Input voltage: two input voltage ranges selectable (jumper selectable through the back of the PCB) 1, 8~16V input (for three strings and 12V lithium storage battery applications) 2, 10~32V input (for wide input voltage range applications) Input Current: 16A (MAX) Please enhance heat dissipation than 8A Quiescent Current: 15mA (12V-liter 20V, the output voltage is higher too static current will increase) Output voltage: 9~46V continuously adjustable Output Current: 8A MAX over 4A Please enhance heat dissipation (with input, output pressure related to the pressure the greater the output current is smaller) Output power: natural cooling 90W, 150W enhance heat dissipation Working temperature: -40 to +85 degrees (ambient temperature is too high, please enhance heat dissipation) Operating Frequency: 150KHz Conversion efficiency: up to 95% (efficiency and input and output voltage, current, pressure related) Short-circuit protection: Yes (enter 15A fuse) Input Reverse Polarity Protection: No, (if necessary, please enter the string into the diode) Installation: four 3mm screws Wiring: free welding output terminals with shell welding output. (V-IN is input, V-OUT is the output)
