Title: METHOD FOR IDENTIFYING THE TYPE OF SUPPLY VOLTAGE SUPPLIED TO AN OPERATING DEVICE FOR LIGHTING MEANS
Abstract:
The invention relates to a method for identifying the application of a sufficient input-side supply voltage to an operating device (10). A supply voltage (Vmains) supplied to an operating device (50) is rectified and subsequently compared with at least one first reference voltage (Vref1). The application of a sufficient input-side supply voltage is determined if the rectified supply voltage exceeds the reference voltage for a specified period of time, wherein additionally the peak value of the supplied supply voltage (Vmains) or of the rectified supply voltage is also detected, and the application of a sufficient input-side supply voltage is determined only if the peak value satisfies a specified condition, in particular exceeds an additional specified reference value.
