Power Supply PS791-2DC and PS791-2AC

■

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

■

Design

• Integral power supply adapter for SCALANCE W786

• Fan-free design

• Operating temperatures from -40 °C to +60 °C

• Resistant to condensation
