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
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
Working Tempreture: -10°C-75°C


With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current
The efficiency can be up to 96%, measured at 20A, converting 24V to 12V
Designed with 75V/80A large current dual MOS tube
The buck module has 2 heat sink that could enhance heat dissipation
Wiring is convenient with these large current 30A screw terminals
Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output
Stable and reliable
Fine workmanship and durable

Package included:

1 x 300W 20A adjustable step-down converter module
