Functions of a 800 W DC power module
| Function | Description | |
|---|---|---|
| Input protection | Input undervoltage protection | In this protection state, the power module is turned off and stops supplying power. When the system recovers from input undervoltage, the power module can automatically start supplying power again. |
| Input overcurrent protection | In this protection state, the power module is turned off and stops supplying power. The power module cannot automatically start supplying power again and needs to be replaced. | |
| Output protection | Output overvoltage protection | In this protection state:
|
| Output overcurrent protection | In this protection state, the output current is limited to a certain value. When the system recovers from output overcurrent, the power module can automatically start supplying power again. | |
| Output short-circuit protection | In this protection state, the power module supplies power intermittently, and the output current is limited to a range. When the system recovers from output short-circuit, the power module can automatically start supplying power again. | |
| Overtemperature protection | When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply. | |
| Hot swapping | The power module is hot swappable. | |
