FUNCTIONAL DESCRIPTION
The following block diagram gives information about the various adjustment options.
Basically, four different operation modes are available:
UI mode
Unit is operated with current and voltage limitation.
UIP mode
Unit is operated with current, voltage and power limitation.
UIR mode
Unit is operated with current, voltage and power limitation. Additionally, the set value for
voltage is calculated by means of the present output current to simulate an internal
resistance.
Table mode
Set values for current and voltage are saved in a table. Therefore, UI characteristics can be
easily adjusted.
There are three different ways to program the table:
PV
sim
mode
The UI characteristic of a solar generator is calculated with the Uo, Ik, Umpp and Impp
parameters and then written to the table.
Memory card
The table can be programmed using a script from a memory card.
A script is a simple text file (
Script Control ).
Digital interface
The table can be programmed using the digital interface ( Universal Interface , WAVE
Command
bzw.
DAT Command
).
