General:General:General:General:

The series is a comprehensive collection of training aids, implemented in a modular form, which covers the range from the basics of electricity, up to circuit application of general electronics. The trainer consists of a collection of box-like modules, 100 x 160 x 20mm size, with a magnetic base and a printed circuit board front face. The PCB face includes the components and devices needed to perform the experiments with clear silk-screen printing indicating the component symbols, identities and interconnections. For the execution of the experiments the modules are placed on a metallic plate

(Base Plate, 430x310x30 mm) where they are retained by magnetic strips. The connections to the power supply and to the measuring instruments are by plug-in cables. Certain experiments require more than a single module to be interconnected. This is also done by plug-in cables. The magnetic latching of the modules to the metallic Base Plate ensures that the various items remain steadily fixed even if the Base Plate is placed vertically, as in case of collective demonstrations by the Instructor. A great variety of modules are available to cover in smooth steps the various subjects.
