Features The product can be able to power your electronic equipment and set the output voltage value according to your system The product has high conversion efficiency which can be up to 88% Fine workmanship and stable performance, with overcurrent protection and overvoltage protection function Adopted of high quality electronic components, and accuracy process, ensure for the durability Can be applied to capacitor charging and electromagnetic gun power supply Specification:Module Name: High voltage boost module Module Nature: Non-isolated booster module Input Current: 5A(maximum) Static Working Current: 15mA (When 12V rises to 50V, the higher the output voltage, the higher the static current will increase) Output Voltage: 45-390V continuously adjustable Output Current: 0.2A, maximum(related to input and output voltage difference, the higher the output voltage, the smaller the output current) Output Power: 40W (peak 70W) Working Temperature: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high) Working Frequency: 75KHz Conversion Efficiency: Up to 88% (efficiency is related to input, output voltage, current, pressure drop) Short-Circuit Protection: Yes (input 10A fuse, please do not short-circuit the arc directly at the output end! Direct short-circuit and arc may damage the rectifier device, if you want to short-circuit and arc, please series power resistance current limiting) Overcurrent Protection: Yes (input current exceeds 4.5A, reduce output voltage) Overvoltage Protection: Yes (output voltage exceeds 410V, reduce output voltage) Input Reverse Connection Protection: Yes (non-self-recovery type, connect reverse burn fuse, try not to reverse) Installation Method: 4 x 3mm screws Wiring Method: Welding terminal free welding output (with welding output shell) Module Size: Approx. 60 x 50 x 22mm / 2.4 x 2 x 0.9in(length x width x height) The Measured Data of the Charging Time of the Capacitor: 470uF full to 390V for 2 seconds 1000uF full to 390V for 4 seconds 2200uF full to 390V for 8 seconds 4700uF full to 390V for 18 seconds Package List:1 x DC-DC Boost Module Note:The output of this module is high voltage, which will be dangerous to humans and animals. Please pay attention to safety precautions during use Package List 1 x DC-DC Boost Module
