Overview
PS791-2DC power supply adapter
•
DC/DC power supply unit for input voltages from 12 to 24 V DC
and an output voltage of 18 V DC for all SCALANCE W786
devices
PS791-2AC power supply adapter
•
AC/DC power supply unit for input voltages from
100 to 240 V AC and an output voltage of 18 V DC for all
SCALANCE W786 devices
■
Benefits
•
The PS791-2DC and PS791-2AC power supply adapters are
designed specially for the SCALANCE W786 access points
and are integrated direct into these
•
Global application due to wide input voltage range
•
High reliability as power supply is short-circuit proof, secure
against no-load operation and is able to bridge short breaks
in the mains power
•
When the power supply adapter and Power-over-Ethernet
(PoE) are used, redundant power supply of the access points
can be achieved
■
