KNX power supply 640 mA 2002 REG
ETS-product family: System components
Product type: Power supply
Series embodiment (SE)-device (7 units)
The power supply 640 mA produces and controls the system power for two or three bus lines for an KNX system.
The devices can be connected to two independent bus lines via the terminal BUS 1 and BUS 2, without an additional choke.
Furthermore, the power supply offers a 30 V DC output to supply a further bus line (i.e. main line). For this an additional choke is required.
Alternatively, that output can be used as a power supply for any further low voltage equipment.
The connection of the bus by a bus terminal on the device does not require any data rail. According to the KNX regulations it is possible to connect
the two outputs in parallel, when there is a minimum distance of 200 m between the bus terminals.
The distribution of the load (KNX devices) is flexible on all outputs, but the rated current of 640 mA is the total limit.
There are two reset switches on the device to short-circuit both bus lines separately. The operation time for a reset should be at least 20 sec.
Five LED´s are indicating the different operation status:
LED-indication: 1st red LED: short-circuit or overload
green LED: normal operation
yellow LED: over voltage, when bus voltage > 31 V DC
2nd red LED: reset 1 for bus line 1
3rd red LED: reset 2 for bus line 2
