The USB power adapter P01651023 from Chauvin Arnoux is a power supply unit for continuous operation and charging of mobile measuring instruments of the brand. It enables direct power supply via a socket and is designed for an input voltage of 110 to 240 V at 50/60 Hz, ensuring worldwide usability. The device delivers a constant output voltage of 5 V at a current of 1 A via a USB Type-A socket (female). The delivery includes a charging and connection cable with USB Type-A (male) at one end and USB Type-µ-B (male) at the other end. The cable length is 1.8 m, which is sufficient to position the device flexibly within the working area.

Applications

The power adapter is specifically designed for use with a range of Chauvin Arnoux measuring instruments. It serves both as a charging unit for battery-operated devices and as a continuous power supply to extend battery life or enable operation without batteries. The devices compatible with this adapter include the MiniFLEX and AmpFLEX series (models MA110, MA130, A110, A130), PAC clamps (models PAC15, PAC16, PAC17, PAC25, PAC26, PAC27), and measuring instruments for physical quantities (C.A 1110, C.A 1227, C.A 1246, C.A 1821, C.A 1822, C.A 1823, C.A 1510). These devices are used in electrical engineering, facility management, and industrial measurement technology.

Functions and Equipment in Detail

The adapter features an integrated power supply unit that converts the input voltage of 110 to 240 V into a stable output voltage of 5 V. The output power is 5 V/1 A, sufficient to supply and charge the mentioned devices. The included cable enables a direct connection between the power adapter and the device. The use of a USB Type-µ-B connector on the device side is typical for older mobile measuring instruments that feature a serial interface or a USB charging port. The cable length of 1.8 m provides sufficient mobility, for example, to place the device on a workbench while the adapter is connected to a nearby socket.

Technology Explained Simply

The power adapter functions as a voltage converter, transforming mains voltage (110–240 V) into a safe, low voltage (5 V). This voltage is suitable for most mobile electronic devices, especially those equipped with USB charging ports. Power supply occurs via the USB protocol, with an output power of 5 V/1 A (i.e., 5 W), sufficient to operate the mentioned devices. The input voltage range of 110–240 V and frequency of 50/60 Hz make the adapter suitable for use in various countries without requiring an additional voltage converter. The output interface is a USB Type-A socket (female), which can be connected to a standard USB cable.

Compatibility and Accessories

The adapter is specifically developed for the mentioned Chauvin Arnoux devices. Compatibility includes the MiniFLEX and AmpFLEX series, PAC clamps, and various measuring instruments for physical quantities. The use of the included USB Type-A to µB cable is required to establish the connection to the device.

Installation and Mounting

Installation is carried out by simply connecting the power adapter to a socket and connecting the cable between the adapter and the device. No additional tools or mounting procedures are required. The operating instructions, included in the delivery, contain instructions for correct use.

Operational Advantages

Using the USB power adapter enables continuous power supply to the devices, reducing dependence on batteries. This is particularly advantageous for extended measurement tasks or for use in stationary applications. The worldwide usability, due to the wide input voltage range, also makes the adapter suitable for international deployment. The combination of power adapter and cable in one set provides a compact and user-friendly solution.
