3.2.25. Analog programming input
The Electronic Load has an analog programming input on the rear panel of the
mainframe. The analogue programming input enables the load module to track and
load according to an external 0-10V (ac or ac + dc) signal.
The analog programming input is configured as a BNC socket on the mainframe's
rear panel.
The analogue programming input operates in CC or CP modes only. The 34000A
series Load will attempt to load proportionally according to the signal and the load
module's maximum current or power range. For example: 34210A: Imax = 320A
and Pmax = 10000W
So in CC mode if analogue programming input is 5V = 160A load setting (Range II)
Or in CP mode if analogue programming input is 1V = 1000W load setting (Range II)
The analog programming signal can act
alone or it can be summed with the
programmed value set via the front
panel or the optional computer interface
(GPIB, RS-232, USB, or LAN) or the
front panel.
Example:
Fig 3-6 shows the result of an analog
programming signal at 4 Vac, 500Hz
when it is summed with a 128A
programmed setting in CC mode of
34210A Load.
