Intrinsically safe power supply with a current regulator

摘要: An intrinsically safe power supply arrangement with a current regulator is provided controlled semiconductor, coupled to clock generator and between rectifier primary winding of transformer, for periodically interrupting DC in response signal. A short-circuit switch disposed secondary the transformer an output arrangement. choke switch, voltage limiter choke. regulator, arrangement, has retrogressive current-voltage characteristic delay stage producing time-delayed rise selectable combination voltage. circuit element supplies input signal regulator. generator. measuring limits supplied event on side transformer.
