ET 170 Domestic Air Conditioning Controls Show data sheet (pdf file)
Technical Description
The ET 170 unit facilitates the investigation of electrical components used in air conditioning. This includes fault simulation and faultfinding on a compressor and fan motor. These devices are simulated with this unit. During this process the switch state of the equipment is indicated by signal lamps that are arranged on the display and control panel. The related starting, safety and control devices are also clearly laid on the front panel. Laboratory sockets facilitate access to measured points in the electrical circuit. The simulation of 15 faults that can be enabled via the electrical system is performed using push buttons. The ET 170 series was designed primarily for training on refrigeration and air conditioning systems and is particularly suitable for use in small student groups.
