Power Supply
The MPA1C1 can be powered from PoE or an external 12VDC
power supply.
Power over Ethernet
The MPA1C1 controller can be powered by Power over Ethernet (PoE -
802.3af). This PoE can supply a total system current of 1070mA
@12VDC.
However the MPA1C1 controller can consume 300mA of current. This
leaves 700mA of total current for the 12VDC external power to eg read-
ers and locks.
See Hardware Specifications beginning on page 39, for further details
on current limits using PoE.
Use of PoE and compliance with safety regulations:
• PoE can be connected if the Ethernet cable is installed only inside the
building.
• If the connected Ethernet cable is (partly) installed outside the
building, then the MPA1C1 must be powered by an external
12VDC Power supply.
The system has not been evaluated by UL when
powered by Power over Ethernet.
