#CMT# #/CMT# The method involves rectifying an available voltage, such that the available voltage is divided into a positive and a negative voltage component. The two voltage components are applied as voltage sources for two measuring circuits (M1,M2). The current in the two measuring circuits are evaluated for identifying the type of the available voltage. The current in the measuring circuits are affected, such that the intensity of current in the two measuring circuits is different. #CMT# : #/CMT# An independent claim is included for a circuit for identifying the type of a voltage, particularly an operating voltage supplied to an operating device for an emergency light. #CMT#USE : #/CMT# Method for identifying the type of a voltage, particularly an operating voltage supplied to an operating device for an emergency light. #CMT#ADVANTAGE : #/CMT# The current in the two measuring circuits are evaluated for identifying the type of the available voltage, and the current in the measuring circuits are affected, such that the intensity of current in the two measuring circuits are different, and thus enables an easy and accurate determination of the operating voltage type. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram for identifying the type of operating voltage supplied to an operating device for an emergency light.
