3–6 iSTAR eX Installation and Configuration Guide
iSTAR eX Input Power Rating
The iSTAR eX has the following input power ratings when using the internal
power supply:
100 - 240 VAC
6.2 Amps
60 Hertz
The iSTAR eX has the following input ratings when using an NPS external
power supply:
12 VDC
6 Amps
Individual/Total Loads evaluated by UL
RS-485 Reader Power Outputs: 10.6-12.5 VDC, 350 mA max each; total of
RS485 reader outputs combined not to exceed 2.8 A.
Wiegand Reader Power Outputs: 10.6-12.5 VDC, 350 mA max each; total
of Wiegand reader outputs combined not to exceed 1.4 A.
Total of all reader outputs combined (RS-485 & Wiegand) not to exceed
2.8 A
Four (4) activated relay coils – GCM board = 100 mA
One I/8 module – 12 VDC, total= 125 mA
One R/8 module – 12 VDC, total= 325 mA (125 ma + 25 mA for each
active relay (max 8))
R/8 relay contact ratings – 30 VDC at 2A (resistive)
Max output load = eight (8) readers (2.8 A) + one (1) I-8 module (125 mA)
+ one (1) R-8 module (325 mA) = 3.25 A
