Uninterruptible Power Supply
Reference Installation
Fuel cell system as a substitute for a conventional uninterruptible power supply with batteries.
The system is based on the Heliocentris Nexa® 1200 fuel cell module.
An integrated, highly-efficient DC/DC converter, specially developed for the Nexa® 1200, generates a regulated system voltage of 24 VDC, which is buffered by a small battery. All components are integrated in an indoor enclosure. The overall system control and the data recording take place through the Heliocentris Nexa® OSC software.
The system was tested extensively over a period of six months for both short-term and long-term operations. Additional tests dealt with energy efficiency, overloading and serviceability.
The suitability of the Nexa® 1200 system program for the realization of industrial emergency power supply has been successfully verified.
