Single Phase GE LP11U Series UPS
LP11U Series Tower UPS
LP-11U Series UPS

The Digital Energy™ LP11U Series is a robust, high-performance UPS system that provides power protection for a wide range of mission critical applications. Every LP11U Series unit operates in a double conversion mode with true on-line VFI (voltage and frequency independent) operation, yielding maximum levels of power protection even under the toughest conditions. In addition, the LP11U Series UPS is easy to install and service, especially in an office environment. The robust design makes it suitable for traditional industrial applications as well.

To achieve redundancy or to increase power capacity, GE’s unique Redundant Parallel Architecture™ (RPA™) technology enables the LP11U Series to parallel up to four (4) units in a flexible and cost-effective manner. In the RPA™ system, every UPS is controlled in a true peer-to-peer configuration, with redundancy in all critical elements and functions. This advanced technology provides the highest possible system reliability for mission critical applications, eliminating any single points of failure associated with other types of UPS systems. The RPA™ system precisely synchronizes the output phase and automatically shares the load supported by each of the UPS.

Every GE UPS system is fully supported by GE’s Global Services team, providing world-class, 7x24 preventive and corrective services, training and application expertise.
