install the Access Point any where with no hesitation
10~12 watts
IP Surveillance
Enterprise, Museum, Campus, Hospital, Bank, can install IP Camera
without limits of install location – no need electrician to install AC sockets.
3~12 watts
PoE Splitter
PoE Splitter split the PoE 48V DC over the Ethernet cable into 5/9/12V DC
power output. It frees the device deployment from restrictions due to
power outlet locations, which eliminate the costs for additional AC wiring
and reduces the installation time.
Power Configuration
In a power over Ethernet system, operating power is applied from a power source (PSU-power supply unit) over the LAN
infrastructure to powered devices (PDs), which are connected to ports. Under some conditions, the total output power required by
PDs can exceed the maximum available power provided by the PSU. The system may a prior be planed with a PSU capable of
supplying less power than the total potential power consumption of all the PoE ports in the system. In order to maintain the majority
of ports active, power management is implemented.
The PSU input power consumption is monitored by measuring voltage and current .The input power consumption is equal to the
system’s aggregated power consumption .The power management concept allows all ports to be active and activates additional
ports, as long as the aggregated power of the system is lower than the power level at which additional PDs cannot be
connected .When this value is exceeded, ports will be deactivated, according to user-defined priorities. The power budget is
managed according to the following user-definable parameters: maximum available power, ports priority, maximum allowable power
per port.
Reserved Power determined by
There are five modes for configuring how the ports/PDs may reserve power and when to shut down ports.
„
Classification mode
In this mode each port automatic determines how much power to reserve according to the class the connected PD belongs to,
and reserves the power accordingly. Four different port classes exist and one for 4, 7, 15.4 and 30.8 Watts.
Class Usage Range of maximum power used by the PD Class Dsecription
0 Default 0.44 to 12.95 Watts Classification unimplement
1 Optional 0.44 to 3.84 Watts Very low power
2 Optional 3.84 to 6.49 Watts Low power
3 Optional 6.49 to 12.95 Watts (or to 15.4Watts) Mid power
4 Optional 12.95 to 25.50 Watts (or to 30.8Watts) High power
