5.2. Description of components and electrical contacts of the power supply unit.
The LED display with buttons on the front panel of the power supply allows signaling the status of the
power supply and displaying the basic parameters. Panel functions and operation are the same in all available
models.
Fig. 16. Front panel of the power supply unit.
The figure below shows the rear panel of the power supply in the maximum configuration, i.e. the connector for
the two battery strings and the 9 outputs for the audio amplifiers. In other versions, the power supply can be equipped
with a connector for connecting one battery string and 5 outputs for connecting audio amplifiers.
