Algodue Elettronica: MID energy meters, network analysers and Rogowski coils made in Italy

Overview

Algodue Elettronica has made electricity measurement products at Maggiora, in the province of Novara about 50 km from Milan, since 1986. Its company page describes a 3,000 square metre manufacturing site and an in-house research and development department that takes projects from concept to production. The company calls itself a specialist in electricity metering systems, and the catalogue stays close to that: energy meters, network analysers, power-quality analysers, Rogowski coils, current transformers and the software that configures them.

Two things set it apart. The first is Rogowski coils. Algodue makes its own MFC flexible coils and integrators, sells analysers bundled with them, and holds UL listings for the coils, which suits retrofits where a solid-core CT would mean opening a live conductor. The second is customisation. Its projects page offers three levels, from rebranding standard products with another company's name, panels, packaging and communication settings to fully custom designs for the customer, which makes Algodue a supplier behind other brands as well as under its own.

The company is part of the Socomec Group, the French maker of low-voltage power equipment, and the 2026 logo on its website carries the Socomec Group endorsement. Algodue cites the group's manufacturing capacity and economies of scale for its custom work.

MID energy meters

The MID energy meter range lists 15 DIN-rail models. The UEM80 is a four-module three-phase meter for 80 A direct connection with MID class B active energy, sold as UEM80-4D R with RS-485 Modbus RTU or ASCII, as an M-Bus version and as UEM80-4D E with Ethernet Modbus TCP, each also in a non-MID class 1 version. Single-phase meters run from the 40 A UEM40-2C to the 100 A UEM100-2; the UEM100 is a 100 A three-phase meter; the UEM6C and UEMCT connect through 1 or 5 A CTs; and the UEM2L and UEM4L measure two or four loads through a CT block. The UEC80 and UEC6C-X are programmable versions.

Analysers

The network analysers are the UPM209 (DIN rail) and UPM309 (96 x 96 mm) with built-in Modbus over RS-485 or Ethernet, smart kits of each with three MFC150 coils, and the modular UPA20, UPA30 and UPA41, which take plug-in communication, I/O and temperature modules. The PQM4000 is a class A power-quality analyser in a 192 x 144 mm panel housing.

Coils, CTs and software

Rogowski coils come in 7, 8 and 12 mm cross sections, passive or with an integrator, with RPS50 and RPS51 integrators and the FCA3000 three-phase converter. A March 2024 update added a 0.5% accuracy class. Standard and custom CTs and free configuration tools complete the range. Algodue publishes list prices for many products, from about €105 for a single-phase MID meter.

Technology

Modbus and M-Bus

Algodue publishes one Modbus protocol manual, version 011 of August 2021, for its meters with integrated Modbus or Ethernet interfaces. Each value has a hexadecimal register address that is sent as printed, an integer in a stated unit such as millivolts, milliamps, milliwatts or tenths of a watt-hour, and a floating-point copy from address 1000h. Integrators need to know which integer register set a given meter uses and how it represents negative values before the numbers make sense. M-Bus versions are managed with M-Bus Master or, for the newer UEM meters, M-Bus Master X, and the software page lists a Modbus Client for UPA analysers that speaks Modbus RTU, Modbus TCP and RTU over TCP. Outside the company, the Belgian energy-management firm Eniris documents reading the UPM209 analyser over both Modbus TCP and RS-485 in its controller documentation.

Measurement and approvals

The UEM80 datasheet and product page give a 20 mA starting current, 80 A maximum, class B active energy to EN 50470-3 on MID models, class 2 reactive energy, 3 x 230/400 to 240/415 V at 50 or 60 Hz and an S0 output at 1,000 pulses per kWh. IMQ, notified body 0051, issued the EU type-examination certificate 226/MID for the UEM80-4D R and UEM80-4D E under Module B of Directive 2014/32/EU.

The UPA30 measures class 0.5S active energy to IEC 62053-22 and complies with IEC 61557-12. The PQM4000 is certified to IEC/EN 61000-4-30 Ed. 3 class A, with harmonics and interharmonics to EN 61000-4-7, flicker to EN 61000-4-15 and IEEE 1453, harmonics to the 63rd, transient capture and Ethernet, RS-485 Modbus and Wi-Fi. PQM Analyzer evaluates the recordings against EN 50160.

Quality systems

The certifications page lists ISO 9001 since 2010, MID type examination and production quality assurance since 2011, class A performance since 2013 and UL listings for the MFC150 and MFC190 coils since 2014, plus UL for the UPA analysers and UL 2808 for the MFC150-UI. ISO 14001 and ISO 45001 followed in March 2025.

Markets

Algodue groups its work into five customer applications. Energy service companies use the analysers for energy diagnoses and efficiency projects. Consumption control and invoicing covers submetering where electricity is billed to occupants: camp sites, shopping centres, residential developments, ports and office buildings, which is where the MID meters and their M-Bus and Modbus versions fit. Retrofitting serves maintainers of existing installations, where Rogowski coils and the RGW smart kits avoid replacing CTs. Renewable energy covers metering of hydroelectric, wind, geothermal and photovoltaic generation. Energy supply quality covers suppliers monitoring grid conditions, including the effects of renewable generation, with the class A analyser.

The company sells in Italian, English, Spanish, French and German from Maggiora, with separate sales and export contacts on its contact page. Much of its output also reaches the market under other names: the customisation service rebrands meters and coils for other manufacturers and develops tailored products and certifications for them. Customers are not named on the company's site.

It describes itself as part of the Socomec Group, the low-voltage power equipment maker based in Benfeld, France, and cites the group's scale for its custom manufacturing. The date of the Socomec acquisition and the size of the business are not published.

History

Algodue dates its founding to 1986. Its certification record traces the growth of the metering business: ISO 9001 in 2010, MID approval in 2011, class A power-quality performance in 2013 and UL listings for its Rogowski coils in 2014. In 2024 it added a 0.5% accuracy class for its coils and a fixing kit that holds them in position for 0.2% accuracy, and in March 2025 it announced ISO 14001 and ISO 45001 certification covering every department.

People and recognition

Leadership names are not published on the company's site. Algodue reported an honourable mention for ethics in social and work environments in December 2024 and exhibited at the BI-MU machine-tool and automation fair in Milan in October 2024, according to its news page.
