The power supply makes the energy available for the
bus devices on a line. At least one power supply is re-
quired per bus line.
The power supply (PS) provides a stabilised safety ex-
tra-low voltage (SELV) of DC 29 V ± 1 V. The max. out-
put current is 160 mA. If the bus devices are evenly
distributed on the line, it is possible to operate up to 32
bus devices on a line with the standard power con-
sumption of 5 mA. The max. cable length between the
power supply and the furthest bus device is 350 m.
The bus devices on the connected line can be reset via
a slide switch on the power supply (under the hinged
cover next to the bus terminal). The state (RESET) is in-
dicated via the red LED (RESET) on the device.
|The disconnection of a line (RESET) should be
carried out for at least 30 seconds.
The bus voltage is connected by setting the slide
switch to the "ON" position. The green LED (RUN) indi-
cates that the power supply is ready for operation.
If the output current is too high, the red overcurrent
LED (I>Imax) lights up or flashes. In the event of a short
circuit between the red and black conductors of the
bus cable, the green LED (RUN) is extinguished or flas-
hes.
|Once the short circuit has been rectified, the po-
wer supply must be switched to the RESET sta-
te for approx. 5 seconds.

Power supply 160 REG-K
Art. no. 683329
The INSTABUS power supply is mounted on a DIN rail
EN 50022-35. A data rail is not required. The bus con-
nection is carried out via the bus connecting terminal
supplied with the device. The cable cover is then
placed over the bus connecting terminal to guarantee
the safety clearance of the bus cable to the 230 V ca-
bles. A maximum of 4 core pairs can be connected to
a bus connecting terminal. All the devices that are
mounted next to the power supply must at least be
equipped with basic insulation.
Connection of the power supply REG-K
The mains voltage connection is carried out via plug-in
terminals with screw connection. The cables can be
screwed onto the plug-in terminal before installing the
device and then inserted at a later date.
