600W 25A DC DC Step Down Buck Module

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.
