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 50A for the 50A charger,
80A for the 80A 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 50A, 80A 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 voltage 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.

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.
