Notes
All protection is automatically recovered.
To protect the battery, if the unit needs to be restarted
after low voltage protection, the voltage of DC input
should be above 12V.
To extend the life of the fan, it will stop when there is no
load. The speed of the fan increases as the load increases.
The unit is completely insulated in input and output for
added safety.
