A82-10100 – CURRENT TRANSFORMER 100 AAC

Why Choose the Carlo Gavazzi A82-10100 Current Transducer?

The Carlo Gavazzi A82-10100 is a compact and reliable AC current transducer designed for measuring electrical currents up to 100 A AC in industrial automation, machinery and energy monitoring applications. As part of the Carlo Gavazzi A82 Series, it converts the measured AC current into a standard 0–20 mA DC analogue output for straightforward integration with PLCs, controllers, meters and monitoring systems.

The A82-10100 uses a solid-core, non-invasive current sensing design, allowing the monitored conductor to pass through its 27 mm aperture. This provides electrical isolation between the primary conductor and measurement circuitry while avoiding the need to place the transducer directly in series with the monitored load.

Designed for currents up to 100 A AC, the A82-10100 is powered from its output loop and operates from a 10–40 V DC loop supply. Its 0–20 mA DC output, compact 95 × 67.5 × 20 mm housing and direct mounting arrangement make it well suited to industrial control cabinets, motors, pumps, machinery and electrical load monitoring applications.

Reliable AC Current Measurement for Automation Systems

Current transducers such as the Carlo Gavazzi A82-10100 convert the current flowing through an electrical conductor into a standard analogue signal that can be processed by industrial control and monitoring equipment. The 0–20 mA DC output makes the measured current straightforward to interface with compatible PLC analogue inputs, process controllers, monitoring equipment and data acquisition systems.

The A82-10100 uses a solid-core sensing arrangement with a 27 mm aperture, allowing the primary conductor to pass through the transducer without a direct electrical connection to the measurement circuitry. This combination of isolated current measurement, loop-powered operation and a standard analogue output makes it a practical choice for permanent current monitoring within industrial machinery and electrical systems.
