EL 9000 T Series
1.9 Construction and function
1.9.1 General description
The conventional, electronic DC loads of the EL 9000 T series with their small desktop enclosure in tower design
are especially suitable for research laboratories, test applications or educational.
Apart from basic functions of electronic loads, set point curves can be produced in the integrated function genera-
tor (sine, rectangular, triangular and other curve types). Arbitrary curves can be stored on and uploaded from a
USB stick.
For remote control using a PC or PLC the devices are provided as standard with USB, but can also be extended
by an Ethernet/LAN port as well as a fast and galvanically isolated analog interface by installing an optional inter-
face module.
All models are controlled by microprocessors. These enable an exact and fast measurement and display of actual
values.
