| • This trainer is designed to meet the
operation training of electrical transformer, covering a variety |
| training topics for single phase and
three phase characteristics, as well as parametric measurement. |
| • The frame adopts standard aluminum
profile with modular experiment panel design, thus, making it |
| easily to build different experiment
combination 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 printed
composite panel with 4mm safety socket and connected by |
| full sealing sheathed pluggable
connector. The complete unit is movable with lockable truckles on |
| bottom and available for training
content extension by using other CHOIEO modular electrical units. |
