Technical Description
The unit was designed for training on refrigeration engineering. Electrical starting, operating, and control units as are necessary for the safe operation of a refrigeration system are demonstrated. Typical power and control circuits can be demonstrated and wired up on the clearly laid out benchtop unit. The industrial components provide students with a relevant practical education.
Learning Objectives / Experiments

Topics include:

- Limiting starting current

- Starting and running capacitor

- star-delta configuration

- Wiring diagrams for electrical components

- Direction of rotation change in the AC circuit

- Thermostats

- Motor protection devices

- Layout of safety interlocks
Features
