BAT
jumper selectable
Short-circuit protection SCP
200% ÷ 250% of module supply power - current limitation
and/or fuse damage in the battery circuit (fuse-element
replacement required)
Overload protection OLP
110% ÷ 150% (@25ºC) of power supply - limitation with the
PTC automatic fuse, manual restart (the fault requires
disconnection of the DC output circuit)

protections 5 A - current limitation, F
BAT
fuse (in case of a failure, fuse-
element replacement required)
Excessive discharge protection UVP
U<10,0 V (± 5%) – disconnection of (- BAT) battery,
configuration by the P
BAT
jumper
