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.)
