General
Enclosure diameter	100 mm

The flexible current transformer of the MA200 series by Chauvin Arnoux is an isolated measuring instrument for precise detection of alternating currents with high frequencies and dynamic waveforms. It is specifically designed for use with oscilloscopes and enables the visualization of complex current signals, particularly in applications involving transients, such as those occurring in electronic power supplies or welding stations. The device features high bandwidth and precise signal reproduction, allowing even rapidly changing current waveforms to be measured reliably.

Applications
The MA200 current transformer is suitable for measuring alternating currents in the range of 500 mA to 3000 A (RMS) and up to 4500 A (peak). It is ideal for analyzing dynamic currents and high-frequency signals in electrical and electronic engineering. Typical application scenarios include monitoring power supplies, diagnosing switching operations in power electronics, and investigating transients in industrial plants. The isolated design ensures safe measurement even in electrically demanding environments.

Functions and Equipment in Detail
The flexible current transformer encircles the conductor to be measured with an encircling diameter of 100 mm (circumference 35 cm), allowing it to be installed even in tight or inaccessible locations. The output signal is provided as alternating voltage via a BNC coaxial connector, which can be connected directly to oscilloscopes. The turns ratio is 1 mV per ampere, enabling direct scaling of the measured current. The typical accuracy is ≤ 1% + 0.3 A, which is sufficient for precise measurements in technical applications.

Technology Explained Simply
The bandwidth of 5 Hz to 1 MHz enables the capture of very fast current changes, which is crucial for analyzing pulses and transient events. The isolated construction protects the user and the measuring instrument from dangerous voltages. The safety categories 600 V CAT IV and 1000 V CAT III confirm suitability for measurements in electrical installations with high voltages, for example in distribution systems or industrial machinery. The device is designed for use in electrical engineering, where high safety requirements apply.

Compatibility and Accessories
The current transformer is specifically designed for connection to oscilloscopes. Suitable accessories include a power adapter for the MiniFLEX MA200, a set of two adapters BNC female/4mm male, and opening clamps for the MiniFLEX (yellow, 5 pieces). These components facilitate integration into existing measurement systems and allow flexible adaptation to various measuring instruments.

Mounting and Installation
The flexible design of the current transformer allows for easy and quick wrapping around the conductor to be measured. No additional mounting or drilling is required. Connection to the oscilloscope is made via the integrated BNC connector. Installation is tool-free and quick, enabling measurement to start immediately.

Operational Advantages
The MA200 offers high bandwidth and accuracy, combined with safety through isolation and high safety categories. The flexible shape allows easy adaptation to different conductor cross-sections. Direct drive to oscilloscopes enables immediate signal visualization, accelerating fault diagnosis and system analysis. The safety categories 600 V CAT IV / 1000 V CAT III guarantee safe operation in industrial and electrical installations.
