About us

Safe and reliable control solutions for decentralised power production, marine & offshore and wind turbines.

Empower your business for the energy transition

The energy sector is in transition, affected by the need to move from fossil fuels to renewable sources. Technologies change. Regulations change. We must broaden our perspective and adapt to new and more  sustainable practices – the faster the better. Setting some of the highest standards in power management and protection, we are well-suited to meet the market requirements of tomorrow. For us, the key is to provide a full line of electronic devices that are not only reliable and compatible but also ensure the highest flexibility, always making it possible for customers to pick and choose the hardware and software that matches their needs.

This, together with our leading application knowhow, our global presence and local assistance, enables our customers to become both more agile and resilient towards change. This is shaped by our DNA. As a family-owned and independent company, we believe in close and honest long-term collaborations, and as engineering experts, we are grounded in creating persistent, relentless improvement in our products and solutions. Setting standards has always been part of who we are. With the ambition to enter new territories, we are set to empower all integrators, OEMs, and asset owners that have sustainability in mind, continuously providing control devices and systems that not only grow business but more than anything – Improve Tomorrow.
