Product parameters:
Input voltage :12-75V
Output voltage range :2.5-60V(step-down conditions must be met, and IN input multiplied by 0.8)
Output constant current :1-25A
Maximum output power :600W
Continuous maximum working power :500W
Continuous maximum working current :25A
Operating frequency :80KHz
Short-circuit protection: constant current protection
Output feedback: none (To charge the battery, the output should be connected to an inductive load, such as a feedback diode must be added to the motor)
Working indicator: Output voltage blue LED light

Features: Module adopts step rectification scheme, high efficiency, the highest efficiency can reach 95%, the output voltage and current can be adjusted continuously, the input voltage can reach 75V, the output voltage can reach 60V(when the input voltage is 75V), the maximum current is 25A.
Voltage and current adjustment method :(Use multimeter, flat-head screwdriver)
Voltage regulation: Rotate the "VIADJ" blue potentiometer on the power supply board according to the required voltage, turn the voltage up clockwise and turn it down anticlockwise
Output current adjustment: multimeter or ammeter to 20A or 10A current gear, the power supply voltage to 5v, constant current potentiometer "IADJ" counterclockwise about 10 turns, the current to the minimum short-circuit output with the multimeter, and then clockwise adjust the "IADJ" potentiometer to the current to the required current value, Note: When the constant current potentiometer "IADJ" turns 10 times counterclockwise, the power supply may have no output voltage, because the current is adjusted to 0A. Don't worry about it. Turn up the current clockwise and you'll get an output.
The current detection of the module is low-end. Do not short-circuit the input negative electrode and the output negative electrode directly with a wire. This will short-circuit the negative power supply and cause damage to the power supply and the electrical equipment requiring constant current.
If the module is a step-down power supply, it can only be step-down. The input voltage must be higher than the output voltage.

Note:
1. Input is not protected by reverse connection. Do not reverse connection
2. If the battery is charged, when the output is connected to the inductive load, the output should add the anti-backfilling diode
3. Long time high power, high current when the heat dissipation.
