SMAKN DC-DC DC 8.5-48V Step-UP 55-60V 300W DC Convert Constant Voltage Constant Current led Driver Module Name: 300W boost constant current module. Module Properties: non-isolated step-up module (BOOST). Input voltage: DC8.5V-48V. Input Current: 16A (MAX) more than 12A, please enhance heat dissipation. Quiescent current: 10mA (when 12V to 20V, output voltage, the higher the current will increase too quiet).
