Specifications: Product name: Small power module Circuit board size:about 2x4.3cm/0.79x1.69in Overall size: about 2x6x2.5cm/0.79x0.98in Power: 50W Supply voltages: 9V Extreme voltages: 12V (note that this is the extreme voltages, which is easy to break!!) Input current: 5A~8A Output voltages: 15KV~20KV Output current: 5mA~15mA Note: If the module is heated, it means that it will take a long time to use, and it will need to be powered off and heat dissipated, or the heat sink can be increased to last longer! Package Includes: 1 PC high voltages boosting circuit board module note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution.
