Power Supply
There are two options for the power supply:
MS450150M:
This model has an integrated power supply. 100 – 240 V AC is connected direct to
the screw terminal (3x 1.5 mm
2
).
MS450154PM-48:
This model supports Power-over-Ethernet according IEEE802.3af. The power
supply is done by an external power supply (MS700675, not included at delivery). The power
supply has a max. output of 65 W and is supplying the switch and the PoE end devices (max. 4x
15 W).
Alternatively the switch (MS450154PM-48) can be supplied via the TP uplink and PoE with power
(Powered Device = PD). The received power (15.4 W class 0) is not only for the supply of the
switch, it can be used also for the supply of the connected end devices (port 1-4) acting as a
Power Source Equipment (PSE).
In this application the following has to be considered:
•
for the power to the connected end devices (PSE) a max. power of
1x 7.5 W (class 2) or
2x 4 W (class 1) is available
•
at the uplink port has to receive a minimum voltage of 46 V DC
Note:
The end devices available on the market today are often not using the complete power
specified in their class. This allows the connection of end devices according class 3 or class 0,
because their real power consumption does not exceed the limit of the MICROSENS switch.
In this case the “Forces Mode” of the power mode is selected via the network management. The
power consumption at the ports is monitored permanent and if the limit of 10 W is reached the
specific port is switched off.
