The PLI series of electronic loads provide a comfortable operation by a graphical user interface. The PLI series highlight is the extensive variety of standard interfaces. Apart from Ethernet, USB, RS-232 and Analog interface there is a standard CAN interface. Programming is done in SCPI syntax.
The units provide constant current mode, constant voltage mode, constant power mode and constant resistance mode.
In addition, protections for current and voltage can be set in any mode.
A static data acquisition function allows to store measurement data on an external USB flash drive.
Dynamic operation can be configured by up to 300 list point settings. The Electronic Load saves the synchronously acquired measurement data with timestamp.
A configurable trigger model controls data acquisition, static and dynamic settings.
Energy Storage Test/Discharge Function
An implemented test function enables discharging energy storages such as accumulators, batteries, ultracaps etc. in an easy way and supplying determined values like charge and energy.
Internal Resistance Measurement
Measurement of the internal DC resistance of energy storage systems such as batteries, accumulators, capacitors, as well as cables, power supplies and so on.
When the watchdog function is activated, the load input is switched off in the event of a faulty communication with the control PC in order to protect the connected test item.
MPP Tracking (Optional)
The Electronic Load automatically searches for the Maximum Power Point of solar panels and self-adjusts as the sun's radiation changes.
The model range covers power classes from 600 W, up to 28,000 W continuous power rating.In addition the models up to 300 V have an overload capability. The height and duration of the possible overload depends on the temperature of the power stage. The unit indicates the currently possible overload. Therefore the units can be used even for considerably more powerful applications.

LabVIEW drivers are certified by National Instruments.
Analog I/O Port
The standard Analog I/O Port provides the following functions:
• Load setting C and V
• Analog setting the C and V protections
• Load on-off
• Voltage monitor output
• Current monitor output
• Trigger input
• Trigger output

Galvanically isolated Analog I/O Port
For the galvanic isolation between the Analog I/O Port and the load terminals the PLI06 option can be installed.
Using this board also prevents ground loops.
Factory Calibration Certificate
A free Factory Calibration Certificate (FCC) is supplied with the devices. The FCC meets the requirements according to DIN EN ISO 9000ff. This calibration certificate documents the traceability to national standards to illustrate the physical device in accordance with the international System of Units (SI). Within the warranty period we calibrate a second time for free.
The recommended calibration interval is 2 years.
We supply a User Manual as pdf file and printed General Safety Instructions, each in German and English.
