Battery Charger with Additional Power Supply Operation
The Nordelettronica NE287-17A is a 12-V charger for lead, gel, AGM, and LiFePO4 batteries with up to 17 A continuous current. Depending on the battery type, the charging algorithm is set using a DIP switch. When turned on, the green blinking LED indicates which algorithm has been selected. The battery charger operates according to the IUoU curve. After reaching the nominal charging voltage, the subsequent maintenance charge counteracts the battery's self-discharge. It is possible to connect a temperature sensor to the charger and attach it to the battery to optimize the chosen charging algorithm based on the measured battery temperature.
Use as a Power Supply
With available mains voltage (230 V), the charger also operates as a power supply if no supply battery is installed or connected. In this mode, the output voltage is fixed at 13.8 V, and the maximum continuous current is 17 A with a maximum power of 230 W.
Multiple Protection
For safe operation, the Nordelettronica NE287-17A is protected against short circuit, overload, overvoltage, and overheating. With the optionally used temperature sensor, the battery is additionally protected against overheating. On the input side, the system is equipped with a 4-A fuse. With an IP20 protection rating, the charger is protected against touch with the finger and against medium-sized solid foreign objects (diameter ≥ 12 mm) but is not protected against contact with water.
