| Protection | |
| input overvoltage | Unit must be safe for input voltage up to 300 Vac RMS (and up to 430 V peak), need not be operating. Above this level the unit may be damaged. |
| reverse battery polarity protection | Non-destructive reverse battery polarity protection with fuses. Unit shall not sustain damage and shall meet all specifications after fuse replacement. |
| input undervoltage | Unit must not be damaged for all input voltages from 0-300Vac. Shutdown or input current limit or other means may be applied when input voltage is out of normal operating range. |
| output overvoltage 12/24 mode | Unit will shut down if charging voltage is more than target charging voltage + 1 Vdc for more than 2 seconds; unit will restart when voltage leass than target charging voltage for more than 2 seconds. For battery OVP the unit will restart in the same stage. |
| Unit will shut down if charging voltage is over than target charging voltage + 1.5 Vdc for more than 2 seconds; unit will restart when voltage is less than target charging voltage for more than 2 seconds. For battery OVP the unit will restart in the same stage. | |
| charger overtemperature protection | The internal temperature of the charger will be meassured by NTC. Based on these meassurements, unit will shut down if the temperature exceeds 60°C. Unit will restart when environment temperature cools to 55°C. |
