General
Diameter	110 mm

The MA500 MiniFlex from Chauvin Arnoux is a flexible AC current transformer, specifically developed for use with photovoltaic test equipment such as the FTV500. It enables precise measurement of alternating currents in the range of 1 to 3000 amperes and is particularly suitable for use on difficult-to-access or irregularly shaped conductors due to its flexible design. The transformer has a diameter of 110 mm, making it suitable for a wide range of cable diameters in industrial and photovoltaic applications. The design is intended for easy handling and quick installation, enabling efficient measurement procedures.

Flexible current transformer
The MA500 MiniFlex is designed as a flexible current transformer, meaning it can be wrapped around the cable to be measured like a hose, without the need to cut or clamp the cable. This design is particularly advantageous for measurements in existing installations, where interrupting the current flow is not possible or desirable. The flexibility of the transformer allows adaptation to different cable diameters within the maximum diameter of 110 mm.

Applications
The current transformer is primarily intended for use in photovoltaic systems, especially in combination with the FTV500 tester. It is used to measure alternating currents in PV systems to check the performance, efficiency, and safety of the installation. The application typically occurs during commissioning, maintenance, or diagnosis of photovoltaic systems, where precise current measurement without physical modification of the installation is required.

Functions and equipment in detail
The MA500 MiniFlex measures alternating currents in the range of 1 to 3000 amperes. The measurement is contactless, with the transformer detecting the magnetic field around the cable and converting it into a proportional electrical signal. This signal is transmitted to the connected measuring device, such as the FTV500, where it is converted into current values and displayed. The design ensures high measurement accuracy while maintaining robustness.

Technology explained simply
The transformer is based on current transformer technology, where a magnetic core focuses the magnetic field lines of the current being measured. The use of a flexible core allows the transformer to be wrapped around the cable without requiring a fixed mechanical connection. The output is via a standardized connector compatible with the FTV500. The current measurement is in the alternating current (AC) range, which is relevant for most applications in photovoltaics and electrical engineering.

Compatibility and accessories
The MA500 MiniFlex is specifically developed for use with the photovoltaic tester FTV500 from Chauvin Arnoux. Compatibility is ensured through the specific interface and signal transmission.

Mounting and installation
Installation is done by simply wrapping the flexible transformer around the cable to be measured. It is important that the cable is fully inside the transformer and no air gaps or shifts occur to avoid measurement errors. The transformer is then connected to the FTV500 test device. Installation requires no special tools or additional components.

Advantages in operation
The MA500 MiniFlex offers the advantage of contactless, non-invasive current measurement, minimizing operational disruptions to installations. The flexibility of the transformer allows quick and easy adaptation to various cable diameters, increasing work speed. The specific design for the FTV500 ensures high measurement accuracy and reliability in photovoltaic applications.
