1000W on Board DC convertor

TDC-320-12IG Series of 1000W Series DC/DC converter can be installed in electric cars to supply 24V low-voltage DC power to be used for low-voltage equipment. The output terminal can connect a backup 24V battery and DC/DC converter can manage the charging of the backup battery automatically. The casing is fully sealed, water-proof, automotive level temperature resistance and vibration resist.
