About the device
1. Introduction
The electronic loads of the series EL9000HP are very
efficient devices which offer a big variety of interesting
features in a 19“ case of 9 U. Besides the common func-
tionality of electronic loads you can test batteries, load
voltage or current sources with a pulsed operation, where
the pulse widths and the amplitude are adjustable. Or
you can remotely control the device via an interface card
and control and monitor nearly all its features from a PC.
The integration into existing systems is made easy by
using one of the interface cards, the configuration is
intuitive and is done at the device. The electronic loads
can thus be operated in conjunction with a power supply
of the series PS9000/PSI9000 or, with the additional
analogue interface socket at the rear side, controlled and
monitored by any other device with an analogue interface.
The device is microprocessor controlled. This results in
an accurate and fast measurement and display of actual
values, as well as an extended operability by many new
features which wouldn‘t be realisable with standard ana-
logue technology.
The modern design offers highest performance and
enables space-saving conceptioning of complex and
efficient applications, like for example industrial test
equipment with variable powers for different demands
or for demonstration and test purposes in the research
and development area.
The digital control and the retrofittable interface card
strongly simplify the connection to professional, industrial
bus systems like CAN. Nearly all possibilities of the single
systems are used. With USB you can plug and use up to
four (or more) devices to a standard PC without the need
of additional hardware. At CAN you can implement the
devices into existing CAN bus systems without the need
to reconfigure the whole bus system. Address range and
transmissions speed can be selected for the particular
EL9000 HP unit, so it fits best.
The main functions at a glance:
•
Set U, I, P and R, each 0...100%
•
Battery test with Ah and time count
•
Pluggable interface cards (CAN, USB, RS232, IEEE/
GPIB, Ethernet/LAN)
•
Analogue interface for external control
•
Pulsed operation between two set values with adjustab-
le pulse widths and adjustable rise/fall time
•
Adjustable duty cycle (as time) of 50µs...100s and
adjustable rise time of 30µs...200ms
2. Technical specifications
2.1 Control panel
Type
Display:
two line character LCD with
80 characters
Operating elements: 2 rotary knobs, 2 rotary
switches, 1 pushbutton
Display formats
The nominal values determine the adjustable range.
Actual and set values are displayed all at once, as long
as the currently active operation mode allows it.
Display of voltage values
Resolution:
4 digits
Formats:
0.0V…999.V
Display of current values
Resolution:
4 digits
Formats:
0.00A…99.99A
Display of power values
Resolution:
4 digits
Formats:
0.0W…999.9W
Display of resistance values
Resolution:
4 digits
Formats:
0.00Ω…99.99Ω
0.0Ω...999.9Ω
Display of time
The elapsed time (only battery test mode) is display in
the format Hours:Minutes:Seconds (HH:MM:SS).
Resolution:
1s
Range:
1s...99h:59m:59s (99:59:59)
This time stamp can be read out via one of the pluggable
interface cards, together with the pulse widths and rise
time of the dynamic Level A/B operation. The dynamic
values can also be set remotely. In order to do so, the
time format has been extended so it can represent 1µs
up to some years.
Detailed information about this can be found in the in-
struction manual of the interface cards.
