Requirements
Table 2 shows the iSTAR Edge environmental requirements.
Power Requirements
The standard iSTAR Edge uses a UL Listed 603 External Power Supply, such as
the Software House apS or uses a Power Over Ethernet (PoE or PoE+) injector.
To ensure adequate power, calculate the total power requirements of iSTAR
Edge and its related hardware, as follows.
Add the total current power for components in the system (modules, relays,
optional modules, readers, and wire resistance).
Tables 3 through 6 are provided to compute the current draw of components
attached to iSTAR Edge.
iSTAR Edge Components and Boards
Table 3 shows the power requirements of iSTAR Edge components and
attached boards.
a
RM-4 board has only been evaluated by UL with RM Series readers (RM 1,2,3)
b
RM-4E boards have only been evaluated by UL for use with RM-DCM-2 enclosure.
Depth 4.5" (11.4 cm)
