Type: Non-isolated boost module
Input Voltage: DC8.5V to 50V
(Must not be less that 1V lower than selected output Voltage)
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 (Note: The higher the input to output voltage difference is then
the lower the lower the output current can be drawn.
Additional heat sinking is required if the output 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)
Operating 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 above 15A, it will automatically reduce output voltage)
Reverse Input Protection: None
