Frequency converters in stock

We are proud to announce that thanks to the changes in organisation and production technology we have been working on since last year, our frequency converters in the power range up to 200 kW are now available directly from stock. We ship products of higher power rating within 5 days. We thank our team for their hard work and our customers for their continued support. Our customers can now expect even faster delivery times and a more flexible response to their individual requirements. 


The latest result of our development is the NEXIBOOST family of DC-DC converters. It is a platform for customer solutions of non-insulated, bidirectional buck-boost DC-DC converters. They are characterized by high efficiency of 99.5%, currents up to 140 A DC, and voltage up to 1000 V DC.
One of the first applications of NEXIBOOST is the UTNS-01 charger for suspended mining locomotives, which we successfully certified at the beginning of November.


We have also participated in the Middle East Energy 2023, which took place on March 7-9.2023 in Dubai, UAE, where we presented, in addition to our PV COMP and NEXICONTROL PV inverters, also the overall Fuel Save solutions for fuel saving in "hybrid microgrid" networks, which we have been successfully deploying for several years together with our partner P.U.R.E.


We are introducing new PV inverter with non-stop reactive power compensation, PV COMP 350.
