DC DC converters

 

On-board DC/DC converter

1. Overview

TDC-320-12IG Series of 1000W Series DC/DC converter can be installed in electric cars to supply 12V low-voltage DC power to be used for low-voltage equipment. The output terminal can connect a backup 12V 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.

Connection diagram as illustrated below. The high voltage DC input of the DC/DC converter connects directly to the positive and negative pole of the battery pack and the DC output connects to the 12V backup battery, then export to all the 12V electrical appliances.
