About Us

DC Pioneers

Dating back to early 2000 we started direct current research at the new company Netpower Labs, the team had long experience from designing Telco 48V systems at Ericsson. For a short time Ericsson even had a microgrid system that combined PV, Wind, battery storage and a mini-diesel backup, everything 48V.

As we realized that a 230Vac switch mode power supply could be fed with AC as well as 350Vdc our work to develop a UPS system with better energy efficiency, lower component cost and higher reliability started.

It took us some years as a lot of ground work had to be done, searching for DC specified components, testing of connectors, fuses and cables etc. The product portfolio rapidly grew as there were no 350Vdc products on the market, so we were forced to develop them ourselves.

In 2006 we did our first real installation with our new DC UPS, a server rooms and telephone system in the small city Gnesta just south of Stockholm. In the beginning we were focusing on small ICT installations with a few servers and a PBX (small private phone exchange).

In Generation 2 we increased the power and were looking for datacenter customers, we made installations in several datacenters around the world and also sold test systems to large corporations like Ericsson, France Telecom and NTT.

In Generation 3 we added PV solar energy to the system. With a 99% energy efficient PV converter and our NetTracker® technology we made lots of installations, from datacenters via cable TV networks to office installations, everything running on DC.

Today we are very proud of the Generation 4 of the DC portfolio, all our converters are FW based with fancy components like SiC/GaN transistors and high-end inductor cores.

Our unique Dual Converter™ technology gives world-leading energy efficiency and all power converters can be controlled using the same Modbus communication link. Thanks to the FW controlled converters things like Droop Control and voltage curves can be set on the fly without interruptions.
