The PEL51 from Chauvin Arnoux is a single-phase power and energy recorder designed for continuous measurement and recording of electrical parameters in single-phase systems. The device is primarily used for energy monitoring to analyze consumption profiles, identify savings potential, and improve the energy efficiency of buildings or production facilities. It features a compact design, magnetic mounting, and can be installed without interrupting power supply. Power is supplied via the phase within a range of 90 V to 600 V at 50 Hz or 60 Hz, enabling extended measurement campaigns without an external power source.

Applications

The PEL51 is primarily used in energy accounting, where detailed analysis of electricity consumption is required. It is suitable for electricians, facility managers, and energy consultants who need detailed consumption data for energy-saving measures or in preparation for energy audits. The recording of consumption values with timestamps allows comparison before and after optimization measures to verify the effectiveness of actions. The devices are also suitable for checking energy meters, especially in combination with compatible current transformers such as the Mini94.

Functions and Equipment in Detail

The device features a backlit LCD display with blue illumination, enabling dual display for real-time measurements. It measures voltage in the range of 10 VAC to 600 VAC and current via various current transformers, with measurement ranges varying depending on the used clamp. Clamps MN93, MN93A, C193, AmpFlex® A193, and MiniFlex MA194 enable measurements from 5 mA to 2400 A. Measurements are performed using TRMS method, ensuring accurate capture even of non-sinusoidal currents. The devices measure active power (P), reactive power (Q1, N), apparent power (S), distortion power (D), power factor (PF), cos φ, and tan Φ. Additionally, THD (Total Harmonic Distortion) is recorded to evaluate power quality.

Technology Explained Simply

Measured values are recorded at a programmable interval from 1 second to 1 hour, capturing minimum, maximum, and average values. Data is stored on an SD or SDHC card with up to 32 GB capacity. Recording duration depends on card capacity and selected interval. Data can be transmitted via integrated WLAN functionality, with an embedded web server enabling control and display of measurements through a web browser. The PEL Transfer® software is used for device configuration, data download, and analysis. Communication occurs via WLAN, with devices also accessible via an IRD server.

Compatibility and Accessories

The PEL51 is compatible with various current transformers, including clamps MN93, MN93A, C193, AmpFlex® A193, and MiniFlex MA194 in different sizes. These enable current measurement without interrupting the circuit. Additional accessories include the DataView software, a Reeling Box cable winder with magnet, adapter C8, SD cards, a transport case, and power cables. For example, combining with a MiniFlex MA194-250 mm (diameter 70 mm) is suitable for measurements in tight enclosures.

Mounting and Installation

The magnetic mounting allows flexible installation on metallic surfaces, such as in enclosures. Installation can be done without power interruption, as the device is powered via the phase. Connections consist of two 4 mm terminals for voltage measurement and a current connection of type Qualistar. The devices are designed for industrial and commercial environments and comply with safety standard IEC 61010 with a category of 600 V CAT III.

Operational Advantages

The PEL51 offers a reliable and user-friendly solution for energy monitoring. Powering via the phase reduces dependency on external power sources. WLAN communication and the integrated web server enable real-time monitoring and remote control. Recording on high-capacity SD cards ensures long measurement durations. The IP54 protection rating (IEC 60529) protects the device against dust and splashing water, making it suitable for outdoor use. The warranty period is 2 years.

Enclosure and Safety

The enclosure of the PEL51 is protected to IP54 (IEC 60529), ensuring high resistance against dust and splashing water. Dimensions are 180 x 88 x 37 mm (without sensor), and weight is 400 g. The safety standard IEC 61010 with 600 V CAT III ensures safe use in industrial installations. The devices are designed for single-phase systems and measure voltage, current, power, and energy in real time.

Energy Accounting and Analysis

Data recorded with the PEL51 enables detailed energy accounting. Timestamping of measurements allows comparison before and after energy-saving measures. The devices thus support the implementation of energy efficiency measures and preparation for energy audits, especially in the context of ISO 50001 certifications. Analysis of consumption profiles helps identify inefficient consumers and enables targeted optimizations.

Software and Data Analysis

The PEL Transfer® software enables device configuration, downloading of measurement data, and analysis on a PC. Data can be exported in various formats for use in reports or energy accounts. The software supports visualization of measurement values and creation of charts for better interpretation of consumption data.
