PCS120 MV UPS

Next-generation medium voltage uninterruptible power supply designed for multi-megawatt power protection. Based on the revolutionary ZISC architecture, the PCS120 MV UPS offers a flexible solution for higher reliability and greater efficiency in critical power facilities.

The transition from low voltage (LV) to medium voltage (MV) level is a natural progression for power protection in large critical power facilities. This approach offers two main advantages. It increases reliability and reduces the costs of establishing and operating critical energy facilities.

The MV design approach with larger protected load blocks achieves greater reliability thanks to fewer panels and the operational culture of medium voltage systems.

Establishing power protection at MV level provides the most energy-efficient configuration, as the lower currents at this voltage result in smaller cables and lower losses.

Impedance (Z) Isolated Static Converter ZISC

ABB ZISC is a revolutionary high-performance, high-efficiency power conditioning and uninterruptible power supply architecture. It provides protection against a wide range of mains voltage events and continuously supplies clean power.

The ZISC architecture is based on an isolation line reactor combined with high-performance ABB power converters. Supported by advanced control, this simple approach provides unique reliability and performance with class-leading efficiency.

Power converters isolated from the electrical network through an isolation line reactor continuously regulate and filter harmonic and voltage imbalance distribution network issues without requiring energy storage devices to take over. Load-related events such as load-side faults and other dynamic reactive current demands are managed by ZISC’s high overload capacity.
