New algorithms boost performance of 1600A power cabinet

June 18, 2018 // By Nick Flaherty
ABB has launched a 1600A cabinet design with ETL listing to UL 1008S for its digital static transfer switch (DSTS) product offering using a new digital signal processing algorithm.

The Cyberex SuperSwitch4 is designed with a true fault-tolerant architecture, ensuring there is truly no single point of failure by using patented transfer algorithms and robust electrical components. The power quality detection is immune to harmonics and load imbalance between the phases. In applications with downstream transformers, the SuperSwitch4 limits potential high transient inrush currents using digital signal processors and an algorithm called Real Time Flux Control for dynamic inrush restraint (DIR). This handles out of phase transfers up to 25 percent faster with inrush currents 40 percent lower than the SuperSwitch3. This intelligent proprietary technology ensures performance that exceeds CBEMA and ITIC standards, regardless of phase drift between sources.

With only front access required for installation, operation, and maintenance, the UL 480V design reduces the required floor space by over 50 percent compared to the previous generation. In addition to the reduction in footprint, the 1600A model provides increased containment between the various sections of the system, supporting improved safety and ease of service access.
