Overview
Ideal for applications requiring different methods of battery charging, the AIMS 12V and 24V Converter/Battery Charger from the Inverter Store is suitable for many applications and battery technologies. This converter charges batteries including open lead acid, AGM, gel and LiFeP04. It’s particularly useful with generators and shore power.
The flexibility of this unit makes it practical for virtually any application. Its reliable high-frequency structure accepts a wide range of input voltages, from 70VAC to 145VAC, to handle unstable inputs. This charger automatically detects 12VDC or 24VDC battery banks for easy use. Its large, 75-amp charging capacity gets the job done fast. This is a great unit for RVs, boats, camping and many other purposes.
These units have also been tested for safety and are ETL certified to UL 458 standards and CSA certified to CSA 22.2.

| 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. |
