5.2 Calculating the Power Consumption
The following facts are important for the choice of power supply units for 52/RX Mixing Consoles.
· Use two 52-5048 power supply units for larger mixers with redundancy option inside the 52-5081 or 52-5083 power
supply frames. The maximum power consumption in total is 200W.
· Use two 52-5048 power supply units for several smaller mixers with redundancy option inside the 52-5081 or 52-
5083 power supply frames. The maximum power consumption in total is 200W.
· You may also use two 52-5047 power supply units for smaller mixers with redundancy option inside the 52-5081 or
52-5083 power supply frames. The maximum power consumption in total is 100W.
· Use the 52-4048 desktop power supply for smaller mixers in non redundant installations. The maximum power
consumption in total is 100W.
· PoE switches are not included in all 52/RX fader and control modules or table installation frames.
· Use 52-4080 PoE switches mounted close to the console or 52-5088 PoE switches inside the 52-5083 power supply
frames.
Important
There are two 48V connectors on each 52-4080 PoE switch. At revision A of the
PoE switch (52-4080A), the second speakon connector can be used to chain to
another 52-4080. Do not connect two power supplies to a 52-4080A to achieve
redundant power supply! There is no diode included in the 52-4080A!
Revision B of the PoE switch (52-4080B) provides the option to connect a
redundant power supply to the module. Nevertheless, in revision B it is still
possible to connect through the PoE switch to another PoE switch. Please take
care about the internal wiring!
