Technical description
Only SMP301-07
In mains operation, the battery charger supplies the battery with a constant charging
voltage. The battery charger can supply a charging current of up to 20 A until a bat-
tery voltage of 12.7 V is reached. The battery charger can supply a charging current
of up to 5 A at a battery voltage in excess of 12.7 V. The charging process for the bat-
tery is shorter if as many consumer units as possible are switched off. Once the bat-
tery is fully charged, the battery charger supplies it with a float charge.
The battery charger has the following safety functions:
• Overheating protection:
The charging current is reduced if the ambient temperature is too high.
• Deep discharge protection:
Battery operation is deactivated if the battery voltage drops below 10.8 V.
