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

The programme file for KNX software ETS (format VD2) is ready for download on the
