Abstract (en)
[origin: WO2010001057A2] The invention relates to a method for electrically securing an electrical power supply (1000) of an electrically controlled system with variable optical properties (100) positioned close to water. The electrically controlled system comprises a substrate (4, 5) carrying an electroactive element (3) disposed between first and second electrodes (1, 2) powered by a periodic voltage U(t) having a given maximum effective value U0 at a given low power supply frequency. The method consists of limiting the accessible potential at the input (1a) or output (1b) terminal of the electrically controlled system to a maximum value less than or equal to 50 V, said accessible potential being defined as the potential experienced by a human body in the event of contact with the input or output terminal. The invention also relates to the uses of the electrically controlled system thus secured.
