ChargeMaster Plus 12/75-3, 12/100-3, 24/40-3, 24/60-3 – User and Installation Manual
5.5 Smart terminal - Output 3
The ChargeMaster Plus is equipped with three full outputs.
The total output current is divided over these three
outputs. See section 3.6 for connections.
Output 3 is the Smart terminal, which can be current
limited and can serve as an output and as an input to
charge battery 1 & 2. See also section 4.1 on page 14.
The Smart terminal has the following operating modes:
•
10A starter
•
Starter
•
S alternator
•
Follow main
•
Follow main + alternator
•
12V constant voltage
•
24V constant voltage
•
12V 3-step+
5.5.1 10A starter
Outputs 1 and 2 are configured as full outputs. Smart
terminal 3 is current limited to 10A to safely charge a
starter battery.
5.5.2 Starter
Outputs 1 and 2 are configured as full outputs. Smart
terminal 3 is current limited to be able to charge a starter
battery. A 24V charger can charge a 24V starter battery, or
a 12V starter battery with its own charging profile. Settings
are configured via MasterBus, see section 4.2.
5.5.3 S alternator
Outputs 1 and 2 are configured as full outputs. Smart
terminal acts as a VSR (Voltage Sensitive Relay). When
there is no AC power available and the alternator is
charging the starter battery, the alternator can also be
used to charge batteries 1 and 2. The threshold voltage
which is used to switch over can be configured via
MasterBus, see section 4.2.
5.5.4 Follow main
Operation mode for 3 batteries, the charger is configured
with 3 full outputs. All batteries are charged with the same
settings.
5.5.5 Follow main + alternator
Operation mode for 3 batteries, the charger is configured
with 3 full outputs. All batteries are charged with the same
settings. Smart terminal acts as a VSR (Voltage Sensitive
Relay). When there is no AC power available and the
alternator is charging the starter battery, the alternator can
also be used to charge battery 1 & 2. The threshold
voltage which is used to switch over is configured via
MasterBus, see section 4.2.
