Specifications:
Color: Silver
Material: Metal
Size: Approx. 60 x 52 x 27mm / 2.36 x 2.05 x 1.06''
Input Voltage: DC 6-40V (10V to 40V is suggested)
Output Voltage: DC 1.2-36V
Output Current: 20A(max.), 15A (suggested)
Efficiency: 97% (24V to 12V, 20A)
Output Ripple: ≤50mV
Wiring Method: Terminal
Short Circuit Protection: Self-recovery (cannot short circuit for a long time)
VO+: Output positive
VO-: Output negative
+IN: Input positive
-IN: Input negative
