The elneos® six device groups at a glance

Discover the newly developed "elneos six" laboratory devices, which have been improved in many details. The device system has been significantly expanded and offers an enormous range of new possibilities.

Precision Control Units

The control units are a comprehensive innovation with the highest demands on accuracy, dynamics and quality. A powerful, proprietary microprocessor system on the control card enables autonomous operation, independent of the main processor system of the control center. This is a real-time system. The instrument's new control card has outstanding dynamics, which can be used to generate powerful arbitrary signals up to the kHz range.

Flexible screen layout allows up to 4 power supplies to be operated simultaneously. Optional components like rotary encoder or wheel increase the input comfort.

Power arbitrary generator 2,5 kHz

A table allows the input of all waveforms and parameters. The evaluation of the curves is visualized by the data logger with recording function. Due to the powerful processor, several power arbitrary generators can process and display different sequences simultaneously.

Up to five measurement curves can be visualized simultaneously. Likewise, values from other devices can be recorded and displayed in parallel. Results can be quickly documented with the graphical display. The data logger, which works in the background, stores the data that can be read out later. The dynamic range of the new measuring card allows the simulation of almost all signal shapes. Vehicle voltage pulses, high-energy bursts, sudden voltage dips and many more can be quickly simulated.

Power and energy meters

The power and energy meters enable the acquisition of high power and energy for 1-phase loads up to 24 kW with exceptional accuracy. A digital output can be set if limit values are exceeded. If necessary, an external circuit can react to dangerous situations and deactivate the respective periphery. The power is acquired via the front-side laboratory sockets of the digital multimeter. This means that no additional connections are required.

The integrated new measurement technology of the device thus provides an enormous bandwidth. The power meter is integrated directly behind the lab jacks to save space and thus does not require a separate slot on the internal backplane. This means that even more additional devices can be integrated in a very small space.

Switch Mode Power Supply

The new DC power supplies contain high-quality AC/DC converters. The compact design allows full integration into the modern elneos six control center. 1 to 1,500 watts of power can thus be offered as compact stand-alone devices. Integrated fans ensure permanently high performance in this power class.

The encapsulated power modules of the power supply units are also characterized by the fact that they can be integrated into the control center in the 800 W and 1,500 W sizes. Only the 3,000 W power module has to be integrated outside the control center in the device cockpit, in the table superstructure or in the TechCube below the table surface.

Precision digital multimeter

The 5 3⁄4-digit precision digital multimeter already allows the acquisition of currents up to 40 A and voltages up to 1000 V in the basic version. An optional simultaneous acquisition of current and voltage AC/DC saves the user a 2nd digital multimeter.

Optional measurement amplifiers allow high current measurements up to 125 A, which significantly extends the application range of the instrument. An integrated diode test, capacitance measurements as well as temperature and frequency measurements and the graphic display of the current and stored measured values make the multimeter an all-rounder.

Dual function generator

The device contains two function generators and uses the operating principle of direct digital synthesis (DDS) with the associated advantages of frequency-stable and low-distortion signal generation. The first function generator serves as the basic function generator and feeds its signals to the outside. The second function generator is used exclusively for modulation. Its signals are modulated with the signals corresponding to the selected modulation type of the first function generator.

The maximum output frequency up to 40 MHz as well as the amplitude level with 30 Vpp idle are outstanding. In combination with an adjustable duty cycle from 0.1 to 99.9%, elneos six is an all-rounder. Many functions such as sweep, an external and internal trigger for defined start conditions, programmable single and multiple pulses and many more make the function generator an all-rounder.

All parameters of the carrier signals and the useful signals (modulation signal) such as waveforms (sine, square, triangle, etc.), amplitude, frequency, duty cycle are stored separately and modulated at the output. The depth of the modulation can be set from 0 to 100 %. With the freely programmable modulation, elneos® six offers a productive tool for education and industry with a direct positive effect in the application.

Dual signal arbitrary generator

The additional arbitrary function allows to generate arbitrary waveforms besides the standard waveforms. For the generation of the signals, 8,192 sample points are available for two curves. Two waveforms can be stored and recalled. Using the highlink Power remote control software, waveforms can be generated in graphical or tabular form on the PC and transferred to the instrument.

If this fast arbitrary function generator is combined with the power arbitrary generator for high electrical output signals of the control power supplies, all conceivable simulations, tests and measurements of power electronics and fast signal electronics can be carried out with a single device. If, in addition, the powerful digital multimeter with power meter and one of the new AC sources are selected, a complete measuring station can be replaced with a single measuring device.

AC voltage sources

The AC device program includes extensive models for 1- and 3-phase AC power supply incl. ramp function and rectifier. The compact devices are installed in a separate 19-inch subrack, depending on the power and device equipment.

The control center communicates directly with the respective AC source via the e-bus, so up to seven AC sources can be controlled simultaneously. For single-phase devices, a choice can be made between electromechanical AC sources and electronic AC sources. The electronic AC sources allow variable frequency adjustment up to 400 Hz.

Data logger

The data logger with its graphical and tabular recording function is already part of the standard equipment of every control power supply unit, power arbitrary generator, digital multimeter, power meter and all AC sources. The data logger has a storage volume for measurement data of up to 500,000 measurement points, i.e. 5 measurement curves of 100,000 measurement points each can be stored. It offers a high-speed mode of up to 1/100 sec. resolution. An alphanumeric display keyboard allows a meaningful name assignment. The stored files can be loaded, exported or deleted at any time. Alternatively, the internal memory can be read out via LAN, USB, WLAN and BT. The measurement data is transferred to all end devices immediately.

Due to the high sampling rate of the data logger (0.01sec.) and the high display resolution of the new 8" multi-touch display of 800 x 1200 pixels, the measurement data can be displayed in very good quality. In the screen display "2/3-Screen" and "Fullscreen", a permanent graph is displayed parallel to the respective adjustable device parameters. Even in the small "Quattro-Screen" the graphical and tabular value display can be selected, zoomed and scrolled.
