Description:
The TDC-J series 1.5KW DC-DC converters can be mounted on the electric vehicle to provide 12V / 24V low voltage DC power. Output can be attached to a 12V / 24V backup battery. The DC-DC converter automatically handles battery charge management. Case is fully sealed in a waterproof and dustproof structure, automotive temperature and anti-vibration protected. The DC-DC converter and battery, 12V / 24V battery back-up, low-voltage equipment, and BMS are connected as shown below. The DC-DC converter high voltage DC power input is directly connected to the battery positive and negative, DC output is connected to a 12V battery backup, and then output to the respective 12V / 24V appliances.
