5.2 Powering user panels
5.2.1 V-Series panels
V-Series panels, including expansion panels, have an external DC power supply.
The power supply is universal, operating over a voltage range of 100 - 240 VAC at 50 - 60
Hz. The maximum dissipation is 50W.
5.2.2 I-Series panels
I-Series panels have an internal power supply, with a removable AC power cable.
The power supply is universal, operating over a voltage range of 90 - 245 VAC and
50 - 60 Hz. The maximum dissipation is 40W.
5.3 Powering interface frames
5.3.1 IMF-3
The IMF-3 interface frame requires an external PSU-101 power supply
(see Figure 2: PSU-101 power supply for IMF-3).
Usually, one PSU-101 power supply unit is required for approximately every two IMF-3
frames. This requirement may differ where:
• The IMF-3 is hosting a large number of CCI-22 paryline interface modules,
which require no DC power from the IMF-3 frame (the modules are powered from
the partyline connection).
However, even if the IMF-3 only contains CCI-22 interface modules, a PSU-101
power supply is still required to power the circuitry on the rear panel of the IMF-3.
• The IMF-3 is hosting multiple TEL-14 telephone interface modules. An IMF-3
interface frame can only power eight TEL-14 interfaces on one PSU-101 power
supply. If more TEL-14 interface modules are required, they must be installed in a
second IMF-3 frame with a second power supply.
