•
Protection against mains overvoltage via varistors.
•
Protection against secondary overvoltage.
•
Protection against overload and short-circuit of outputs via current limitation.
The battery has various degrees of protection:
•
Electronic limitation of the charging current.
•
Short-circuit protection via a self-rearming fuse.
•
Protection against deep discharge of the battery via a relay in series with the battery, so
that its disconnection is guaranteed when the terminal voltage reaches the pre-set
minimum value.
•
Protection against battery polarity inversion.
