– 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.

Average power requirements of terminals
Tip
With the planning application Mitel CPQ the power supply available for terminals is checked
automatically.

Power supply per terminal interface
The power supply per terminal interface is determined by the interface type. The inter-
face load depends on the following variables:
• Terminals used incl. auxiliary devices
• Bus configuration
• Line length and conductor cross-section
