KNX PowerSupply 365
(Art. # 5335)
640 mA power supply for KNX bus
KNX PowerSupply 365
Application
The KNX PowerSupply 365 is a 640 mA bus power supply with
high efficiency and small footprint of only 4 modules (72 mm).
The device has an integrated bus choke and also provides an
output for auxiliary voltage.
Three multicolor LEDs on the front indicate the condition of the
device. They signal overload with warning, exceeding tempera-
ture and telegram traffic and the reset status.
The two buttons enable the KNX line to be reset.
Installation and commissioning
The KNX PS 365 is mounted on a DIN rail and has a space
requirement of 4 modules. It has the following controls (❼❽)
and displays (❹❺❻):

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.
Settings
The device requires no settings and does not occupy any KNX
addresses.
Display of the status LED
LED „Current" Meaning
output
LED lights green The device operates in normal operating mode.
Sum of the output currents < 600 mA
LED lights yellow The device operates in normal operating mode.
Sum of the output currents 600 mA < I < 640 mA
LED lights red overcurrent
Sum of the output currents I > 640 mA
LED flashes red Critical overcurrent
Sum of the output currents I > 900 mA
LED „Temp." Meaning
temperature
LED lights green The device operates in normal operating mode.
Temperature in the housing < 60 ° C
LED lights yellow The device operates in normal operating mode.
Temperature in housing > 60 ° C and < 75 ° C
LED lights red Overtemperature
Temperature in the housing > 75 ° C
LED flashes red Critical overtemperature
LED off If the temperature increases further, the unit switches
off for safety reasons. In this case, a display on the
device is no longer possible.
To restart, the unit must cool down and be discon-
nected from the mains for a short time (about 10 s).
LED „Traffic/ Meaning
Reset"
LED lights green No telegram traffic
LED flickers green Telegram traffic with bus load < 70%
LED flickers yellow Telegram traffic with bus load > 70%
LED lights red Reset active
Can be stopped manually or automatically.
