    RPA™ - Redundant Parallel Architecture™ Parallel System GE provides a unique technology called Redundant Parallel Architecture™ (RPA™) that can parallel Uninterruptible Power Supply (UPS) modules with true redundancy.

  • Page 12: Description

    With backfeed protection and compliance to EMC standards the TLE Series 160 - 500 complies to current standards. Reliability can be further increased by paralleling up to six UPS units utilizing GE’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.
