3.1.2.1.Power supply

The JUPITER+ Transmitter runs on 7,2Ah 12V DC batteries.
When turned on, the charge level of the battery is indicated on the
front face.
The minimum autonomy of the transmitter is 8h.
The transmitter can run on internal batteries or during the charge when
using the external charger connected to the front connector closed to
the case handle.
The charger operates in three modes
LEDs):
• BOOST Mode, starts automatically on connecting the charger
to the mains if the battery is discharged. The current delivered
by the charger is then at maximum. The BOOST mode
enables the supply of up to 80% of the battery capacity and
can support the impact of loads due to transmission when the
Transmitter is active.
• ABSORPTION Mode, starts as soon as the battery voltage
has reached the maximum value of the BOOST. The current
then begins to reduce. The duration of the two phases
together (BOOST + ABSORPTION) will be a function of the
initial discharge state of the battery and whether the
Transmitter is activated or not. At the end of the absorption
phase, the battery is recharged to 95%.
• FLOATING Mode, at the finish of the two initial phases
(BOOST
configures in FLOATING mode. The value of the current
delivered
approaches zero. This phase corresponds to holding the
batteries in charge (trickle current).
