Abstract

Electronic unit for magnetising and demagnetising electropermanent appliances, essentially characterised in having a compact assembly, equipped with central control unit, arranged on an independent printed circuit with the CPU, an EPROM memory unit and a RAM memory unit, a general power supply formed by three sections and one additional filter, a power supply source consisting of a toroidal transformer, a bridge rectifier, and a capacitor, a regulation of load formed by one or more capacitors, including a current limiting unit, and situated between the load unit and the selector of plates to be demagnetised or magnetised, a current inverter, formed by two contactors and one thyristor or by a bridge of thyristors, the assembly being completed with peripheral elements for data multiplexing, optional display, controls and light indicators, all of this applicable to machine tools, cranes, or whatever else utilises electropermanent apparatus in its functioning.
