Product description
The Power Supply System KNX PS640-IP combines the central functions of a KNX bus
line:
Power supply with throttle and bus communication
IP router and IP interface
The device has got two KNX interfaces, one for the “PLUS” functions of the power
supply unit and one for the IP router. The functions are registered at the bus separately
and parametrised in different product files (ETS).
The power supply unit of the KNX PS640+IP delivers a 29 V bus voltage for the KNX
system and 24 V DC supply voltage for 24 V devices. Special operating conditions such
as short circuit, electrical surge, overcharge or excess temperature are recorded and
may be read off on the display. The present power discharge is displayed as well. It is
possible to reset the connected bus devices directly by means of the key pad.
In addition all functions can be realised via the bus, too, e. g. the transfer of malfunction
messages and operating data and a time/period reset. Malfunction messages are stored
by the KNX PS640+IP.
The IP router of the KNX PS640+IP allows for forwarding of telegrams between
different lines via a rapid LAN (IP) backbone. The KNX PS640+IP therefore also takes on
the function of a line coupler.
In parallel, the KNX PS640+IP can be used as interface for accessing the bus via IP.
Like this, the KNX system can be configured and supervised from any PC in the LAN
(Tunnelling). Access via smartphone (KNX app) is also possible.
This device works according to the KNXnet/IP specification using the core, the device
management, the tunnelling and the routing part. The router of KNX PS640+IP has a
filter table and is able to buffer up to 150 telegrams.
Functions:
Delivers a 29 V KNX bus voltage (reduced), output current max. 640 mA, short-
circuit proof
Delivers 24 V DC (not reduced), output current max. 150 mA
Reset of a line directly on the device
Record of operating hours, overload, external overvoltage, internal overvoltage,
short circuit and excess temperature
Display of operating data bus voltage, bus current and temperature of the device
The display may be shown in German, English, French, Italian, Spanish or Dutch
Bus connection for data transfer (e. g. malfunction messages, operating data)
Possibility for reset and diagnostic via the bus
Routing: Transfer of KNX data via LAN (rapid backbone)
Line coupler function via LAN
Tunnelling: Configuration and supervising of the KNX system from any PC in the
LAN, access via smartphone (KNX app)
