The principle of autoranging

This description should clarify the availability the voltage

and current ranges within the power hyperbole.

Function generator

All models in the ELR 10000 series are equipped with a func-

tion generator. This allows curve processes such as sine,

triangle, square or trapeze to be simply called up. A ramp

function and a arbitrary generator allow voltage and current

progression to be freely programmable. Test sequences for

repeated tests can be saved and reloaded when needed,

that´s saving time. A LUT allows IU and UI reference lines

to be stored. For simulation of a photovoltaic system or fuel

cells, adaptable tables are provided. With the standard PV

characteristic curve (DIN EN 50530) various solar cells and

many other technology parameters can be selected and

set. In short, the user is supported by a multitude of useful

functions.

Interfaces

As standard EA devices are tted with the most important

digital and analogue interfaces and ports which are galva-

nically isolated. These include an analogue interface which

can be parameterised for input and output, control and mo-

nitoring, of 0 - 5 V or 0 - 10 V for voltage, current, power and

resistance, assorted inputs and outputs as well as USB and

ethernet ports. The following options which use a Plug &

Play slot, complete the portfolio:

- CAN

- CANopen

- RS232

- Profibus

- EtherCAT

- Profinet, with one or two ports

- Modbus, with one or two ports

- Ethernet, with one or two ports

DC Input

The input of the electronic load ELR 10000 with a DC volta-

ge of 0 - 80 V up to 0 - 2000 V allows currents of 0 - 6 A up

to 0 - 1000 A. The exible input stages (autoranging) provi-

de the user with a wide voltage, current and power range

and hence a wider eld of working than traditional power

supplies.

DC Connection

Connection of the DC output is via a copper rail on the back

side of the device. If a system with higher performance is

required, the devices are simply connected in parallel. With

minimal effort devices can be linked with the vertical cop-

per rails. A cover for contact protection is provided.
