4.4.1 Power source
The power source for the SAILOR 6110 GMDSS System consists of a 24 V battery
system and an AC power source.
A suitable power supply, the SAILOR 6081 PSU and Charger, is delivered with
the system.
If you are using the SAILOR 6081, connect the power wires in the CAN bus from
the GMDSS Terminal to the 15 V DC output from the SAILOR 6081 PSU and
Charger. Other units in the system may be connected to one of the standard DC
outputs in the power supply. For power requirements from these units, refer to
the specifications in their respective installation manuals.
4.4.2 Calculating power cables for the SAILOR 3027
The SAILOR 3027 GMDSS Terminal has one CAN connector, which is also used
for power input. If possible, use the cables included with your SAILOR 6110
system. See
Wiring overview on page 28.
If you want to use other cables, use the guidelines in this section to calculate
the maximum length of your power cables. Note, however, that the maximum
length of cables between the GMDSS Terminal and the power supply must not
exceed 55 m.
Source impedance
The length of the power cable depends on the type of cable used and the
source impedance of the DC power source.
The maximum allowed source impedance depends on the utilization of the
power range of the DC input (9 - 32 V DC; 2.8 - 0.8 A for the SAILOR 3027).
Note
If you are not using the SAILOR 6081 you must provide a voltage
monitor for your power supply.
