This replacement power supply and battery charger is specifically designed for the earth and earth resistance meters of the C.A 6470N, C.A 6471, and C.A 6472 series by Chauvin Arnoux. It serves as a power source and charging unit for the internal rechargeable batteries of these measuring devices. The device enables reliable and efficient charging, ensuring that the devices are always operational even during mobile use. The input range of AC 100–240 V at 50/60 Hz makes the charger suitable for worldwide use, regardless of local mains voltage. The output is DC 18 V at 1.9 A, providing the necessary power for fast charging.

Applications
This charger is exclusively intended for the specified earth measuring devices. It is used in professional environments where continuous and secure power supply is required for precise measurements on grounding systems, high-voltage masts, or industrial installations. Compatibility with models C.A 6470N, C.A 6471, and C.A 6472 ensures uniform operation and interchangeability within existing equipment.

Functions and Equipment in Detail
The charger features a 2-pole power cable that connects directly to the socket. Power supply is provided via the external output of 18 Vdc / 1.9 A, specifically designed for the battery technology of the measuring devices. The robust construction is designed for professional use, with electrical safety guaranteed up to 50 V CAT IV. The use of a universal power supply enables operation in various countries without modification.

Technology Explained Simply
Power supply is provided via an external power adapter, delivering the required voltage and current for charging the internal batteries. The output voltage of 18 Vdc is precisely matched to the battery technology of the devices to ensure safe and efficient charging performance. The input voltage of AC 100–240 V ensures universal usability, regardless of local mains voltage. Power supply is delivered via a 2-pole power cable connected directly to the socket.

Compatibility and Accessories
The charger is compatible with earth measuring devices C.A 6470N, C.A 6471, and C.A 6472. It can be used as a replacement for the original charger. Additionally, various accessories are available for these devices, such as an accessory kit for earth and earth resistance measurement with 4 electrodes (100 m or 150 m), an optical USB cable, a Li-Ion battery charging station, DataView software, C182 current clamp transformers, a probe for continuity testing, an adapter for battery charging via cigarette lighter, and a 2 m test lead for current clamps. These components extend the functionality of the measuring devices and enable comprehensive testing of grounding systems.

Installation and Mounting
Installation is performed by directly connecting the 2-pole power cable to a suitable socket. The charger is connected to the measuring device, after which power supply is automatically activated. No additional mounting or installation work is required. Use is exclusively for stationary operation, as the device is not designed for mobile or portable applications.

Operational Advantages
