Dual power parallel supply and UPS application.2. Redundant power supply application.3. Parallel connection of primary/secondary batteries.4. Drones, electronic devices, etc. are constantly powered to replace batteries.5. Anti backflow of batteries, solar energy, and power modules.6. DC electronic and power modules, electronic equipment input reverse protection.Precautions1. The negative pole of the main current circuit does not need to pass through the module, but the negative pole on the module must be connected (using a thin wire).2. It can only be used in DC, with a turn-on frequency not exceeding 150HZ, and cannot be used for AC rectification.3. Pay attention to the breakdown of the chip by surge voltage. If the working voltage is high and there are inductive loads, please increase the input and outputTVS diodes and electrolytic capacitors absorb surge voltages.4. When the working current is high and the heat generation is significant, it is necessary to strengthen heat dissipation (by increasing the number of heat sinks or air cooling).5. Multiple parallel connections can be used to increase current, or multiple parallel connections can be used to increase the number of channels.6. When applying the main/auxiliary battery in parallel, if the main battery is not equipped with an ideal diode, attention should be paid to the voltage of the auxiliary batteryCannot exceed the voltage of the main battery. If both the main and auxiliary batteries are connected to ideal diodes, there is no voltage when connected in parallelPoor requirements.7. Do not measure the internal resistance of an ideal diode using the diode and resistance settings of a multimeter, as this is an incorrect measurementMethod: The internal resistance can be calculated by the voltage drop of an ideal diode and the current passing through it. For example, the current passing through is 10A, with a voltage drop of 0.015V and an internal resistance of 0.015V/10A=0.0015 ohms. Attention should be paid to the impact of voltage drop on the circuit.Packing ListDiode module * 1 (optional style)Heat shrink tubing * 1
