Why Choose the Carlo Gavazzi A74-105 Current Transformer?
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.
