Dual power sources

Typical Reader Controller install
with:
• Redundant power supplies
• Input power: PoE
• Input power: 12VDC
Solution highlights
• Improve the ACS fault-tolerance
design by supplying the Reader
Controller with electrical power
from two independent power
sources.
• With this design, if the Reader
Controller's connection to the
PoE nework switch is lost, the
Reader Controller will
automatically begin to draw its
power from the DC power
source.
