The EOD voltage at the end of discharge backup in self-
maintenance is 1.05 times the normal EOD voltage at
the end of backup.
Extra charger module current limit setting:
It is possible to set the maximum current of the extra
charger modules to between 0 and 50 A both through
the settings menu shown in Fig. 87 or control software
shown in Fig. 85.
To do so, connect the monitoring software (MTR) to the
UPS (see the connection procedure in the monitoring
software manual).
Follow this sequence to change the currents: Serv-
Setting->Battery Setting->Charge Module Current Limit
(option).
Fig. 85.
Extra charger module maximum current setting.
The total charging current that the system can supply
(C
total
) will be the sum of all of the current that the
power modules can supply on one side (N*C
pm
), plus
that of the extra chargers (M*C
cm
) on the other, as re-
flected in the following formula:
C
total
= N*C
pm
+M*C
cm
Where,
N is the number of power modules and C
pm
the setting
value of the charging current of each module.
M is the number of extra charger modules and C
cm
is the
current value of the charging current of each module.
Therefore, the formula to apply would be:
C
total
≤ 0.2 * Battery capacity (0.2C)
If N*C
pm
≥ 0.2C, the extra charger module will not
supply charging current to the battery.
If N*C
pm
< 0.2C, the extra charger module charging cur-
rent setting should not exceed (0.2C - C
cm
)/M.
Service settings:
The user can select the system’s work mode. If the
system is configured in parallel, it is possible to adjust
the specific parameters, the number of redundant mod-
ules, etc., as can be seen in Fig. 86:
