Description
The ekinex®power supply EK-AB1-TP is a KNX device
for rail mounting which produces and monitors the 30 Vdc
voltage required to operate the bus system. The device
has an integrated choke which provides the decoupling
between the power supply and the information on the bus
line. On a KNX bus line can be connected up to 64 KNX
bus devices. The output is protected from overload and
short circuit. The device can support short interruptions of
the mains voltage (max 200 ms).
Functions
• 30 Vdc SELV power supply for a KNX bus line with max
64 connected devices
• Reset of the connected bus line with a dedicated pu-
shbutton
Main characteristics
• Housing in plastic material
• Mounting on 35 mm rail (according to EN 60715)
• Protection degree IP20 (according to EN 60529)
• Classication climatic 3K5 and mechanical 3M2 (accor-
ding to EN 50491-2)
• Pollution degree 2 (according to IEC 60664-1)
• Weight 150 g
• 4 modular units (1 unit = 18 mm)
• Dimensions 72 x 90 x 70 mm (WxHxD)
Environmental conditions
• Operating temperature: - 5 ... + 45°C

Planning
Planning a KNX bus installation, the use of a 640 mA po-
wer supply unit requires to take into account the following
guidelines:
• the maximum number of bus devices connected is 64;
• the maximum length of a line segment is 350 m, mea-
sured along the line between the power supply and the
furthest device bus;
• the maximum distance between two bus devices can-
not exceed 700 m;
• the maximum length of a bus line is 1000 m, keeping into
account all segments.
At the same bus line can be connected not more than two
power supplies. A second power supply may be necessa-
ry when the installation in distribution boards requires a
particular concentration of the bus devices (tipically more
than 30 units installed within 10 m). In this case a po-
wer supply has to be installed near the group of devices.
Between two power supplies installed on the same bus
line a minimum distance of 200 m is required, measured
along the line.

Mounting
The device has degree of protection IP20, and is there-
fore suitable for use in dry interior rooms. The housing is
made for rail mounting according to EN 60715 in boards
or cabinets for electrical distribution. The installation is in
horizontal position, the correct position is when the KNX
bus terminal is located at the bottom and the terminals
( , L, N) for connecting the mains power supply 230 Vac
are located at the top. For the installation of the device on
the rail proceed as follows:
• with the aid of a tool bring the locking device in the fully
lowered position (1);
• place the upper edge of the rear inner prole on the
upper edge of the rail (2);
• rotate the device towards the rail (3);
• push the locking device upward until it stops (4).
Before removing the device, be sure the bus terminals
have been extracted from their slots. Use a screwdriver
to slide down the locking device and remove the device
from the rail.
wer supply 230 Vac to which the device is connected. The
green LED marked “ON” indicates the device operating.
Reset
The device has a reset pushbutton. After a reset, the bus
line is not powered for 20 seconds and the bus devices
connected are restored to their original condition. During
this interval of time the reset LED (red) is turned perma-
nently on.

Conguration and commissioning
Conguration
The device does not require any conguration with ETS®
(Engineering Tool Software) tool. The application software
APEKAB1TP##.knxprod (## = version) is available in or-
der to add an EK-AB1-TP power supply to an ETS project.
Commissioning
For the commissioning of the device turn on the mains po-
EKINSTGUIDAEKAB1TP
Failure
When the red LED, labeled “I> Imax”, is turned on, this
means that the KNX output is overloaded or short-circu-
ited. The problem can be solved by removing the cause
of the short circuit or by reducing the number of KNX de-
vices connected to the line. After the removal of the pro-
blem only the green LED “ON” is turned on, at this time it
is recommended to reset the line.

Note. When mounting the device in boards and ca-
binets it shall be provided the necessary ventilation
so that the temperature can be kept within the ope-
rating range of the device.
Warning! The electrical connection of the device
can be carried out only by qualied personnel. The
incorrect installation may result in electric shock or
re. Before making the electrical connections, make
sure the power supply has been turned off.
Warning! In order to supply the KNX bus lines use
only KNX bus power supplies (e.g. ekinex EK-AB1-
TP or EK-AG1-TP). The use of other power supplies
can compromise the communication and damage
the devices connected to the bus.
Electrical connections
Main supply 230 Vac
The connection to the 230 main supply Vac is made with
screw terminals ( , L, N) located on the upper front of the
device. Characteristics of the terminal blocks:
• screw clamping of conductors
• maximum cross section of conductor 2.5 mm²
• recommended wire stripping approx. 6 mm
• torque max 0.8 Nm
KNX bus line
The connection to the KNX bus line is made with the ter-
minal block (black/red) included in delivery and inserted
into the slot located on the bottom part of the front. Cha-
racteristics of the KNX terminal block:
• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire
conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm
• color codication: red = + (positive) bus conductor,
black = - (negative) bus conductor
