Additionally to the standard functions, which are all based upon a so-called arbitrary generator, this gen-
erator is accessible for the creation and execution of complex sets of function runs, separated into up to
99 sequence points. Those can be used for testing purposes in development and production. The sequence
points can be loaded from and saved to a standard USB stick via the USB port on the front panel, making it
easy to change between dierent test sequences.

There is furthermore an XY generator, which is used to generate functions such as IU, dened by the user
in form of tables (CSV le) and then loaded from USB stick. For photovoltaics related tests, a standard PV
curve can be generated and run from user-adjustable key parameters, including an extended version ac-
cording to the european norm EN 50530.
Master-slave
All models feature a digital master-slave bus by default. It can be used to connect up to 32 units of identical
models in parallel operation to a bigger system with totals formation of the actual value of voltage, current
and power. The conguration of the master-slave system is either completely done on the control panels
of the units or by remote control via any of digital communication interfaces. Handling of the master unit
is possibly by manual or remote control (any interface).
Analog interface
There is a galvanically isolated analog interface terminal, located on the rear
of the device. It oers analog inputs to set voltage, current, power and re-
sistance from 0...100% through control voltages of 0 V...10 V or 0 V...5 V. To
monitor the output voltage and current, there are analog outputs with 0
V...10 V or 0 V...5 V. Also, several inputs and outputs are available for con-
trolling and monitoring the device status.
Control software
Included with the devices is a control software for Windows PCs, which al-
lows for the remote control of multiple identical or even dierent types of
devices. It has a clear interface for all set and actual values, a direct input
mode for SCPI and ModBus RTU commands, a rmware update feature and
the semi-automatic table control named “Sequencing”. Further features
which can be unlocked by a purchasable license:
Graphical visualization of the actual values
Multi Control - an app to control up to 20 units at once, including Sequenc-
ing and Function Generator
Function generator control with simple PV, PV EN 50530, Sandia and SAS
Options
Digital interface modules for RS232, CAN, CANopen, ModBus TCP, Profibus, Profinet, EtherCAT or Ether-
net. The interface slot is located on the rear panel (standard models only), making it easy for the user to
plug in a new interface or to replace an existing one. The interface will be automatically detected by the
device and requires no or only little configuration.
Three-way interface (3W) with a rigid GPIB port installed instead of the default slot for retrofittable in-
terface modules
Programmable bidirectional DC power supplies
