SCP short-circuit protection
I-st grade - 200% ÷ 250% of supply power – limitation
of current and/or fuse failure in the battery circuit
(fuse-element replacement required)
II – nd. grade - 110% ÷ 150% (@25ºC÷65ºC) of supply
power – current limitation with the PTC automatic
fuse, manual restart (disconnection of the DC output
circuit)
OLP overload protection
110% ÷ 150% (@25ºC÷65ºC) of supply power –
current limitation with the PTC automatic fuse, manual
restart (disconnection of the DC output circuit)
