low-voltage DC power supply for boats to supply low-voltage equipment. The output
end can be connected to a 12V backup battery, and the DC/DC converter automatically
manages the charge of the backup battery. This product not only has the advantages of
high efficiency, small size, high stability, long life, etc., but also has the characteristics
of high protection level, high reliability, and complete protection functions. It is an ideal
power source for charging electric boats. The product has built-in thermal induction
device, overheating protection function, and automatic recovery. The fully sealed
process, with a protection rating of up to IP67, can ensure that it can work in any complex
environment without causing failure.

Overcurrent protection Output current exceeds peak current to stop output
Output overvoltage
protection See technical parameter
Output undervoltage
protection
After the output voltage is lower than 6V, the output low voltage
fault is reported after 2 seconds of delay, and the output
current is reduced to 30A
Over-temperature
protection Internal 85°C start power drop, 90°C shutdown
Input undervoltage
protection
When the input voltage is lower than the undervoltage point for
more than 1 minute, the output is turned off, and the output is
restored two minutes after the fault is eliminated
Input overvoltage
protection
The input voltage exceeds the overvoltage point, the output
is turned off, and the output is restored after the fault is
eliminated
Short circuit protection
After the output voltage is lower than 6V delay for 10 seconds,
the current drops to a quarter of the rated current ; the short
circuit elimination voltage returns to normal work when it rises
above 6V
Input anti-reverse
connection protection Not working, not damaged, restored after normal wiring
HVIL High Voltage
Interlock
DC-DC stops working when the input plug-in not inserted in
place
Communication
protection
CAN communication is invalid for more than 5 seconds,
automatically stops working (optional)

6 Notes
1. The equipment of this equipment is metal. Please pay attention to reliable grounding
during installation, and the resistance between the casing and the ground shall not be
greater than 1 ohm.
2. The connection of the battery terminals must be reliable and must not be loose,
otherwise it may cause damage to the DC-DC.
3. If you need to connect multiple DCDCs in the same CAN network, you need to check
the Program Coding on the DCDC label to ensure that the last two digits of the
Program Coding of each DCDC are different, support up to 4 DCDCs working on the
same CAN network.
4. The output capacity of the DCDC is 1kW, the maximum output power can be adjusted
through CAN communication, and the maximum output power is set at 500W by
default. The maximum output power can be adjusted by Smart Display.
5. The DCDC body is IP67 rated, the 12V cable is connected to the enclosure. Please
install the DCDC in a sheltered place such as the engine room, and do not install it in
the weather area.
