SMAKN&reg; High Voltage Boost Converter 8-32V to 45V-390V 110V/220V ZVS Capacitor Charging Input voltage: two input voltage range selectable, (jumper selectable through the back of the PCB, default setting 10-32V input): 1) 8V-16V input 2) 10V-32V input Input Current: 5A (MAX) Quiescent current: 15mA (12V step up to 50V, the higher the output voltage will increase the quiescent current) Output voltage:  45-390V continuously adjustable (the default output  50V. This module has regulator function, after adjusted output voltage is stable and unchanging, not with changes in input voltage changes) Output Current: 0.2A MAX (affected by input voltage and dropout voltage,the higher the output voltage, the smaller the output current)
