The PEL52 from Chauvin Arnoux is a two-phase power and energy recorder designed for precise measurement and recording of electrical parameters in single-phase, two-phase, and three-phase systems. The device is used for energy balancing, monitoring electricity consumption, and analyzing energy efficiency and savings potential in buildings and industrial facilities. Thanks to self-powering via the phase (90 V to 600 V at 50–60 Hz), it is suitable for long-term measurement campaigns without requiring external power sources. The magnetic mounting allows flexible installation, even in confined enclosures, without interrupting the circuit.

Applications

The PEL52 is used to analyze energy consumption in electrical systems, particularly in the context of energy-saving measures and energy efficiency projects. It is suitable for monitoring consumers, identifying energy losses, and validating optimization measures. The time-stamped measurement data enable direct comparison before and after interventions, allowing the effectiveness of network or connected device adjustments to be proven. The devices are also relevant for companies aiming for ISO 50001 certification or required to conduct mandatory energy audits.

Functions and Equipment in Detail

The device features two measurement channels (2V / 2I), which can be used for measuring two single-phase systems or one two-phase system. It measures voltage (10 VAC to 600 VAC), current (depending on the current transformer used, e.g., 500 mA to 200 A with MN93, 500 mA to 2400 A with AmpFlex® A193), and power parameters such as active power (P), reactive power (Q1, N), apparent power (S), distortion power (D), and power factor (PF, cos ϕ, tan Φ). Measurements are performed using TRMS methods, enabling accurate capture of non-sinusoidal signals. Harmonic distortions are recorded via THD (Total Harmonic Distortion). The display is a backlit LCD with blue illumination and dual display for real-time measurements.

Technology Explained Simply

The device is powered via the voltage input, making it independent of external power sources. Measurement values are recorded at intervals from 1 second to 1 hour, capturing minimum, maximum, and average values. Data storage is on an SD card (up to 8 GB) or an SDHC card (up to 32 GB), which is programmable. Data can be transmitted via WLAN, with an integrated web server enabling control and display of measurement values through a web browser. Communication occurs via Wi-Fi, enabling real-time monitoring and remote access.

Compatibility and Accessories

The PEL52 is compatible with various current transformers, including clamp meters MN93, MN93A, C193, AmpFlex® A193, and MiniFlex MA194, selected according to application and required measurement range. Software DataView and PEL Transfer® enable configuration, data transfer, and analysis of measurement results. Additional accessories such as a carrying case, cable reel box (Reeling Box), adapter C8, power cable, and various SD cards are available to support handling and use of the device.

Mounting and Installation

The magnetic mounting allows quick and secure installation on metallic surfaces, such as enclosures. Installation is performed without interrupting the circuit, as current transformers are placed directly around the conductors. Voltage connections (3 terminals 4 mm) and current connections (Type Qualistar) are clearly marked, enabling secure connections. Operation is via the display and integrated software, with the quick start guide (QSG) and user manual (NF) providing support.

Advantages in Operation

The PEL52 offers a compact, user-friendly solution for energy monitoring. Self-powering and magnetic mounting reduce installation time and complexity. WLAN communication and the integrated web server enable flexible remote monitoring. Recording of measurement values with timestamps and storage on SD cards provide detailed documentation for later analysis. Compatibility with various current transformers expands application possibilities in different scenarios. The safety standard IEC 61010 600 V CAT III ensures safe operation in industrial environments. The housing is rated IP54 (IEC 60529), protecting against dust and splashing water, enabling use in indoor and slightly damp environments. The warranty is 2 years.
