Specifications:

Input Voltage: 6V to 40V DC(10V to 40V is suggested)
Output Voltage: 1.2V to 36V DC
Output Current: 20A(max.), 15A(suggested)
Efficiency: 95%(24V to 12V, 20A)
Output Ripple: ≤50mV
Wiring Method: Terminal
Short Circuit Protection: Self-recovery(cannot short circuit for long time)
Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06″
VO+: Output positive
VO-: Output negative
+IN: Input positive
-IN: Input negative
CV: Output voltage adjustment
CC: Output current adjustment
EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
When input and output is common grounded, no-load CV output constant voltage, CC output constant current
