, the 3.7V input is about 1800V, and the 4.2V input is about 2000V. This is a high-voltage, low-current, low-power boost module. If you want to increase the instantaneous discharge current, you can output a large-capacity, high-voltage capacitor in parallel (recommended to use 4 CB65 capacitors for air conditioners and 450V for series connection. Size you choose according to your needs) Output circuit is voltage doubler rectifier With high voltage discharge capacitor, 2000V 223 The board has a high-voltage capacitor, which may leave excess capacitance after use High pressure danger, use need to pay attention to safety Note: 1.Due to the light and screen difference, the item's color may be slightly different from the pictures. 2.Please allow 1-3cm differences due to manual measurement. Package includes: 1x Booster Power Supply Module
