8.0 C-Bus Power Requirements
The Matrix Switcher has a built-in C-Bus Power Supply which provides
330 mA to the C-Bus network. Multi Room Audio Amplifiers draw 22 mA
from the C-Bus network.
The Matrix Switcher supplies enough C-Bus power for at least seven Multi
Room Audio Amplifiers and seven C-Bus wall switches (such as the Ulti
Saturn or DLT).
The Distribution Unit does not connect to C-Bus and therefore does not
impact on the power requirements of a C-Bus network.
The Network window of a C-Bus Toolkit project provides a summary of a
C-Bus network according to the units added to the Database. This can be
helpful in determining the power supply requirements of a particular
network.
9.0 Power Surges
External power surge protection devices should be used to enhance
system immunity to power surges. It is strongly recommended that
overvoltage protection equipment such as the Clipsal 970 Series be
installed at the switchboard.
