Operating the device
6.3 Overtemperature
If the unlikely event of an overtemperature (OT) error oc-
curs by internal overheating, the output voltage is cut off
and the status token „OT“ is shown in the display, together
with the text „Error“. The output will automatically switch
on again after the unit has cooled down. In case this is not
wanted, the output can be manually switched off during the
overtemperature period.
6.4 Overcurrent
The device can react in two different ways to overload
resp. overcurrent:
1. By switching the output off (OCP) or
2. By limitting the output current (CC)
In order to switch the output off, it is required to adjust
the OCP value (see section 5.4) to lower than the current
limitation or constant current set value I
the current is just limited.

7.1 Hardware problems
Problem: After switching the device on nothing happens
Reason(s): Input fuse broken, other defect
Solution: If the display remains dark, check the input fuse.
It is located inside the input socket on the rear, in a little
„drawer“. It can be checked visually or by means of a mul-
timeter. If the fuse is broken, replace with same type and
value and try again. If the error remains, contact your sup-
plier. In such a case the unit is usually returned for repair.
Problem: The display only shows „PS 2000“ after switching
the device on
Reason: An error occured during a firmware update
Solutions: Switch off device and on again, if this does not
help, try to repeat the firmware update procedure.

8.1 Series connection
Several units of preferrably same type, but at least with
identical nominal current, can be connected in series in
order to gain a higher total output voltage.
To do so, the positive DC output of one unit is connected
to the negative DC output of the next unit etc. The pos. DC
output of the last unit will then be the positive output of the
whole series connection and will have the high potential.

lowed to connect an arbitrary number of unit in series.The
maximum allowed total voltage of serially connected units
is 600V. For a series connection with such high voltage
extra measures for safety have to be taken.
Because of safety and insulation reasons it is not al-

mine the maximum current of the system.

the desired output voltage can not be achieved anymore.

DC output of the first unit (the one with the lowest potential)
may be grounded.
8.2 Parallel connection
Several units of preferrably same type, but at least identical
nominal output voltage, can be connected in parallel in
order to gain a higher total output current.
Every unit has to be adjusted seperately (manually or
remotely by a PC). It is recommended to adjust the output
current to the maximum and the output voltage to identical
values on every unit.

nected in parallel and the unit with the lowest nominal
current changes into current limitation it will drop its output
voltage and will thus not be available anymore as current
source in the parallel system, unless the output current is
sinking again below the limit.
8.3 Remote control
The device can be remotely controlled via the USB port
by means of a PC and a Windows software called Ea-
syPS2000. The software and a USB cable are included in
a seperately available kit. The device requires a license
code to be unlocked in the software. The code can be
purchased as an option. Further information are available
upon request or in the user guide of the EasyPS2000 soft-
ware, as well as on our website. In order to purchase the
kit and the license code, contact your dealer or send an
e-mail to
number and serial number of the device.
8.4 Firmware udpates
The device firmware can be updated if necessary. Details
about firmware updates and the procedure can be found
in the user guide of the software EasyPS2000, which can
be found in the seperately available software kit or on our
website. Only this software can be used to update a PS
2000 B unit.
