COM3LAB - THE COMPACT ELECTRONICS LABORATORY
3 COMPONENTS BECOME ONE LABORATORY
COM3LAB is used for training and further education in electrical engineering and electronics and provides both theoretical and practical knowledge transfer from a single source. The subject matter is not only taught theoretically, but is also deepened by the use of practice-oriented experiments.
COM3LAB consists of a Master Unit and various courses - a course includes an experiment board and learning software. The Master Unit is the basic device via which the software and the experiment board communicate with one another. The COM3LAB learning environment combines experimentation with the advantages of interactive e-learning.
The new Master Unit is the bridge between the experiment board and the learning software. It contains all necessary measuring instruments and power supplies and possesses many significant improvements compared with its predecessors:
- Support for wired and wireless PC interfaces
- Luminous strip makes the system status display visible from a distance
- Anti-theft protection through Kensington lock
- Suitable for inclusive learning through two separate audio outputs
- Support for tablets 2 mm safety sockets and cables

ELECTROMOBILITY SYSTEMS ENGINEERING AND HIGH VOLTAGE TECHNOLOGY
THE ELECTRIC VEHICLE IN THE WORKSHOP
As vehicle electrics have largely been considered safe up until now, increased awareness of dangerous contact voltages and the targeted teaching of new safety measures and procedures are now required.
For this purpose, LD Didactic has developed a trainer on which trainees can practise the disconnection of electric vehicles in a manner similar to actual practice. The system has been designed to allow measurements to be carried out on both potential-free and live components. All measurements/exercises can be carried out without risk to the trainee and with no requirement for special protective equipment. For example, the disconnection of HV components under load as a learning situation can also be performed without risk, whereby it is still possible to see the impressive effect of the arcing when the high-voltage cable is cut.
- Integrated fault switch
- Construction of electrical networks
- Check HV voltage
- Criteria for the use of test devices
SENSORS AND ACTUATORS IN VEHICLES
AUTOMOTIVE PLUG-IN SYSTEM 2.0
Special vehicle sensors and actuators are mounted in or on plug-in elements to enable their fundamental functions to be easily investigated. The new option of colour printing on elements makes correct wiring more simple.
- Original components in transparent housings
- Very robust design Construction identical to circuit diagram
- Component symbols conform to
- ISO standard
- Surfaces printed in colour

RENEWABLE ENERGY TECHNOLOGY
ELWE Technik Wind Power Plant
With the "Wind Power Plant" experimental rig is an outstanding educational system of renewable energy generation. The student first acquires the basics of electrical power generation through exploitation of the kinetic energy existing in the wind. The student learns several common methods of connecting the asynchronous generator to the grid for channelling off energy.

ELECTRICAL MACHINE TRAINER - TAKE-APART MACHINES
With this teaching system, electrical machines for mains voltage (400 V) are constructed and investigated. The topics are very varied and range from the basics of magnetic electrical circuits to commutator machines and three-phase machines. All relevant components of the motors are visible and must be connected up mechanically and electrically.
The different types of machines can be fully characterized in experiments are measured and compared.
TAKE-APART MACHINES - INTERCHANGEABLE ROTORS
These new didactic machines consist of prefabricated industrial rotor and stator assemblies in the 300 W class. The ready-to-operate electrical machine emerges only after all components have been assembled.
The stator housing is mounted on a base and can be connected directly to the machine testing system 0.3 (731 989USB). The stator and rotor are connected securely using star grip bolts which allow a rapid change of the rotor. The rotors are equipped with a B-endplate, fanwheel, cover cap and, if required, slip-rings, brushes, etc.
- Comparison of the efficiencies and characteristic curves of machines with different rotors
- Simple assembly for short set-up times and time-effective laboratory experiments
- Comparison of aluminium rotors and high-efficiency rotors
MEASUREMENT AND CONTROL - CONTROL SYSTEMS AND CONTROLLERS
- Digital liquid control system
The liquid control system is a model system for measurement and control systems useful for both demonstration and student experiments. The liquid control system consists of a reservoir, a measuring tank and a pump, as well as sensors, valves and microprocessor-controlled electronics with an integrated power amplifier. The liquid control systems permits experiments to be performed on two independent technical processes:
- Flow rate
- Fill level

Compact controller 734 431
ELWE Technik - ASIMA
THE TRAINER FOR SPS AND LOGO
The tried and trusted trainer for programming electrical control systems has been revised. Owing to the large number of plant simulations, the trainer is able to give the trainee an understanding of the entire spectrum of control programming in small steps. Here it is an advantage that the simple plant simulations can be performed with either a small control system (LOGO from Siemens) or with a PLC. Three different packages are available for plant simulations as overlay mask sets for the ASIMA trainer.
In the case of ASIMA, the programming stands in the foreground, not the wiring. The wiring is carried out via a 50-pole cable, which makes it possible to connect the PLC directly to the ASIMA.

ELWE Technik - AMIRA
THREE TANK SYSTEM
The system consists of three Perspex cylinders. These are connected together in series via cylindrical connection channels. To simulate blockages or faulty operation, all connection channels, as well as the normal outflow channel, have manual valves that make it possible to close off particular channels.
To simulate a leak, each tank has a further circular opening with a manual
valve attached connecting, via a pipe, to the reservoir. Faults in ancillary components, such as pump defects, sensor failures, or poor scaling of sensor
signals, can be set on the control unit using potentiometers and switches.
