6. Other applications
6.1 Series connection of outputs 1 & 2
The main outputs 1 and 2 can be connected in series in
order to gain a higher output voltage. Following applies:
• There will be no totals formation of the total output voltage
on any display
• The total voltage is the sum of the single output voltages
• The maximum current is limited to the lowest adjusted
current of both outputs. It means, if one output is set to
0A, the unit will not put out voltage and no current during
series connection
It is recommended to use tracking mode (see 4.6), in order
to have the adjusted voltage and current at identical values.
 Series connection of any or both outputs 1 and 2 with
output 3 is allowed.
6.2 Series connection of several units
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.
 Because of safety and insulation reasons it is not al-
lowed to connect an arbitrary number of unit in series. The
DC minus pole (black) of any output on any unit must not
have a potential of higher than 300V DC against ground
The maximum allowed series connection voltage is 342V
DC for 42V models and 384V DC for 84V models. Special
safety measures are required when working with such
high voltages!
 If units with different nominal current are connected in
series, the unit with the lowest nominal current will deter-
mine the maximum current of the system.
 In a series connection, only the positive or negative
DC output of the rst unit (the one with the lowest potential)
may be grounded.
6.3 Parallel connection of outputs 1 & 2
The main outputs 1 and 2 can be connected in parallel in
order to gain a higher output current. Following applies:
• There will be no totals formation of the total output current
on any display
• The total current builds from the output current of the
single outputs
It is recommended to use tracking mode (see ), in order to
have the adjusted voltage and current at identical values.
 In parallel connection of the main outputs 1 and 2, the
output voltage of one output can cause an OV error on the
other output. See section 5.2 for details.
Operating the device
6.4 Parallel connection of several units
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.
 If units with different nominal output current are con-
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 voltage
source in the parallel system, unless the output current is
sinking again below the limit.
6.5 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 software requires a license
code to unlock the device in the software. The code can
be purchased as an option. Further information is 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 [e-mail] and state article
number and serial number of the device.
Alternatively, the device can be controlled remotely by
custom software. There is documentation about the com-
munication protocol available upon request, together with
the USB driver (Windows only). Example code or LabView
VIs are not available.
