Supply Power Available For Terminals - Mitel 430 System Manual

Supply power available for terminals

The 40 VDC power supply required for the connected terminals is rated for the power
requirements of a typical system configuration.
Tab. 32 Power output of the 40 VDC power supply
Available power output
The number of permissible terminals per system depends on the power requirements
of the individual terminals. To check the power requirements refer to Tab. 33 for details
of the average power requirements of the terminals.
The total power requirements of all connected terminals must not exceed the available
power output of the power supply.
Note
The actually required power supply depends strongly on the call traffic, the wire diameter and
the line length to the connected terminals. The values in the following table are average values
under the following assumption:
– Phones traffic volume: Call Connection 38%, Ringing 2%
– SB-4+ radio unit: Active call connection on 2 channels
– SB-8 radio unit: Active call connection on 4 channels
– Background lighting MiVoice 5380: 30% active
– LEDs on terminals and expansion key modules: 20% active.
– Wire diameter: 0.5 mm
– Line length: 200 m
The table below shows the average power requirements of the terminals for a line
length of approx. 200 m and a wire diameter of 0.5 mm.
