About this item 400W DC-DC step-up boost converter module working Range: DC 8.5V to 50V input voltage, 10V to 60V continuously adjustable output voltage, 15A maximum input current, 12A maximum output current. Boost voltage converter input current is 15A (MAX) exceeds 8A. Please strengthen the heat dissipation. The quiescent working current is 10mA (12V liters 20V, the higher the output voltage, the static current will increase). The output current is 12A MAX More than 7A, please strengthen the heat. Boost converter module easy to Connect and Disconnect: Input and output are designed with screw terminals, you can connect or disconnect the wire conveniently. Boost converter module is an excellent 400 W DC to DC power module for electrical equipment, digital products, laptops and more, designed with two heat sinks for better dissipation performance; the maximum conversion efficiency can reach 96%. Please don't adjust the current by short circuit. The circuit structure of the boost module
