Abstract

Device for the regulation of electrical supply voltage to electric-discharge lamps, comprising: a) an autotransformer, endowed with: an input section connected to the mains supply an output section, b) a power circuit inserted between the transformer output and the electric-discharge lamps, c) a control circuit regulating the power circuit. The former basically consists of: i) a measurement circuit connected to the mains, ii) a threshold circuit connected after the measurement circuit, iii) a command circuit, connected after the threshold circuit, regulating the power circuit. <IMAGE>
