Description

The EDU-LABS EM-68280Q system consists of a series of modular slot-in panels modules housed in a compact epoxy coated casing. Each modules represents one or more electrical / electronic components or on block diagram of a complex circuits. All functional parts of the components are mounted inside the modules with circuit symbols/mimic diagrams screen printed on the front PCB panel and terminated at 4mm safety sockets for student experimental practice.

The machines are basically industrial models, self protect kind, with coupling half-joint, especially equipped to be suitable for student training in laboratory. For this purpose the winding ends are connected to 4 mm safety socket in a metal housing on top of which a clear synoptic diagrams as educational terminal board. The student can easily understand operation and winding connection. Also most of accessories and instruments designed in Panel System A4 high in standard.

All modular slot-in panels modules are inter connecting together by using 19mm short circuit shunt and / or 4mm stackable safety test leads sets to form the desired control circuits.
