ELECTRICAL MACHINE TRAINER

The Standard Lab has been designed for experimental and testing in electrical machines in education. 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. The machines powers are 350W and 750W selectable, as the supply requirement for the system operation requires 240/415V, 50Hz.

• Modularized design providing the most flexible requirement of this experimental equipment. 
• Each Module panel height compatible with DIN A4 standard.
