Protection
The battery charger is safe to use due to its robust design and its internal electronic
protection. This chapter describes the various internal electronic protective devices.
Maximum charge current protection
The battery charger provides a maximum charge current of 30A for the 30A charger,
50A
for
the
50A
charger
or
100A
for
the
100A
charger.
This level is electronically limited and is factory set.
The maximum output current can also be limited by using an external potentiometer-
panel, the Victron Energy COV panel.
Short circuit protection
The charger output is protected against short-circuits. The short-circuit current is
electronically limited at 30A, 50A or 100A, according to the model. In this condition
the output voltage approaches 0 Volt. The battery charger resumes normal operation
when the short circuit is removed.
The short circuit current can also be reduced by the Victron Energy COV panel.
Input protection
The charger mains-input is protected with a fuse.
The charger will not be damaged by using input voltage between 0 and 300 Vac.
The charger will not be damaged by using input frequency between 0 and 65 Hz.
Over voltage protection
The charger switches off automatically when the battery voltage becomes higher
than the over voltage value. The charger switches back on when the battery voltage
becomes less than the raise value. See the table below.

The charger output is protected with a fuse.
Starter battery protection
The output current of the starter battery output is electronically limited at 4A. The
starter battery output is also protected against wrong connections by means of a 10A
fuse.
