DC 300W 20A Constant Current Adjustable Step Down Converter Voltage Module

DC 300W 20A CC CV Constant Current Adjustable Step Down Converter Voltage Buck Current Source Module 
Features: 
1. With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. 
2. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. 
3. It is designed with 75V/80A large current dual MOS tube. 
4. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. 
5. Wiring is convenient with these large current 30A screw terminals. 
6. The buck module has 2 heat sink that could enhance heat dissipation. 
7. When there is a big difference between input and output voltage, please decrease power and current. 

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: approx. 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.
