The Mini94 AC current clamp from Chauvin Arnoux is a current transformer for non-invasive measurement of alternating currents in the range of 50 mA to 200 A. The device is specifically designed for use with power and energy analysers, particularly with the Qualistar2 and PEL power loggers from the company. The current clamp enables current measurement without interrupting the circuit, ensuring safe and undisturbed measurement of the electrical system. Due to its high accuracy class 0.2, it is particularly suitable for precise measurements in energy and power analysis, for example for checking energy meters.

Applications

The Mini94 AC current clamp is used in installations with network frequencies between 48 Hz and 65 Hz. It is intended for measuring alternating currents in industrial, commercial and technical installations where high measurement accuracy and reliability are required. The clamp is particularly suitable for users working with power and energy analysers, as it features a special 4-pole, sheathed plug compatible with the Qualistar Class A devices of the latest generation from Chauvin Arnoux. Via this connection, the device automatically recognises the current clamp, simplifying operation and reducing error sources.

Functions and equipment in detail

The current clamp has a clamping diameter of 16 mm, enabling measurement on conductors with the corresponding cross-section. The output signal is transmitted via a 3 m long cable ending in the 4-pole plug. The high accuracy of the Mini94 in amplification and phase ensures reliable and reproducible measurement values. The clamp is designed for use in electrical installations complying with the IEC 61010 standard, with categories CAT III – 600 V and CAT IV – 300 V, ensuring safe use in industrial and energy technology environments.

Technology explained simply

A current transformer such as the Mini94 operates on the principle of electromagnetic induction. When current flows through the conductor placed in the clamp, it generates a magnetic field that is detected by the clamp and converted into a proportional output signal. This signal is transmitted via the 3 m long cable to the measuring device. Accuracy class 0.2 means that the deviation of the measured value from the actual value is at most 0.2 %, which is sufficient for precise analyses. The frequency bandwidth of 48 Hz to 65 Hz covers the usual network frequencies in Europe and other regions.

Compatibility and accessories

The Mini94 AC current clamp is specifically developed for use with Qualistar2 and PEL power loggers. Compatibility is ensured by the 4-pole, sheathed plug, which enables automatic recognition of the current clamp by the measuring device. This reduces error susceptibility during device configuration and speeds up the measurement process. The clamp is not intended for use with other devices unless they support the specific connection standard.

Installation and mounting

Installation of the Mini94 is carried out by simply clamping the conductor to be measured. The clamp is placed around the conductor without interrupting it. The measurement cable with the 4-pole plug is connected to the measuring device. Mounting requires no special tools and can be carried out quickly and safely. The clamp is compact with dimensions of 130.4 x 46 x 34 mm and a weight of 250 g, enabling convenient handling.

Advantages in operation

The Mini94 AC current clamp offers high measurement accuracy required for precise energy and power analysis. The non-invasive measurement method protects the electrical system from interruptions and increases operator safety. Automatic recognition by compatible measuring devices reduces operational complexity and minimises errors. The robust construction and compliance with the IEC 61010 standard with categories CAT III – 600 V and CAT IV – 300 V ensure safe use in various application environments. The warranty is 2 years, highlighting the reliability of the product.
