Carlo Gavazzi A74-105 is a three-phase AC current transformer for measuring currents up to 5 A AC and providing a proportional 0.4–2.83 V analogue output for industrial current monitoring applications.
£165.93
The Carlo Gavazzi A74-105 is a compact three-phase AC current transformer designed for reliable current measurement in industrial automation, motor monitoring and electrical control applications. As part of the Carlo Gavazzi A74 Series, it provides an isolated analogue voltage signal proportional to the AC current passing through the monitored conductors.
Designed for an input measuring range of up to 5 A AC, the A74-105 provides a proportional analogue output for connection to compatible current monitoring and control equipment. Its three-phase construction allows multiple phase conductors to be monitored through a single compact device, making it particularly useful for three-phase motors and industrial electrical loads.
The A74-105 features an analogue output specified at 0.4–2.83 V, with the A74 Series commonly described by its corresponding peak output range of up to 4 Vp. Designed for wall or direct mounting, the transformer provides a straightforward current sensing solution for machinery, electrical panels and automation systems requiring measurement of currents up to 5 A AC.
Current transformers such as the Carlo Gavazzi A74-105 allow industrial control equipment to monitor AC load current while maintaining electrical isolation between the monitored conductors and the measurement circuitry. Current flowing through the transformer generates a proportional low-voltage analogue output that can be processed by compatible monitoring and control equipment.
The A74-105 is particularly suited to low-current three-phase motor and machinery applications with currents up to 5 A AC. Its fixed configuration eliminates the need for adjustment during installation, while the compact solid-core construction provides a practical solution for permanent current monitoring inside industrial machinery and electrical control panels.
