SMAKN&reg; 1200W 20A DC Converter Boost Step-up Power Supply Module IN 8-60V OUT 12-80V Input voltage: 8-60V. Input Current: 20A. Quiescent current: 15mA (12V liter 20V, the output voltage, the higher the current will increase too quiet). Output voltage: 12-80V continuously adjustable. Output Current: 20A MAX than 18A, please enhance heat dissipation (input, output pressure related, the greater the pressure the smaller the output current).
