It is standard practice to provide controlled temperature and humidity in testing and calibration laboratories. But it is equally important to provide a stable supply voltage both to the equipment under test and to the testing instrumentation.
Specifications for the testing of many types of equipment and apparatus require the application of a specified supply voltage and it is often required that tests are carried out over a range of voltages.
Feeding a variable test voltage provided by Claude Lyons Regavolt® Variable Transformers, from a stabilised mains supply ensures repeatability and adherence to specifications. Manufacturers and importers of power domestic machines have found this especially beneficial.
