XIITIA 2pcs DC 400W 15A Step-up Boost Converter Constant Current Power Supply LED Driver DC8.5V-50V to DC10V-60V Voltage Charger Step Up Module for Electric Equipment

Specifications: Type: Non-isolated boost module Input Voltage: DC8.5V to 50V Output Voltage: DC10V to 60V (continuously adjustable, default 19V) Max. Input Current: 15A (please enhance heat dissipation if more than 8A) Max. Output Current: 12A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 7A) Quiescent Current: 10mA(will increase when convert 12V to 20V) Constant Current Range: 0.2A to 12A Output Power = Input Voltage*Current Operating Temperature: -40 to 85(if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Max. Conversion Efficiency: 96% (Efficiency is related to input/output voltage, current and voltage difference) Over Current Protection: Yes (if input current is more than 15A, it will automatic reduce output voltage) Reverse Input Protection: No Size: 67 x 48 x 28mm / 2.63 x 1.89 x 1.1" Output Voltage/Current Adjustment: Adjust "CV-ADJ" potentiometer clockwise to reduce voltage, counterclockwise to increase voltage. Adjust "CC-ADJ" potentiometer counterclockwise about 30 circles to minimize the output current before connecting to load(clockwise to increase current, counterclockwise to reduce current). Then adjust "CC-ADJ" clockwise to the current value you need. If you use the module for battery charging, connect to output after battery is fully discharged. Because if the more energy is left in battery, the less charging current will be.
