7 Equipment Description Workstation The workstation allows two student groups to work simultaneously. The structure is pre-assembled, made of steel, and intended for use on a table (not supplied, offered as option). Four pairs of mounting rails firmly hold the modules of the HVAC-R line of products in place. One holder on each side permits users to neatly arrange the test leads. A touch-screen computer mount (not supplied, offered as option) can be attached to either side. Available Space Intended Location Power Source Provides enough space for two student teams, one on each side. On a table able to support the weight of the equipment The Power Source provides power to the other modules of the training system through 4 mm terminals. The module can be powered via standard single-phase ac power outlets. The power source output voltage is equal to the voltage of the ac power network to which the power source is connected. A thermal-magnetic circuit breaker provides overcurrent and short-circuit protection. Festo Didactic 7
