. Protection Information Instruction
There are two types of overload protection.
The first type protection:
in the DC area, when any port is
powering devices that exceed maximum current limit, or the output power of the AC jack exceeds the
maximum AC power output (Overload 1%-10% will work 3mins overload 11%-30% will work 1min; overload
31%-49% will work 1s; overload 50%-100% will work 100ms), and when the vehicle power supply output
exceeds the maximum current, the overload indication and the corresponding interface indicator will flash
simultaneously for 15 seconds. The output of the interface will be automatically shut down immediately, and
other ports will continue to work.
Second type of protection:
When the power output from the DC or AC jack, and the vehicle power outlet
exceeds the battery maximum power output, the overload indicator and the corresponding port indicator
will flash simultaneously for 15 seconds. EF DELTA will automatically shut down immediately. After an
overload occurs, remove the overloaded device first, and then restart EF DELTA to resume work.
