| PROTECTIONS | |
| Input Over Voltage | Unit is safe for input voltage up to 150VacRMS (and up to 215Vpeak). Above this level the damage may occur. |
| Reverse Battery Polarity Protection | Non-destructive reverse battery polarity protection with fuses. Permanent damage will not occur and perform after fuse replacement. |
| Input Under-voltage | No permanent damage for 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 | 36Vdc. 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. |
| 48Vdc. 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 charger 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. (different for lithium) | |
| When the battery temperature is over 50 °C, unit will shut down. | |
| Operation temperature | Operating Ambient Temperature range: -10°C to 40°C | Nominal ambient temperature: 25°C |
| (On the heat sink of DC-DC part, if the temperature is over 90 ℃, the Charger Current will be de-rate to 50% ; if the temperature is over 105 ℃, the Unit will be shut down.) | |
| 5～95% without condensation | |
| Noise | Unit requirements: below 50dB (A) measured at 1 m distance with fan full working. |
| Storage Conditions Temperature | -20°C to +80°C |
| Cooling | Fan – thermal and load based |
