Description Battery Charger – 75 Amps for 12V Input Voltage 96-145VAC full performance | 70-96VAC automatically de-rate to 50% of full load current Frequency 40Hz to 70Hz Nominal Input Current at Rated Output <9Aac Voltage Measurement Accuracy ±8Vac Frequency Measurement Accuracy ±1Hz OUTPUT Nominal Voltage 12 Vdc auto adjusting | Input voltage 96-145V Output Current 75A for 12V mode Low input voltage 70-96V derated at 50% of output. 37.5A for 12V Rated Output Current Auto sensing to 12V 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 setpoint. Load Regulation 1.50% Current Limit 75-80Amp Dead-Battery Charging 8-14.9Vdc at 100% | 8-29.8Vdc at 100% of rated output current Selectable Battery Type Open Lead-Acid, Gel, AGM, LiFePo4, adjustable Parallel Outputs Maximum of two AC converter units connected in parallel Efficiency 80% 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 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. 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. 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.
