A system for an uninterruptible power supply (UPS) is elementary for data centers: this is the only way to ensure the supply of the center in the event of a power failure. For a reliable UPS, operators of data centers rely, among other things, on modular energy storage systems. As part of its newly developed "Live Swap" certification, TÜV Rheinland is now testing whether such modular energy storage devices can be easily and safely maintained - while the data center is in operation.
Comprehensive error analysis based on international standards
The test catalog for the "Live Swap" certification, which was developed on the basis of globally applicable standards, defines minimum safety requirements that an energy storage system for use in data centers must meet. Among other things, it is about how certain factors can reduce the risk of voltage flashovers or so-called "arcs" and the resulting danger for maintenance workers. The experts from TÜV Rheinland carry out error analyzes and integrity tests on the product design, structure, hardware and software for the live swap certification. Background: Potential hardware errors of the energy storage or the system must not pose any danger to the operator. In addition, the safe and reliable operation of the modular UPS products must be guaranteed.
With its new "Live Swap" certification, TÜV Rheinland goes beyond the basic safety standard IEC 62040-1, which applies to UPS systems. The first products to be successfully tested according to the new certification standard are the "Easy UPS 3-Phase Modular Series" from the French electrical engineering group Schneider Electric.
