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% of the PSU power, manual restart (failure
requires the disconnection of the DC output)
Battery circuit protection SCP and reverse
polarity connection
F2A- current limitation, the F
BAT
melting fuse (failure
requires fuse replacement)
Surge protection
varistors
Deep discharge battery protection UVP
U<20V (
± 0,5V) – disconnection of battery terminal
