Download: 2KW DC/DC converter liquid cooling system
Model No.: ATD2K-320S14-W-TCDUN6000202
1.2 Major function Introduction
1.2.1 DC-DC Converter function
By receiving the control signal from the vehicle controller, the DCDC converter converts the high voltage of the power battery to the low voltage 14V output to meet the charging and load requirements of the subsequent on-board battery, and can realize its own state and load state feedback.
1.2.2 Self diagnosis and multiple protection functions
It has the functions of self diagnosis, input and output overvoltage, undervoltage protection, output short circuit protection, hardware fault protection, over-temperature protection and recovery of the whole machine;
