General
Enclosure diameter	16 mm

The MINI 102 current transformer from Chauvin Arnoux is a compact measuring accessory for precise alternating current measurement in applications with low to medium power in commercial and industrial environments. It serves as a connection device for multimeters and enables the measurement of currents in the range of 0.05 A to 200 A AC. Due to its maximum clamping diameter of 16 mm, it is particularly suitable for use in confined spaces where only small conductors or cables can be enclosed.

Applications

The MINI 102 is used in electrical engineering and industrial operations where precise current measurement is required for low to medium loads. It is suitable, for example, for monitoring consumers, testing circuits, or diagnosing current consumption in smaller installations. The compact design allows use in tight installation situations, such as in enclosures or when testing control wiring.

Functions and Equipment in Detail

The current transformer operates with a turns ratio of 1000/1, meaning that a measured current of 1000 A at the input is displayed as 1 A at the output. The typical accuracy is ≤ 1 %, ensuring high measurement accuracy for the intended applications. The output signal is an alternating current transmitted via an insulated cable with a 4 mm diameter connector to the measuring device. This connector is standard for multimeters and enables a safe and reliable connection.

Technology Explained Simply

The current transformer uses the principle of inductive current measurement: when a conductor carrying alternating current is passed through the clamp, the current generates a magnetic field that induces a secondary voltage in the clamp. This voltage is output proportionally to the primary current. The overvoltage protection at the output protects the device and the connected measuring instrument if the clamp is disconnected from a live conductor. This prevents damage from inductive voltage spikes.

Compatibility and Accessories

The MINI 102 is designed as an accessory for multimeters that have a corresponding alternating current input with a 4 mm connector. It is not designed for direct display of current values, but serves as a signal converter to be used in combination with a suitable measuring device. Use with other devices not designed for this connector type is not intended.

Installation and Mounting

Installation is carried out by simply clamping the conductor to be measured with the clamp. The clamp is positioned so that the conductor is fully within the clamping area. Connection to the measuring device is made via the supplied cable with the 4 mm connector. The operating instructions, included in the delivery, provide guidance on correct handling and avoiding measurement errors.

Advantages in Operation

The MINI 102 offers high measurement accuracy in a compact design, making it particularly suitable for use in confined spaces. The integrated overvoltage protection increases safety when working with electrical installations. The simple handling and direct connection to multimeters enable quick and reliable current measurement without additional tools or adapters.
