Micronics Systems has been designing, assembling and maintaining DC rectifiers, regulated power supplies and generators for industry in France since 1989. Thirty-five years on, the company is still based in Isère, in Villette-d'Anthon, and still builds its equipment on site.
It all begins in 1989 in Chavanoz, with a simple conviction: the quality of a surface treatment or of a laboratory test depends first of all on the quality of the current fed into it. Two years later, Micronics brings the first French 1,000 A – 12 V switch-mode rectifier to market. Switch-mode changes everything: for the same power, the unit becomes more compact, more stable and more economical than a conventional solution.
The following decades broaden the business without changing it. Regulated laboratory power supplies in 2000, 100 kW generators and the Powerswitch series in 2004, converters and inverters, then scalable modular cabinets. In parallel, the company builds what sets it apart today: an in-house engineering department that sizes equipment from the customer's process, a workshop where every unit is tested before dispatch, and a department dedicated to repair and maintenance.
Today, MicronX rectifiers power surface finishing lines — zinc plating, hard chrome plating, anodising, precious metals — and test benches in aerospace, automotive, nuclear and research. Up to 6,000 A, always designed and assembled in Villette-d'Anthon.
A small Isère company betting on the switch-mode rectifier, at a time when industrial power was still mostly controlled another way.
The company is born in Chavanoz, Isère, around one idea: designing industrial power sources in France.
Launch of the first 1,000 A – 12 V switch-mode rectifier on the French market: more compact, more accurate and more economical than a conventional solution.
R&D becomes the engine of the company: it is what still allows us today to answer the specification rather than the catalogue.
An office opens in the Paris region and the first international business develops, which will grow to as much as 30 % of turnover.
The catalogue expands from the surface finishing rectifier to the regulated laboratory power supply, and the production facility follows.
Creation of the department dedicated to regulated power supplies, which will give rise to the Microlab range.
The company moves to its current site, 18 rue des Émeraudes, 25 minutes from Lyon.
First 100 kW switch-mode generator (5,000 A – 20 V) and launch of the Powerswitch series, designed for high power in cabinet format.
Extension to DC-AC and DC-DC converters with the Powerlab series.
Inverters, converters, sources and loads: Micronics now covers most controlled-power requirements.
A larger production facility, a dedicated after-sales department and a test laboratory: the company organises itself to support customers over the whole life of the machines.
Expansion of the production facility in Villette-d'Anthon: wiring, assembly and testing all stay in-house.
The company builds a technical sales team, able to size equipment together with the customer.
First developments of Twin technology, which allows two sources to work together.
Micronics sets up a subsidiary to support its growth.
Launch of the service business: workshop repair, on-site intervention, spare parts and preventive maintenance.
Marketing and sales activities are reinforced, with a stronger presence at industrial trade shows.
Opening of a laboratory dedicated to advanced surface finishing technologies, to test processes together with customers.
A major step forward on modular cabinets: a scalable architecture, from 16U to 43U.
The rectifier is no longer just a current source: it is a connected, programmable, supervised piece of equipment.
Twin technology reaches its full duplex form.
Touchscreen HMIs become standard: setpoints, ramps, ampere-hour counters, polarity reversal cycles and remote control.
Three roles Micronics has taken on from the start, and has never outsourced.
An in-house engineering department designs every solution from the specification: voltage, current, cycles, control mode, installation constraints. Bespoke is not an option, it is the default way of working.
Wiring, assembly and testing are carried out in our workshops in Villette-d'Anthon. 100 % of units are tested before dispatch — that is the step that guarantees a rectifier will hold its values on the day it is commissioned.
Because we designed them, we know how to repair them. Preventive maintenance, workshop repair, spare parts and on-site service extend the life of the equipment well beyond the warranty.
