The Plena Mixer Amplifier has a 24 VDC input (terminal screw). This input can be used in mobile applications, such as boats where 120 or 230 VAC is not available or in applications that must continue to operate in case of a power failure.
When a 24 VDC battery is connected (typically consisting of two 12 VDC
The Plena Mixer Amplifier has as a built in charger, which charges the connected battery (or batteries if connected in series). A separate battery charger is, therefore, not required. The charger charges the battery with a 0.5 A constant current until the battery voltage reaches 27.4 VDC. The charger then switches over to constant voltage charging (also known as float charging). This means that a battery can be charged at the same rate it is discharging, and thus full capacity battery can be assured.
This type of charging is suited for low
Note
If battery charging is not required, the 0.5 A maximum output current can be used for volume overrides or other purposes instead.
