Introduction
Introduction 1
General description
The TT-6080A AC/DC Power
Supply can deliver 300 W
output power on average
with a peak of 370 W for a
minimum of 2 minutes.This
is useful for MF/HF
applications and DSC
transmissions of 2 minutes
duration. It is AC powered
with a battery switch-over function. The AC/DC Power Supply has an on/off
switch. It is lit when the power is turned on.
All connectors are placed at the same end of the power supply to simplify
mounting and installation. The connector panel is protected by a transparent
lid. To secure an installation with heavy cables a cable-relief bracket can be
installed.
When mounted vertically the AC/DC Power Supply fulfills IP32 in areas with
more than 42 V and IP22 in other areas. This means that the unit is protected
against the intrusion of solid objects (including body parts like fingers), dust,
water etc.

Chapter 1: Introduction
2Features
Features

Output power 300 W continuous, 370 W peak (2 min., 100-240 VAC) or
270 W continuous, 333 W peak (2 min., 90-100 VAC)
AC input (100-240 VAC operating) with fuse (6.3 A)
Automatic selection of input voltage range
AC alarm and On/off switch
Daisy-chaining of up to three units to give up to 900 W.1
Short circuit protection
Over-temperature protection (shutdown with automatic restart)
Battery switch-over in case of AC supply failure, secured by 2 fuses (30 A)
No forced cooling required
IP 3X for internal high voltage areas (>42 V), IP 2X in other areas
IP X2 when vertically mounted (wall) and connector panel is facing down
1. Output power capability depend on the mounting position (horizontal or
vertical), input voltage, ambient temperature and ventilation at the place of
installation.

4 Applications
Applications
The AC/DC Power Supply is designed
to be used with BGAN-X and
FleetBroadband terminals. It can be
used as a stand-alone DC power
supply or as a building block in a
larger power supply.
When more power is needed than one
power supply can give, i.e. 300 W, you
can stack up to three power supplies
on top of each other and connect them.
When stacking 2 or 3 units the load on
each of the units is automatically
balanced among the units.

6 Installing the AC/DC Power Supply
Installing the AC/DC Power Supply
You can mount the power supply in a vertical or horizontal position. When
mounted in a vertical position, with the connector panel pointing downwards,
the unit fulfills IP32 in areas with more than 42 V and IP22 in other areas.
Connector overview
Warning! Never insert or remove a power supply while its power
switch is in the On (|) position. Make sure the power
switch is Off (O) first.
Important
To ensure adequate cooling of the AC/DC Power Supply an
unobstructed space of minimum 5 cm must be maintained
around all sides of the unit except for the bottom side.

8 Installing the AC/DC Power Supply
To install the AC/DC Power Supply, do as follows:
1. Install the cable-relief bracket, if required. Align it with the connector row
of the AC/DC Power Supply.
2. Fasten the cable-relief bracket directly to the wall, between the wall and
the AC/DC Power Supply, with four M4 x 6 mm screws.
3. Fasten the AC/DC Power Supply to the wall with 4 mounting bolts,
M6X55 mm, DIN912 Unbrako (included the delivery).
An optional, larger Wall-mount tray, heavy duty, is available for the AC/DC
Power Supply. For further details see Wall-mount tray (option) on page 25.

Protective lid for the connector panel
The connectors are protected
by a plastic lid. To access a
connector you have to
remove the lid. To make
room for the connector
cables you must remove the
U-shaped cutout for the
respective cable in the
plastic protective lid.
Removing the protective lid
To connect the cables you
must remove the protective
lid.
To do this, unscrew the two
screws (M3x7mm” Torx-8)
as shown in the picture and
put the lid aside.
Inserting the cable in the spring terminal connector
The connectors are spring-ter-
minal connectors. Use a suit-
able tool to open the spring and
insert the cable in the opening
below.

Connectors
AC input
The AC/DC Power Supply is typically AC powered. To connect the AC input do
as follows:
1. Connect the Mains cable to the connector marked MAINS AC.
2. Remove the u-shaped cut-out for this input from the protective lid.
3. In order to be able to daisy-chain up to three AC/DC Power Supply units the
Mains AC connector has two terminals:
• Use one terminal for the incoming mains power.

Power Supply.
DC output
The AC/DC Power Supply supplies a DC output. To connect the DC output DC1
do as follows:
1. Connect the DC cable to the connector marked DC1 and the equipment that
must be powered.
2. Remove the u-shaped cut-out for this input from the protective lid.

12 Installing the AC/DC Power Supply
When connecting 2 or 3 units in parallel, the combined power may be drawn
from a single connector. A single connector can handle 30 A.
DC output or optional input for daisy-chaining
The second DC connector (DC 2) of the AC/DC Power Supply can be used for 2
purposes, to provide DC output or to serve as an input connector when daisy-
chaining up to 3 AC/DC Power Supply units.
To connect to DC2 do as follows:
1. To have a second DC output:
Connect the DC cable to the connector marked DC1 and the equipment that
must be powered.
2. To daisy-chain a second AC/DC Power Supply.
Connect the cable from DC1 in AC/DC Power Supply unit 1 to DC2 in AC/DC
Power Supply unit 2.
Connect the DC cable to the connector marked DC 2 and the equipment
that must be powered.
3. Remove the u-shaped cut-out for this input from the protective lid.
To daisy-chain a third AC/DC Power Supply repeat step 2. The connector
specifications are the same as for DC1.
To see an overview how to connect AC/DC Power Supply units in a daisy chain
see Wiring for daisy-chaining on page 16.
Caution! If you need more than 3x300 W or 30 A you need
to follow special guidelines when connecting the
required AC/DC Power Supply units. Refer to
Wiring four or more AC/DC Power Supply units on
page 27 to see how to connect the AC/DC Power
Supply units to meet these requirements.
