Our unique experience and know-how equipped us to develop the OLOP measurement technology utilized in our next generation LKAT systems. Our 8-year effort to develop truly industrialized optical current measurement technology recently yielded our LKCO systems which utilize patented, fully compensated and completely closed loop performance.With over 10,000 systems installed around the world we are the global leader in high power conversion and process monitoring.

We truly understand why energy intensive processes need to increase efficiency, objectively compare multiple plants as well as protect and control power conversion equipment.
