Power
WBD-111 can be powered by connecting 9-18V voltage power supply to DC jack (see picture above)
or via Ethernet by using power injector. Insertion of power supply connector disconnects Ethernet
power feed line. Device has polarity independent DC-DC converter with overvoltage and overheating
protection, with two onboard SMD fuses. Power jack accepts
DC 1.4/3.4 mm
coaxial power
connectors.
