Input reverse protection: Yes (MOS transistor reverse connection)
Output anti backflow: None (charging the battery, connecting the output to an inductive load, such as adding anti backflow diodes when connecting to the motor)

Precautions:

1. If the input voltage exceeds 36V, first turn the ON/OFF switch to OFF, connect the wire, and then turn the switch to ON (to prevent ignition during wiring)
2. This power supply is a step-down power supply, and the output voltage can only be lower than the input voltage
3. Under natural heat dissipation, the power should not exceed 400W and the current should not exceed 15A. There is a power limit. If the output voltage is high and the input output voltage difference is large, please reduce the current and use it
4. If the current exceeds 15A and the power exceeds 400W, please add a fan for heat dissipation
Voltage and current adjustment method: (using a tool multimeter and a flat screwdriver)
Voltage regulation: turn the blue Potentiometer on the power panel according to the voltage you need, and turn the voltage up clockwise and down counterclockwise;
Output current regulation: turn the multimeter or Ammeter to 20A or 10A current gear, adjust the power supply voltage to 5V, turn the constant current Potentiometer counterclockwise for about 10 turns, adjust the current to the minimum, use the multimeter for short circuit output, and then adjust the Potentiometer clockwise to adjust the current to the required current value;
The current detection of the module is a low-end detection. Please do not directly short circuit the input negative pole and output negative pole with wires, as the short circuit negative pole power supply may not have constant current, resulting in damage to the power supply and electrical equipment that requires constant current.
The module is a step-down power supply that can only reduce voltage but cannot increase it. The input voltage must be higher than the output voltage.

300W20A Step Down Module:

Feature:

In a wide input voltage range of 6V to 40V, the buck converter can accurately adjust the output voltage and current.
The efficiency can reach 96%, and the measurement is 20A, which is converted into 24V to 12V.
Using 75V/80A high current dual MOS tube design.
Input and output use high-frequency low-resistance electrolytic capacitors, low ripple and stable output.
These high-current 30A screw terminals are convenient for wiring.
The step-down module has 2 heat sinks to enhance heat dissipation.
When there is a big difference between the input and output voltages, please reduce the power supply and current.

Specifications:

Input voltage: 6V to 40V DC (10V to 40V is recommended)
Output voltage: 1.2V to 36V DC
Output current: 20A (maximum), 15A (recommended)
Efficiency: 95% (24V~12V, 20A)
Output ripple: ≤50mV
Connection method: terminal
Short circuit protection: self-recovery (can't short circuit for a long time)
Size: 60*53*27mm / 2.36*2.08*1.06"

VO +: positive output
VO-: output negative
+ IN: input positive
-IN: Enter a negative number
CV: output voltage regulation
CC: Output current adjustment
EN: enable, turn off the output at low level; pause, valid at high voltage level

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

Output current adjustment method:

1. CV potentiometer adjustment, depending on your load requirements, the output voltage is set to the voltage value you need.
2. CC potentiometer counterclockwise located about 30 laps, (ie, the output current is set to a minimum), connected to the LED, potentiometer CC tune to the desired current. After charging for battery, the battery fully discharged, and then to output, adjust to your desired current CC, (be sure to use for charging batteries completely discharged before being allowed to transfer, because the battery power is left in the more, the charging current is smaller.) Please do not use the short-circuit current way of transfer, the circuit structure of the module can not short-circuit the way transfer
