Description
The
Power Supply Systems KNX PS640+ and KNX PS640+USB
deliver a 29
V bus voltage for the KNX system and 24 V DC supply voltage for 24 V devices. Spe
-
cial 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 di
-
rectly by means of the key pad.
In addition all functions can be realised via the bus, too, e. g. the transfer of malfunc
-
tion messages and operating data and a time/period reset. Malfunction messages
are stored by the KNX PS640+(USB).
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, Spanish or Dutch
•
Bus connection
for data transfer (e. g. malfunction messages, operating
data)
• Possibility for reset and diagnostics via the bus
• Only
KNX PS640+USB
: USB interface for bus access via PC
Configuration is made using the KNX software ETS. The
product file
can be dow
-
nloaded from the Elsner Elektronik website on

Installation and Commissioning
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• National legal regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is
no longer guaranteed.
The device is only to be used for the intended purpose described in this manual. Any
improper modification or failure to follow the operating instructions voids any and
all warranty and guarantee claims.
After unpacking the device, check it immediately for possible mechanical damage.
If it has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when as
-
sembled and after conclusion of all installation and operational start-up tasks and
only in the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may
occur after publication of these operating instructions.
2.2. Installation
Observe the correct installation. Incorrect installation may destroy the power supply
system or connected electronic devices.
After the auxiliary voltage is applied the device will enter an initialisation phase las
-
ting 5 seconds. During this phase no information can be received via the bus.
