Lighting and Device


Technology

The exercise boards have been designed for practical exercises in installation techniques, at a student workplace. The clear arrangement of components follows the presentation in the appropriate training manual. All inputs and outputs for mains voltage (230V) are terminated at 4mm safety-protected sockets. All voltages <42V (safety extra low voltage, SELV) employ 2mm safety techniques. The compact construction means that any classroom can be very quickly and easily be converted to a fully-functional laboratory. There are no problems in integrating the boards in the LN teaching equipment program, so that individual exercises can easily be extended as required.
