The AIMS Power AC Converter / Battery Charger / Power Supply 12V/24V is ideal for applications that require diverse ways of recharging batteries. There are many ways to recharge batteries and the wide AC input range of this unit accommodates most applications and battery technologies. Useful with generators and shore power, this converter charges various types of batteries such as open lead acid, AGM, Gel and LiFePO4.

The reliable high-frequency structure accepts a wide range of input voltages of 70 VAC to 145 VAC to accommodate unstable inputs. The unit also auto-detects 12 VDC or 24 VDC battery bank. The AIMS Power AC Converter / Battery Charger provides the flexibility for almost any application and the large charging capacity of 75 amps gets the job done quickly.

Perfect for RVs, boats, campers and much more.

Input Over VoltageUnit must be safe for input voltage up to 150VACRMS (and up to 215V peak), need not be operating. Above this level the unit may be damaged.
Reverse Battery Polarity ProtectionNon-destructive reverse battery polarity protection with fuses. Unit shall not sustain damage and shall meet all specifications after fuse replacement.
Input Under-voltageUnit 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 protectionThe 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

Nominal ambient temperature: 25°C

Operating Ambient Temperature range: -10°C to 40°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.)
