On-line Double Conversion, Intelligent and Heavy-duty, 3-Phase, 50-60kVA UPS
The Digital Energy™ LP33U Series is a robust, high performance UPS system that provides power protection for a wide range of mission critical applications. Every LP33U 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 LP33 UPS is a transformerless, high-efficiency design with low THD (total harmonic distortion), which takes up less space and 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 LP33U 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, 24x7 preventive and corrective services, training and application expertise.

Features and Benefits
-
Transformerless design for smaller footprint, less weight and better efficiency.
-
High input power factor(>.98) and low input distortion (<10%) provided by a hybrid IGBT rectifier, prevents disturbances to other electrical equipment, eliminating the need for costly filters or oversized feeders.
-
Compact footprint, front service access, easily transportable, robustly designed system with low audible noise, suitable for both office and industrial environments.
-
Utilizes high-frequency PWM (Pulse Width Modulation) IGBT digital control technique, resulting in extremely low output distortion and fast transient response, eliminating the need to oversize the UPS.
-
Redundant Parallel Architecture™ (RPA™) increases system reliability by eliminating single points of failure.
-
Intelligent Energy Management™ in RPA™ Configuration and ECO-mode for single module configuration enables automatic energy savings.
-
Fully compliant with standards (UL, cUL, UL1778, CE, IEC 62040, ISO 9001).
-
Very wide AC-input voltage and frequency capability minimizes the need to switch to batteries, resulting in increased battery life.
-
Superior Battery Management (SBM) enhances battery life and reduces cost of operation.
-
Integrated internal manual maintenance bypass reduces the need for external equipment.
