Normal operation |
The rectifier is automatically set in
floating or boost charge according to battery condition. The load is
directly connected to the rectifier and to the battery, therefore it
must be able to stand the voltage variation due to the charging
conditions. |

|
Emergency operation |
In case of AC voltage loss the battery
assures the load supply.
When AC supply is restored, normal operation is automatically reinstated. |
