The flexible current transformer A193-610 IP67 AmpFlex from Chauvin Arnoux is an AC current sensor for use with Qualistar and PEL measurement technology, particularly models PEL 105, PEL 106, PEL 115, and the C.A 8436. It is designed for precise measurement of alternating current in industrial and technical installations where high flexibility and reliability are required. The device is designed for use in demanding environments, especially in areas with high electrical voltages, and meets safety requirements according to IEC 61010. The IP67 protection rating makes the current transformer dust- and water-tight, allowing it to be used outdoors or in humid environments.

Applications

The current transformer is specifically designed for measuring AC current in large conductors or in hard-to-reach locations. Its flexible design allows it to encircle cables with a diameter up to 190 mm, with a total loop length of 610 mm. This makes it particularly suitable for applications in power supply, industrial electrical engineering, building automation, and maintenance of electrical installations. The measurement ranges vary depending on the connected device, with the lower limit at 100 mA and the upper limit at 10 kA, covering a broad range of applications.

Functions and Equipment in Detail

The current transformer operates as a passive sensor that detects the magnetic flux around a conductor and converts it into a proportional electrical signal. The measurement is contactless, preserving the electrical insulation of the measured object. Compatibility with various devices such as the PEL 105, PEL 106/115, and the C.A 8436 enables flexible integration into existing measurement systems. The measurement ranges vary by device: when used with the PEL 105, the range is 200 mA to 10 kA AC; with models PEL 106/115 and C.A 8436, it is 100 mA to 10 kA AC.

Technology Explained Simply

The IP67 protection rating means the current transformer is fully protected against dust and can be submerged in water for a short time without damage. This is especially important for installations outdoors or in humid environments such as basements, cooling systems, or production halls. The safety categories CAT III 1000 V and CAT IV 600 V according to IEC 61010 ensure the sensor is suitable for use in electrical installations with the corresponding voltage class, increasing the safety of the operator and the installation. The flexible loop made of a robust material allows for easy handling and adaptation to different conductor diameters.

Compatibility and Accessories

The current transformer is specifically developed for use with the mentioned Qualistar and PEL devices. It is directly connected to these devices to enable current measurement. As accessories, a set of colored identification parts is offered, which can be used for better identification of measurement points or conductors.

Mounting and Installation

Installation is performed by encircling the conductor to be measured with the flexible loop of the current transformer. The loop is then connected to the measuring device. Mounting requires no tools and can be carried out even in live installations, as no electrical connections to the conductor are necessary. The user manual, included in the delivery, provides guidance on correct handling and application.

Advantages in Operation

The flexible current transformer offers high measurement accuracy with minimal impact on the electrical installation. The contactless measurement reduces the risk of short circuits or electric shocks. The IP67 protection rating and high safety categories increase the reliability and lifespan of the device. Compatibility with various measuring devices enables flexible use in existing systems. The long loop length and large encircling diameter facilitate application on large or hard-to-reach conductors.
