The PEL112 from Chauvin Arnoux is a three-phase power and energy recorder without integrated display, designed for continuous measurement and storage of electrical parameters in industrial, commercial, and infrastructure applications. The device serves energy consumption analysis, energy audits, electrical diagnostics, and preventive maintenance. It features three voltage and three current inputs, enabling the capture of active, reactive, and apparent power as well as energy. Measurement is performed using RMS and DC technology, with voltages up to 1000 V and currents up to 10 kA AC or 5 kA DC (depending on the current transformer used). Device functions include calculation of power factor PF, crest factor, THD (total harmonic distortion) for voltage and current, and breakdown of energy losses. Measurements can be taken across various frequency ranges, including DC, 50 Hz, 60 Hz, and 400 Hz, enabling use in shipping and other specific environments.

Applications

The PEL112 is suitable for a wide range of applications, including power generators such as photovoltaic, wind, hydro, and thermal power plants, process industries such as metalworking, glass and paper industries, chemical and food industries, as well as residential and service buildings. It is also used in public infrastructure, transportation, monitoring of lighting systems, streets, highways, tunnels, and railways. In data centres, it supports consumption monitoring and analysis to prevent outages and optimize electricity usage. The devices are suitable for use in refrigerated warehouses, as they can withstand temperatures down to -20 °C.

Functions and Equipment in Detail

The device captures and stores all relevant electrical parameters, including fundamental active power (Pf), symmetrical active power (P+), and asymmetrical active power (Punb). It enables characterization of electric drives and measurement of motor speed, efficiency, and torque via an Android app, without requiring mechanical sensors. Automatic detection of connected current transformer types simplifies installation. Measured values and calculation results are stored on an SD card, enabling recording durations of several months.

Technology Explained Simply

RMS measurement (Root Mean Square) captures the effective value of alternating voltages and currents, which is crucial for accurate energy calculation. DC measurement enables capture of direct voltages and currents. THD calculation (Total Harmonic Distortion) analyses harmonics in the network, which is important for assessing power quality. Self-supply via phase (option) allows the device to be powered independently from the measured network, eliminating the need for external power sources. Measurement occurs simultaneously in each phase with 128 samples per cycle, ensuring high accuracy.

Compatibility and Accessories

The device is compatible with various accessories, including batteries, adapter housings (5A (F) and Essailec), coloured identification parts, the DataView software, a Reeling Box (cable winder with magnet), various clamps (MINI94 (AC), E94, MN93A, C193, J93, PAC93, MN93), a 600 V power adapter for PEL100 V3, a USB-A / USB-B cable, Ampflex and Miniflex cables (A193-800 mm, A193-450 mm, MA194-250 mm, MA194-1000 mm), a transport bag, and a power adapter. The PEL Transfer software enables device configuration, connection verification, downloading of measurement data, and display of results. The software can also convert electricity consumption into Euros (8 tariff zones).

Mounting and Installation

The PEL112 features a magnetic housing, enabling easy and secure mounting without interrupting the network power supply. Installation is carried out at the respective measurement points, requiring appropriate current and voltage transformers. Communication is via USB, Ethernet RJ45, or Wi-Fi. In Wi-Fi server mode, the device can be connected to a network server to allow data reading from any station in the network. In Wi-Fi access point mode, a direct connection to a computer is possible, supporting up to 5 clients.

Operational Advantages

Using the PEL112 enables precise and continuous energy consumption analysis, contributing to energy efficiency optimization, reduction of operating costs, and improved reliability of electrical systems. The integrated PEL Transfer software offers comprehensive analysis capabilities and enables conversion of measured values into monetary values. The long recording duration and robust construction make the device a reliable solution for long-term measurement campaigns across various industries.
