The issue of introducing energy-saving technologies into the light, especially in the context of a continuous increasing the electricity cost, is topical and can significantly reduce energy consumption. The power consumption for lighting can be significantly reduced by achieving the optimal operation of the lighting unit at any time. To achieve the most complete and accurate number of the daylight, as well as the number of people, can be made by means of automatic lighting control. The operation principle of these devices is based on full or partial off of the lighting load when the natural lighting of a given level is exceeded. Automatic control of lighting can reduce the current power of lighting, as well as exclude the possibility of lighting during nonworking hours behind the guiding signals. Nowdays, a large range of automatic control tools has been developed and applied in various national economy sectors. At the same time, the experience of using these devices showed that in the conditions of sharply variable traction loads there are malfunctions in the work, due to insufficiently stable operation of power units. Therefore, there was an analysis of voltage quality supplying the light automats, it was also provided the modernization of power sources for switcher of MAK series to ensure reliable and uninterrupted operation under conditions of significant fluctuations in the power supply on the railway.
