VIDEO POWER SUPPLY REF. NO 1752/20D
GENERAL INFORMATIONS
Video Power Supply Ref. no. 1752 / 20D is
designed for installations of MATIBUS SE system
with the video.
The main features include:
• Ensuring energy efficiency for video installations,
• Commutation main bus data connections
and the secondary bus data for rise I and II.
• The ability to integrate video amplifier regulated
to the risers.
• The ability to quickly connect up to 3 panels
keyboard input, additional or principal.
In addition, the power supply has a green LED
indicating connection status to the mains.

USER MANUAL
JUMPERS P1, P2, P3, TER i AMP
In the power supply 1752 / 20D panels can be easily change
from the main bus data to secondary bus data and vice
versa.
To do this, attach a suitable jumper P1, P2 and P3,
respectively, for the panel 1, 2 and 3.Then the data line,
audio and video signal will be automatically redirected to
the correct bus data.
• No jumper means panel working on the secondary bus
data,
• Established jumper means panel working on the main bus
data
The jumper marked TER is permanently turn on termination
video signal in the main bus data.
The jumper labeled as AMP permanently turn on video
amplifier to both divisions.
VIDEO AMPLIFIER
The amplifier can increase the range of video transmission
in the risers 1 and 2. At longer distances, switching
amplifier improves the quality of the video signal.
Switching amplifier is performed by setting jumper AMP
.
