Conducted control method for emergency lighting system during building installation, involves providing null value detector in receiver so that valid switching information is produced to detect phase sections as faulty information

摘要

The method involves forming a distribution network to an end electric circuit using a power supply line. A short-circuit load and a MOSFET between the line and energetic reflow lines are formed during current supply disconnection to the circuit. A null value detector for a supply voltage (43) is provided in a receiver so that the valid switching information is produced by switching off in a zero point of a shift signal-moderate power supply and switching of a power supply in a null point (69) of an alternating current voltage (47) to detect phase sections as faulty switching information. An independent claim is also included for a safety power supply system having a control unit and a power distributor.
