1. Wide compatibility: This is an excellent 400W DCDC boost converter, suitable for electrical devices, digital stepup converters, laptops, etc. 400W DCDC highpower boost converters can be used as drivers for highperformance LED lights or controllers for solar panels. Input and outputs feature screw terminals for easy connection and disconnection of wires. 2. High efficiency: The maximum conversion efficiency of the 15A stepup boost converter is 96%, the maximum input voltage is DC8.5V to 50V, and the output voltage is DC10V to 60V (continuously adjustable, standard 19V). The maximum output current is 12A. If the current exceeds 7A, please increase the heat dissipation of the stepup booster module. 3. Safety protection: 400W DCDC constant current stepup converter of the DC converter to avoid accidents caused by excessive temperature. If the input current is more than 15A, the output voltage is automatically reduced to maximize for you and the device. The voltage regulator adjustable for better heat dissipation are installed two radiators. 4. Highquality material: The stepup power supply module is made of plastic with good wear resistance, good insulation and low thermal conductivity.
