General
Input voltage	100 – 260 V
Input frequency	0 – 440 Hz

The PA40W-2 power supply from Chauvin Arnoux is a replacement part for the power analyzer C.A 8345 and for the oscilloscopes of the OX 9000 series. It serves as a power supply and charger for the integrated batteries of these measuring instruments. The device is designed for use in industrial and commercial environments where high safety requirements apply to measuring and power supply technology.

Applications
This power supply is specifically intended for use with the mentioned measuring instruments. It enables continuous power supply during measurement and charging of the internal batteries, ensuring the operational readiness of the devices. The safety category 600 V CAT III makes it suitable for applications in electrical installations where high voltages and transient energy input may occur, such as in power supply, manufacturing technology, or machine maintenance.

Functions and Equipment in Detail
The device performs two central functions: powering the devices via the mains and charging the internal batteries. The included cable ensures a direct and secure connection to the device. The maximum output power is 40 W, which is sufficient to operate the devices and simultaneously charge the battery. The input voltage range of 100 to 260 V and frequency of 0 to 440 Hz allow use in various countries and under different mains conditions, including industrial environments with variable frequency.

Technology Explained Simply
The safety category 600 V CAT III means that the power supply is designed for use in electrical installations that may carry voltages up to 600 V under normal operating conditions. This category is typical for measuring instruments directly connected to electrical installations and protects against dangerous overvoltages. The wide input voltage range of 100 to 260 V allows use in Europe, North America, and other regions with different mains voltages. The frequency range of 0 to 440 Hz also covers non-50/60 Hz networks, as found in industrial environments or special installations.

Compatibility and Accessories
The power supply is compatible with the power analyzer C.A 8345 and the oscilloscopes of the OX 9000 series. It is designed as a replacement part to replace original accessories if they are defective or lost. Use with other devices is not intended and not guaranteed.

Installation and Mounting
Installation is carried out by directly connecting the included cable to the measuring instrument. No additional mounting work or tools are required. The safety instruction manual, included in the delivery, contains guidance on correct handling and avoiding hazards.

Operational Advantages
Due to the universal input voltage and high safety category, the power supply is suitable for worldwide use and in demanding environments. The combination of power supply and battery charging function reduces the need for additional devices and increases the operational readiness of the measuring instruments. The robust construction and compliance with safety standards ensure reliable operation under industrial conditions.
