Welcome to M.S. RESISTANCES!

M.S. RESISTANCES is the leading expert
on the High Voltage Resistor market.

Resistor for ice class vessel M.S. RESISTANCES enters the ice class vessel market September 27, 2018

This water-cooled, medium-voltage resistor will integrate the propulsion system of an ice-breaker.

It is designed to absorb 20 MJ and can withstand ± 5 G (80 shocks per minute) and ± 4 G on a frequency range from 25 Hz to 100 Hz.

M.S. RESISTANCES provides resistors for the most demanding applications, including military, ice class and tug boat, as well as the most prestigious cruises or even mega-yachts.

For 9 years, more than 100 vessels can “crash stop” safely thanks to our resistors.

2018-07 CIGRÉ Paris Join us in Paris this August July 13, 2018

M.S. RESISTANCES will participate in the CIGRÉ 2018 exhibition this August in Paris.

Load bank HMI Load Bank HMI innovation September 26, 2017

Our R&D team has implemented a new functionality for our load banks: now, they can be controlled by means of a Siemens HMI. These devices use the most reliable and user-friendly technologies for industrial applications.

From now on, your installation will be monitored in real time: power values, voltage, power factor and temperature can be visualized on dynamic graphs that can also be saved and exported to Excel.

The interface can be adapted following customized requirements, as well as the screen size, log functionalities, remote control requirements ...

New website Welcome on our new website September 26, 2017

After a couple of months of work and planning, we are proud to present our new website!

As you know, the M.S. RESISTANCES team is always looking for better ways to serve our long-term partners and facilitate the exchange between us.

We hope that this new communication tool will allow you to find the information you are looking for rapidly.

Please feel free to tell us if you wish to see more content or if you encounter any problems.

Business meetingM.S. RESISTANCES is present in all the major international projects and will continue to assist you in your realisations.

Calculating and designing a resistor is a task that requires knowledge and a deep understanding of the characteristics of the resistive technology. Most importantly, designing a resistor for 30 or 40 years of service requires a long experience, as it implies being confronted to numerous situations that cannot be apprehended or even defined in specifications.

M.S. RESISTANCES is composed of a team of experts in the field of resistors with an experience that started 30 years ago.

Thanks to this experience, our team of engineers is also able to rapidly understand the requests you may have and provide a timely and appropriate response. This reactivity and quality of the information provided has been recognized and is well appreciated by our partners.

Our objective is to set-up with you a long-term partnership based on competences, reactivity and outstanding service. Please contact us, we will be glad to answer your questions!
