Electrical Transformer Trainer

Model: CET-301

Brand: CHOIEO

C/O: China

 

  • This trainer is designed to meet the operation training of electrical transformer, covering a variety of training topics for single-phase and three-phase characteristics, as well as parametric measurement.
  • The frame adopts a standard aluminum profile with a modular experiment panel design, thus, making it easy to build different experiment combinations on the flexible two-layer structure. All the upper parts are removable including the experiment module, power supply module, and frame support.
  • All terminals are led out on a printed composite panel with a 4mm safety socket and connected by full sealing sheathed pluggable connector. The complete unit is movable with lockable truckles on the bottom and available for training content extension by using other CHOIEO modular electrical units.
