| Protection |
|
| Input Over Voltage | Unit must be safe for input voltage up to 150VAC RMS (and up to 215V 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 Under-voltage | 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 over voltage 12/24V mode | 12VDC. Unit will shut down if Vcharging > Vcharging (target) + 1.0VDC for more than 2 seconds; unit will restart when voltage <= Vcharging (target) for more than 2 seconds.For battery OVP the unit will restart in the same stage. |
|
| 24VDC. Unit will shut down if Vcharging > Vcharging (target) + 1.5VDC for more than 2 seconds; unit will restart when voltage <= Vcharging (target) for more than 2 seconds.For battery OVP the unit will restart in the same stage. |
| Charger over temperature protection | The internal temperatures of the charger will be measured by NTC. Based on these measurements, unit will shut down if the temperature exceeds 105°C. Unit will restart when environment temperature cools to 95°C. |
| BTS(Battery Temperature Sensing) | The battery temperature sensor allows the charge controller to continuously adjust charge voltage / charge current based on actual battery temperature. When the battery temperature is over 40°C, unit will reduce the charging voltage to Float voltage, also it will reduce the Max charging current by 10% with every two degree of temperature rise. When the battery temperature is over 50°C, unit will shut down. |
| Environmental |
