KNX PowerSupply USB 367
(Art. # 5219)
640 mA power supply for KNX bus with integrated bus choke, KNX node,
diagnostic / logic functions and USB Interface
KNX PowerSupply USB 367
Application
The KNX PowerSupply USB 367 is a 640 mA power supply with
high efficiency and a small footprint of only 4 units (72 mm). The
device has a bus choke and additionally provides an output for
auxiliary power. An integrated USB Interface (connector Micro
USB) allows the easy connection of a laptop or PC.
The integrated KNX node monitors output current, bus voltage
and the temperature in the enclosure. Various logic functions
complete the feature set of this device. The configuration is done
with the ETS®. An easy to read OLED display on the front panel
enables you to display the operating parameters locally on the
device.
USB Interface
The KNX Power Supply USB 367 has an integrated KNX USB
Interface for bus access. It is used for programming with ETS®
(ETS3 or higher).
Via the integrated USB interface the KNX Power Supply USB
367 can be programmed locally with ETS5.5 (or higher).
The integrated USB interface supports KNX Long frames for a
faster download in KNX devices that support long frames.
Installation and Connection
The KNX PS USB 367 is designed for installation on DIN rail with
a width of 4 units (72 mm). It features the following controls

Mains connection
When connecting the mains voltage, the protective conductor
(PE) must be connected, as it is used to equalize the potential of
the bus voltage.
Output bus voltage (KNX)
The bus voltage is used to supply KNX devices for the medium
twisted pair. The integrated bus choke separates the DC supply
voltage from the bus signals.
Output auxiliary voltage (30 V)
This output is used to supply additional equipment. The output is
galvanically connected to the bus voltage, but is not at the same
potential. This means that "minus" bus and "minus" of the auxil-
iary voltage are not the same and must not be connected to
each other. If required, the auxiliary voltage can be routed to the
load via the second wire pair (yellow / white) of the KNX cable.
All data on the output current relate, unless otherwise stated, to
the sum of the currents of bus voltage and auxiliary voltage.
Access of settings/status
The settings/status of the device can be accessed/viewed via
1. Direct setting/status display on the device (partly)
2. ETS (Version 4.2 or higher)
The KNX Programming Mode is activated/deactivated
by simultaneously pressing the buttons
activated the programming LED
Thanks to the integrated USB interface a laptop or PC
can be connected via the micro USB
Programming and status LED
The red LED on the front panel is used to display the KNX pro-
gramming mode and errors. The LED can have the following
states:

LED off: The programming mode is not active and
there is no error (normal operating mode).

LED lights up: The programming mode is active,
any errors are not visualized/notified by the LED,
but can be read on the display.

LED flashes quickly: The programming mode is
not active. The rapid flashing indicates one of the
following faults:
o
Overload (sum of the current of auxiliary
and Bus power)
o
The device is not loaded correctly, for
example, cancelled a download.
