Protection Requirement

Short Circuit Protection:The power supply will be auto recovered when short circuit faults remove.

Over current Protection: The power supply will be auto recovered when over current 90% to 120% faults remove.

Over Voltage Protection: The power supply will be auto recovered when over nominal voltage 150% to 200%  faults remove.

over-temperature Protection : When the temperature exceeds 85℃+/-3℃, the output current of the power supply will auto reduce by half (the output power will reduce by half), and the power supply will return to normal after the temperature is normal.

Reverse polarity Protection : When the positive and negative polarity of the load (battery) joint is reversed, the power supply will be protected without voltage output, and it will automatically return to normal after troubleshooting.
