Frequency

The Chauvin Arnoux L412 is a 2-channel current recorder designed for continuous recording and documentation of current and frequency values in electrical installations. The device is particularly suitable for industrial maintenance, monitoring of electrical circuits, and applications in photovoltaic systems, where intermittent disturbances or anomalies must be detected and analyzed. The L412 features integrated WiFi communication, enabling remote monitoring and control, as well as an integrated web server, allowing control via web browsers on smartphones, tablets, or PCs. Data can be transferred via USB, WiFi, or the IRD server DataView Synch, ensuring flexible and secure data processing.

Applications

The L412 is used in various industrial and technical environments, particularly where detailed analysis of power consumption, load behavior, or power quality is required. It is suitable for monitoring single-phase and multi-phase distribution systems, with measurements possible at outlets, lines, or circuits. The automatic detection of connected current transformers simplifies setup and increases flexibility. The L400 device series, to which the L412 belongs, is specifically designed for detecting signal anomalies and fluctuations, thereby making error diagnosis in electrical systems more efficient.

Functions and Equipment in Detail

The L412 features two measurement channels, each of which can be connected to an external current transformer. The measurement ranges depend on the sensors used, and the device is compatible with a wide range of AC current transformers. The sampling rate is 1 measurement per second, with data stored in aggregation intervals from 1 to 60 minutes. This allows flexible adaptation to different data logging requirements. The device includes an LCD display with backlighting, supporting real-time display of measured values and configuration of the measurement campaign. The storage capacity is 8 GB, enabling high data depth for extended measurement campaigns.

Technology Explained Simply

Power supply is either via three AA batteries or USB, enabling flexible use in mobile or stationary scenarios. Battery life is 3 days of recording without WiFi under normal use, and up to 10 days in Extend mode. The IP54 protection rating ensures protection against dust and splashing water, making the device suitable for industrial environments. Electrical safety complies with standards 600 V CAT IV and 1 000 V CAT III, enabling safe measurements in high-voltage environments. The operating temperature ranges from -20°C to 50°C, allowing use in various climatic conditions. Dimensions are 147 x 34 x 72 mm, and weight is approximately 350 g.

Compatibility and Accessories

The L412 is compatible with a wide range of current transformers, including models Ampflex A193-800mm (diameter 250 mm), Ampflex A193-450 mm (diameter 140 mm), Miniflex MA194-1000 mm (diameter 300 mm), as well as clamps such as clamp MINI94 (AC), clamp MN93A, clamp C193, and clamp MN93. For data processing, the DataView software is available, enabling data retrieval, graphical representation, and export to Excel format. Additional accessories include a USB power adapter, a transport case (120 x 245 x 60 mm), and a shock protection case + Multifix, enhancing device mobility and protection.

Installation and Mounting

Installation involves connecting the current transformers to the L412’s measurement channels. Cable length is 1.2 m, allowing flexible placement. Sensors are available in diameters of 100 mm and 350 mm, enabling adaptation to various conductor cross-sections. Configuration is done via the display or the integrated web server, where settings such as measurement range, frequency, and aggregation interval can be adjusted. Connection to a PC or network is via WiFi or USB.

Operational Advantages

The L412 offers high flexibility through the combination of local and remote data transmission. Remote readability via WiFi and web server enables real-time monitoring, even from mobile devices. Automatic detection of connected current transformers reduces setup time. The high storage capacity of 8 GB allows long-term measurement campaigns without data loss. Electrical safety according to CAT IV 600 V and CAT III 1000 V ensures safe operation in high-voltage environments. The IP54 protection rating makes the device robust against environmental influences. The DataView software supports analysis of recorded data and enables export to common formats such as Excel.

The L400 data logger series, to which the L412 belongs, is designed for industrial maintenance and monitoring of electrical systems. The devices are designed for recording current and frequency values and offer a flexible, secure, and reliable solution for data acquisition in technical installations.
