Battery charging current 0,5A / 1A - I
BAT
jumper selectable
Short-circuit protection SCP
Electronic - current limitation and/or activation of the F
BAT
melting fuse
in the battery circuit (failure requires fuse replacement). Automatic
return.
Overload protection OLP
110% ÷ 150% (@25ºC) of power supply, manual restart (the fault
requires disconnection of the DC output circuit)
Battery circuit SCP and reverse polarity
protections
F 5A - current limitation, F
BAT
fuse (in case of a failure, fuse-element
replacement required)
Surge protection varistors
Excessive discharge protection UVP
U<10V (± 5%) – disconnect of connection battery,
configuration by the P
BAT
jumper
