General
Output voltage	1 V AC

The three-phase adapter from Chauvin Arnoux is a specific measuring accessory designed for use with network, energy, and power analysers from the Qualistar C.A 83xx / C.A 84xx series, as well as for the PEL 10X / PEL 11X models. It converts 5 A AC transformer current into a 1 V AC voltage, enabling precise measurements in three-phase circuits. The design ensures high measurement accuracy and safe operating conditions through complete galvanic isolation between the input and output circuits.

Applications
This adapter is primarily intended for professional applications in the field of electrical installation analysis and monitoring. It is used to convert current values in a three-phase system into proportional voltage values, which can then be captured and evaluated by compatible analysers. This is particularly relevant for diagnosing power quality, measuring energy consumption, or monitoring power parameters in industrial or commercial electrical installations.

Functions and Features in Detail
The adapter features three independent measurement circuits, each capable of accepting a phase current of up to 5 A AC and converting it into a corresponding 1 V AC voltage. The galvanic isolation between input and output protects the measuring devices from voltage surges and enables safe measurement even in electrically demanding environments. The conversion is performed with high precision, ensuring reliable and reproducible measurement results.

Technology Explained Simply
The operation is based on a current-to-voltage converter, which transforms the flowing current into a proportional voltage. The 5 A AC current is converted into a 1 V AC voltage, allowing the measuring devices to capture current values via voltage inputs. Galvanic isolation is achieved through insulation between the input and output circuits, increasing safety and preventing interference between phases.

Compatibility and Accessories
The adapter is specifically designed for analysers from the Qualistar series (C.A 83xx / C.A 84xx) and for the PEL 10X / PEL 11X models from Chauvin Arnoux. It is not a universal accessory and requires use with the specified devices. Connection is made via three-phase banana plugs, which are connected to the TI outputs of the analysers.

Mounting and Installation
Installation is performed by directly connecting the adapter to the TI outputs of the compatible analysers. The connections are designed for three-phase systems, with each phase current measured via a separate channel. Connection is made using banana plugs, which are standard on the devices. No additional tools or mounting procedures are required.

Operational Advantages
Using this adapter enables precise and safe measurement of current values in three-phase systems. Galvanic isolation protects the measuring devices and increases operator safety. Conversion into voltage allows use of the analogue inputs of the analysers, improving measurement accuracy and result reliability. The independent circuits ensure that each phase is measured without interference from the other phases.

Scope of Delivery
The scope of delivery includes 1x three-phase adapter.
