The power supply 2x320 REG-K makes the energy
available for the bus devices on two lines. The device
has two integrated chokes which isolate the data tele-
grams from the power supply. The bus voltage can be
picked up via a bus connecting terminal. A data rail is
not required. The power supply (PS) provides a stabi-
lised safety extra-low voltage (SELV) of DC 29 V ± 1 V.
The max. output current is 320 mA per line.
If the bus devices are evenly distributed on the line, it
is possible to operate up to 64 bus devices on one line.
The max. cable length between the power supply and
the furthest bus device is 350 m.
Two slide switches are located under the hinged cover
next to the bus connecting terminals. In the "RESET"
position, the connected bus devices for each line are
reset. This state is indicated by a red LED (RESET) on
the device.
|The disconnection of a line (RESET) should be
retained for at least 30 seconds.
The bus votlage is connected by setting the slide
switches to the "ON" position. The green LED (RUN) in-
dicates that the power supply is ready for operation.
If the output current is too high, the red overcurrent
LEDs (I>Imax) light up or flash. In the event of a short cir-
cuit between the red and black conductors of the bus
cable, the green LEDs (RUN) are extinguished or flash.
|Once the short circuit has been rectified, the
power supply must be switched to the "RESET"
state for approx. 5 seconds.
Meaning of the LEDs
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
