Power Out
iSTAR Edge has various ways to provide power to external devices:
The following power outputs combined can provide a total of 1.5A at 12V.
• each of three serial ports
• each of two Wiegand ports
• each of two aux ports, suitable, for example, for motion sensor power.
The relays can be configured by jumper to provide power.
• Each relay is limited to 0.75A by an individual resettable fuse.
• If one load is shorted the individual fuse limits the shutdown to the
shorted load
• Power fed to wetted relay contacts is 12V for PoE or PoE plus and
otherwise is the DC input voltage.
USB provides 500mA at 5V for each device port. Each port has a resettable
fuse, this meets the USB standard and should not be exceeded by a well
functioning device.
If powered by an external DC supply the amount of power available will
depend on that supply, subject to the limits stated above.
PoE and PoE Plus have the following power limits
PoE provides 12.95W with 100 meters of cable between PSE (Power
Sourcing Equipment) and iSTAR Edge
PoE Plus provides 25.5W with 100 meters of cable between PSE and iSTAR
Edge
Cable length is part of the power budget, i.e. a shorter cable increases
available power, e.g. PoE Plus provides about 10% more power with 50
meters of cable between PSE and iSTAR Edge
