Description: 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) Wiring: free welding output terminals Size(L*W*H): Approx. 60 x 50 x 20 mm / 2.36x1.97x0.79inch Specification: 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 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 ( reverse burning fuse, try not reversed.) Installation: Four 3 mm screws 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. Package Includes: 1 Piece of Booster Module
