) provides current on trunk lines in active state to public exchange.
The maximum values for telephones result when all LEDs are lit and if available, loudspeaking is on at max. volume.

Power calculation example
The calculation above shows how to calculate the current demand for a given installation. This amount of current has
to be supplied by the installed power supply.

The BDV 113 08 can be equipped with two different
power supplies. The transformer unit supplies an AC
current that is rectified on the backplane in the cabinet.
The available DC current for the transformer unit
is 3.5 A. Using the switched mode power supply with
battery charger a DC current of 5.0 A is available.
To calculate the available current for the telephone sets
subtract 0.8 A for the boards installed in the exchange.
If backup batteries are connected to the BML unit, sub-
tract again 0.5 A for charging the batteries.
