technician to perform safety checks to determine that the apparatus is in proper operating
condition.
Danger!
Overloading – do not overload outlets and extension cords as this can result in a risk
of re or electric shock.
24 Power sources. This apparatus should be operated only from the type of power source
indicated on the marking label. If you are not sure of the type of power supply you plan to use,
consult your appliance dealer or local power company. For apparatuses intended to operate
from battery power, or other sources, refer to the operating instructions.
25 Power lines. An outdoor system should not be located in the vicinity of overhead power lines
or other electric light or power circuits, or where it can fall into such power lines or circuits.
When installing an outdoor system, extreme care should be taken to keep from touching such
power lines or circuits, as contact with them might be fatal.
Danger! Object and Liquid entry – never push objects of any kind into this
apparatus through openings as they may touch dangerous voltage points or
short-out parts that could result in a re or electric shock. Never spill liquid of
any kind on the apparatus.

2. ABT-PSC48 Power Supply Combiner
The ABT-PSC48 Power Supply Combiner is used to supply electroning equipment with 52 VDC rated
voltage, with a total maximum power of 3,2 kW.
It uses external 800W ABT-PS48800 switching power supplies.
The ABT-PSC48 can work with up to four of ABT-PS48800 power supplies, ensuring their
safe work connection.
The Power Supply Combiner is to be used in cases where emergency battery power is not needed.
The ABT-PSC48 Power Supply Combiner is designed to power ampliers, which are not equipped
with their own PSU, it is also possible to power ampliers equipped with an auxillary DC input.
The maximum conguration of the power delivery system is as follows:
» 1 × ABT-PSC48 – Power Supply Combiner
» 4 × ABT-PS48800 – Power Supply Module
» 1 × ABT-PF4 – Power Supply Modules Bracket

4. Installing and connecting the device
General Notes
Installing, connecting and conguring the devices should be performed in accordance to the
following manual. When connecting DC power cables pay special attention to the polarity. Wrong
polarity will result in PSU or Power Supply Combiner damage. Before powering the system up
check all the connections.
Installation
The device is designed to be mounted in a 19” rack enclosure. The Power Supply Units should be
mounted in a dedicated ABT-PF4 bracket which is then mounted in the rack cabinet.
Connecting the device
Ground the device using the grounding bolt on the lower left side of the rear panel. Next, connect
the necessary number of ABT-PS48800 Power Supply Units to the INPUT DC 52 V terminals placed
on the rear panel of the ABT-PSC48, making sure of the correct polarity.
The diagram below shows the maximum conguration of the power delivery system consisting of
four connected PSUs. Lastly, connect the devices powered by the ABT-PSC48.
NOTE: In order to connect devices drawing more than 30 A bridge an according
number of 52V outputs.
