The KNX-PS640 power supply unit enables the KNX bus to be supplied with system voltage

(SELV). The output with integrated choke makes it possible to separate the power supply

from the KNX bus communication line.

1. Features

Wide input voltage range: 195…265 V AC (50/60 Hz).

Output voltage for the bus: 28…30 V DC.

Short-circuit protection for AC power input.

Short-circuit and overload protection for DC power output.

LED indicators of power supply operating status.

Installation in electrical cabinets, on DIN rail (35 mm).

2. Description

230 V AC mains connection terminals ( – terminal for connecting the protective

conductor, N – terminal for connecting the neutral conductor, L – terminal for connecting

the phase conductor).

green LED indicating the current AC supply status – ON when the AC supply is available

(correct operation of the power supply).

red LED indicating overload – comes on when the output current is equal to or higher

than 0.9 A.

Overload on the output can be signaled if too many devices are connected to the

powered KNX bus line. Reduce the number of connected devices and check if the

LED goes out.

red LED indicating restart of the KNX – comes on when the “Reset” button is pressed.

the “Reset” button allows you to restart the KNX bus. Press and hold down the button for

about 30 seconds to restart devices connected to the bus.

Pressing the “Reset” button restarts the power supply and the KNX bus. During the

restart, the bus line is deenergized and the power supply output shorted. All devices

connected to the bus line will be restarted.

4. Installation

Disconnect power before making any electrical connections.

The power supply unit should be installed indoors, in spaces with a normal air humidity, e.g.

in electrical rooms, on a DIN rail (35 mm).

1. Install the power supply on the mounting rail.

2. Use the connection terminal to connect the KNX bus cable to the power supply.

3. Connect the 230 V AC supply voltage to the connecting terminals as indicated on the

enclosure.

All connections should be made according to the diagram shown in the “Connection

diagram” section.
