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:
- If output overvoltage is caused by the power module itself, the power module stops supplying power. When the system recovers from output overvoltage, the power module cannot automatically start supplying power again.
- If output overvoltage is caused by increase of the input voltage received from the external power source, the power module stops supplying power. When the system recovers from output overvoltage, the power module can automatically start supplying power again.
|
| 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. |
