  • Page 11: Introduction

    RPA™ - Redundant Parallel Architecture™ Parallel System ABB provides a unique technology called Redundant Parallel Architecture™ (RPA™) that can parallel Uninterruptible Power Supply (UPS) modules with true redundancy. With RPA™, there is no need for external electronics or switches to control the UPS modules in the parallel system.

  • Page 12: Description

    With Back-feed Protection and compliance to EMC standards the MegaFlex 1000 to 1600 complies to current standards. Reliability can be further increased by paralleling up to six UPS units utilizing ABB’s unique RPA™ technology (Redundant Parallel Architecture). With RPA every UPS is controlled in a true peer-to-peer configuration with redundancy in all critical elements and functions, eliminating all single points of failure.
