Figure 7:Example PSU-101 to IMF-3 connections
Installing two PSU-101 power supplies for each IMF-3 provides redundancy, because either
of the two PSU-101 power supplies can power a complete system.
If one fails, it can be removed without interruption of the entire system. Rear panel
connectors provide easy parallel connection to the IMF-3 interface frame.
A PSU-101 requires 90 - 260 VAC at 45 - 65 Hz with a maximum dissipation of 80W.
PSU-101 alarm
An audible alarm is included in the PSU-101, and an additional set of alarm-relay contacts
are provided on the supply.
Clear-Com recommends that these contacts be connected to the external alarm input of the
matrix frames. If any of the power supplies in the PSU-101 fails, a system alarm is activated.
LEDs on the front of the PSU-101s indicate the failure.
Tip: For more information about the IMF-3, see the IMF-3 manual.
