## System Power Consumption

### For BDV 113 08

The power demand of the system comprises the sum of the current demands of all extensions, base stations etc. This total current has to be delivered by the power supply. Choose the one delivering the rated current with a suitable margin for add on equipment depending on the installation site.

#### Base Station Power Demand

To minimise the power dissipation on the serial communication wires EPP should be used extensively. Up to 60 BS can be installed in a cabinet. Short power peaks can be covered by installing a battery cabinet.

The current limit for remote feeding to the BS per IC-LU is 1.5A on the 48V if supplied from the backplane and 2.1A when supplied via an external power input at the front of the connector. The total current for all BS must be less than the power supply(s) capacity. The total 48 VDC load on the power supply has to be calculated as follows.

The table states the current demand in mA for a Base Station depending on the cable length and cable diameter.

#### Power calculation example

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, subtract again 0.5 A for charging the batteries.

Line Equipment | Quantity | Current (mA)
DBC 199 | 32 | 800

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.

### For BDV BS 101 0x

The power demand of the system comprises the sum of the current demands of all extensions, base stations etc. This total current has to be delivered by the power supply. Choose the one delivering the rated current with a suitable margin for add-on equipment depending on the installation site.

#### Base Station Power Demand

To minimise the power dissipation on the serial communication wires, EPP should be used extensively. Up to 4 BS can be connected to the IC-CU2.

The total 48 VDC current load of the BS on the power supply has to be calculated as follows.
