Applications
1. Dual-power-supply parallel configurations and UPS applications.
2. Redundant power supply applications.
3. Parallel connection of primary and secondary batteries.
4. Uninterrupted battery replacement for drones, electronic devices, etc.
5. Backfeed protection for batteries, solar systems, and power modules.
6. Reverse polarity protection for DC electronics, power modules, and electronic devices.
Precautions
1. The negative terminal of the main current circuit does not need to pass through the module, but the negative terminal on the module must be connected (a thin wire may be used).
2. This module is for DC applications only, with a switching frequency not exceeding 150 Hz; it cannot be used for AC rectification.
3. Be aware that surge voltages can cause chip breakdown. For high operating voltages or inductive loads, install
TVS diodes and electrolytic capacitors at the input and output to absorb surge voltages.
4. When operating currents are high and heat generation is significant, enhance heat dissipation (by using a larger heat sink or air cooling).
5. Multiple modules can be connected in parallel to increase current capacity or to expand the number of channels.
6. When connecting a primary and secondary battery in parallel, if the primary battery does not have an ideal diode connected, ensure that the secondary battery voltage
does not exceed the primary battery voltage. If both the primary and secondary batteries have ideal diodes connected, there are no voltage
difference requirements when connected in parallel.
7. Do not use the diode or resistance ranges on a multimeter to measure the internal resistance of an ideal diode; this is an incorrect measurement
method; the internal resistance can be calculated using the voltage drop across the ideal diode and the current flowing through it. For example: if the current is 10 A and the voltage drop is 0.015 V, the internal resistance = 0.015 V / 10 A = 0.0015 ohms. Be sure to account for the effect of circuit voltage drops.
