ITEM NAME:DC-DC Boost Converter 8~32V to 45~390V Voltage ZVS Step-up Module Single Output Descriptio n Description: Conversion efficiency: up to 88% (efficiency and input and output voltage, current, pressure-related) Short circuit protection: Yes. Over current protection: Yes. (Input current exceeds 4.5A, reducing the output voltage) Over voltage protection: Yes. (Output voltage exceeds 410V, lowering the output voltage) Input reverse polarity protection: Yes (non-self-healing, reverse burning fuse, try not reversed.) Applications: 1.Pressure test power. 2.Hunting,eradication of mice. 3.Capacitor charging,electromagnetic guns power supply. 4.The power supply for your electronic device, according to your system can set the output voltage value Specifications: High Voltage Boost Module Module Properties: Non-Isolated Step-Up Module Input Voltage: 8~32V Input(The Default Is 10~32V Input.) Input Current: 5A (Max) Quiescent Current: 15mA (12V Liter 50V, The Output Voltage, The Higher The Current Will Increase Too Quiet) Output Voltage: +45~390V Continuously Adjustable (Default Output  ±50V) Output Current: 0.2A Max(With Input, Output Pressure Related,The Higher The Output Voltage, Output Current Is Smaller) Output Power: 40W (Peak 70W) Working Temperature: -40 ~ + 85 Degrees (Ambient Temperature Is Too High, Please Enhance Heat Dissipation) Operating Frequency: 75 KHz Installation: Four 3 mm Screws Wiring: Free Welding Output Terminals Size(L*W*H):60 X 50 X 20 mm Special attention!!! The output of this module is high pressure, which will endanger the lives of people and animals. Please pay attention to safety precautions during the use process. Package Included: 1 * DC-DC Boost Converter Note: 1.Due to the manual measurement and different measurement methods, the actual size could be slightly different. 2.Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the website's photo and the actual item could be sligh.1 DC-DC Boost Converter. Over current protection: Yes. Module Properties: Non-Isolated Step-Up Module. Short circuit protection: Yes. We'd like to settle any problem in a friendly manner. Input Current: 5A (Max).
