The Chauvin Arnoux MINI102 is an amperometric clamp for measuring alternating current with a nominal current rating of 200 A AC. It is designed for use in confined spaces such as enclosures, power switches, or control cabinets, where a compact design is required. The clamp features a jaw with a maximum diameter of 16 mm and provides an output signal in the form of alternating current (A AC), delivered via a cable with insulated, bent connectors having a diameter of 4 mm. The transformation ratio is 1000:1, meaning the measured current is output at a 1:1000 ratio on the secondary side. The clamp is designed for use with multimeters, measuring instruments, or data acquisition systems that have current or voltage inputs.

Applications

The MINI102 is suitable for measurements in electrical installations, particularly in industrial and commercial environments where access to cables is limited. It is frequently used in maintenance, servicing, and diagnostics of electrical systems to monitor the current consumption of individual cables or devices. The compact design enables precise measurement in confined spaces, such as those found in enclosures or control units. The clamp is suitable for use in electrical installations with voltage categories of 600 V CAT III and 300 V CAT IV, qualifying it for use in industrial and commercial installations.

Functions and Equipment in Detail

The clamp operates on the principle of a current transformer and provides a proportional output signal that can be directly connected to measuring instruments. The output signal is available via a 1.5 m long, double-insulated cable with two insulated, bent connectors with a diameter of 4 mm. The clamp is surge-protected, providing additional safety during measurement. The bandwidth of the clamp ranges from 48 Hz to 500 Hz, enabling accurate measurement at standard frequencies such as 50 Hz or 60 Hz. The maximum load impedance is 10 Ω, ensuring compatibility with a wide range of measuring instruments.

Technology Explained Simply

The MINI102 uses the principle of electromagnetic induction to measure current in a conductor without interrupting it. When the conductor is passed through the clamp, the flowing current generates a magnetic field that induces a voltage in the secondary winding of the clamp. This voltage is proportional to the current in the conductor and is transmitted to the measuring instrument via the output cable. The transformation ratio of 1000:1 means that a current of 200 A in the conductor produces an output signal of 200 mA. The clamp delivers True RMS values when connected to a True RMS measuring instrument, enabling accurate measurement even with non-sinusoidal signals.

Compatibility and Accessories

The clamp is designed for use with multimeters, data loggers, or other measuring instruments that have current or voltage inputs. The output connectors with a 4 mm diameter are universally applicable and fit most standard measuring instruments. Compatibility with other devices depends on the load impedance and input range of the respective device. The clamp is suitable for use in electrical installations with voltage categories of 600 V CAT III and 300 V CAT IV, ensuring high safety during measurement in industrial environments.

Installation and Mounting

Installation of the clamp is performed by simply clamping around the conductor to be measured. The clamp is designed for use in confined spaces and can be easily placed in enclosures or control cabinets. The cable connection is made via the insulated connectors with a 4 mm diameter, which are directly connected to the measuring instrument. The clamp requires no additional tools or mounting aids. The operating temperature range is from -10 °C to +50 °C, and the storage temperature range is from -40 °C to +80 °C. The clamp is suitable for use in environments with a relative humidity of up to 85 % RH, with humidity decreasing linearly above 35 °C.

Operational Advantages

The MINI102 offers high precision in current measurement, especially in confined spaces where other measuring instruments cannot fit. The compact design and low weight of approximately 180 g enable easy handling. The clamp is surge-protected and provides high safety during measurement in electrical installations. The use of a double-insulated cable with insulated connectors further increases safety. The clamp is suitable for use in industrial and commercial environments and complies with safety standards EN 61010-1, EN 61010-2-031, and EN 61010-2-032. The clamp is CE-certified and meets the requirements of EN 61326-1 for electromagnetic compatibility.

Protection Rating and Environmental Conditions

The clamp has a protection rating of IP40, meaning it is protected against solid foreign objects with a diameter of at least 1 mm, but not against water. The clamp is suitable for indoor use, as it is not waterproof. The operating temperature range is from -10 °C to +50 °C, and the storage temperature range is from -40 °C to +80 °C.
