Product description
The Power Supply System KNX PS640 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+.
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
