In D45 system, there are two types of power supply:
323005 and 323010 .
323005

From above table, the biggest feature of 323005 is that: it’s
capable of supplying power to the data communication
cable, and offer impedance matching for the audio channel
at the same time . Therefore, the system power supply is
necessary in any D45 system project .
In the project, item 323005 is normally used as system
power supply; only when the system needs additional
power supply with smart function, item 323005 will be
used as additional power supply; otherwise, the additional
power supply normally used will be item 323010 . For more
information, please refer to chapter: rules for using the
power supply in the system .
323005 Functions
Loaded short circuit protection: if the DC output suffers a short
circuit, the power supply will enter protection status and stop
the voltage output . After the problem is solves, it will come back
to normal automatically . Smart power supply: in system where
various Small EP are connected with the handset, it may happen
that several Small EP will call the handset at the same time . This
will leads to heavy load for the power supply . In this case (Power
supply cannot supply voltage and all devices cannot work);
using a smart power supply will avoid this problem . The smart
power supply will allow a maximum quantity of EP to call the
handset at the same time on the condition that normal power
supply to the system can be assured .
323010 Functions
Loaded short circuit protection: if the DC output suffers a
short circuit, the power supply will enter protection status
and stop the voltage output . After the problem is solves, it
will come back to normal automatically .
Notes on power supplies:
1 .
they should be installed in cool places with good air flow. Please do not use
anything to block the air vents (on two sides and top of box) of the power
supply.
2 .
Please do not connect the power output port of the power supply to any other
power supplies in parallel.
