Rated Output Current Manual adjustable  
Current Accuracy ± 6% of full rated output current @25°C, for target currents across the range from 10% rated output (for absorption exit criteria accuracy) to the current limit set point.  
Load Regulation 1.5%  
Battery type selected Four charging voltages can be adjusted manually  
Parallel Outputs Maximum of two AC converter units connected in parallel  
Efficiency 80%  
Input Over/Under Voltage When the voltage is within the input voltage range, the device must be safe.Shutdown or input current limit or other means may be applied when input voltage is out of normal operating range.
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.
Output over voltage Unit will shut down if Vcharging > Vcharging (target) + 1,0Vdc/1.5Vdc/2.0Vdc/2.5Vdc for more than 2 seconds; unit will restart when voltage <= Vcharging (target) for more than 2 seconds.
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.
