Using External Power Supply at Transmitter Only
This section looks at the scenario where only a 60 W external power supply (such as the POWER-60W power supply) is
connected to the transmitter. No other power is provided to the receiver.
Note: it is possible to provide power to the receiver through another separate power supply. This can be done in cases where
additional power is needed at the receiver in order to power the end device. Powering the receiver will not provide power to
the transmitter. See the "Using External Power Supply at Receiver Only" section for more information on this use case.
Table 3 provides guidance as to the maximum distance between the transmitter and receiver when only the transmitter is
powered by a 60 W external power supply.
● The "Max Wattage at PD" refers to how much power is available at the Powered Device (PD)
● The amount of power needed is dependent on the requirements of the Powered Device (such as
a security camera)
● The "TX1 – RX1 Cable Distance ft. (m)" refers to how far the transmitter and receiver can be
separated from each other with either 23 AWG cable or 24 AWG cable
● Panduit recommends 23 AWG cable as it provides further distance
● In all cases, we recommend no more than 50 feet (15 meters) from the transmitter and receiver
and the corresponding devices they are connected to
● In the case where a 4-port receiver (POEXRX4) is connected to the transmitter, the "Max Wattage
at PD" must be split amongst the four ports, offering a lower total power available per port
As can be seen from the table, for example, Panduit can only supply up to 25.5 W at 1,263 feet with 23 AWG cable.
