• 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

• It is designed with a 75V/80A large current dual MOS tube

• Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output

• Wiring is convenient with these large current 30A screw terminals

• The buck module has 2 heat sinks that could enhance heat dissipation

• 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: 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

Output Current Adjustment Method:

• 1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.

• 2. Set the CC potentiometer counterclockwise about 30 turns (that is, set the output current to the minimum), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after the battery is fully discharged, connect it to the output, and adjust the CC to the current you need. The more, the smaller the charging current.)

Wiring Instructions:

• OUT+: output positive

• OUT-: output negative

• +IN: input positive

• -IN: Enter a negative number

• CV: Output Voltage Regulation

• CC: output current regulation

• EN: Enable, low level closes output; Pause, high voltage level active

• When the input and output are grounded, no-load CV output constant voltage, CC output constant current
