GE LP-33U Series UPS

The Digital Energy LP-33 Series is a robust, high-performance UPS system that provides power protection for a wide range of mission critical applications. Every LP-33 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 LP-33 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. The robust design makes it suitable for industrial applications as well.

To achieve redundancy or to increase power capacity, GE’s unique Redundant Parallel Architecture™ (RPA™) technology enables the LP-33 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 outputs and automatically shares the load supported by each UPS.

Features & Benefits

​

• High input power factor (>0.98) and low input THD distortion (<8%) prevents disturbances to other electrical equipment, thus eliminating the need for costly filters or oversized feeders.

• Transformerless design for compact footprint, 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 for oversizing the UPS.

• Intelligent Energy Management in RPA™ Configuration and ECO-mode for single module configuration provides automatic energy savings.

• Superior Battery Management (SBM) enhances battery lifetime resulting in reduced cost of operation.

• Integrated internal manual maintenance bypass reducing the need for external (larger footprint) equipment.

• Fully compliant with standards (cUL: UL1778; IEC 62040, ISO 9001)

• Internal batteries are standard and matching external battery cabinets are available for extended runtime requirements

• Remote monitoring and management available with connections via LAN, modem, SNMP, RS232, Modbus RTU, programmable alarm contacts, and TCP/IP.

• Transformerless design ensures smaller footprint and less weight than transformer technology UPS modules.

• Overload capability @ 125% load on inverter = 10mins. and 150%= 1min.

• Overload capability @ 200% load on bypass = 2mins.

• Output voltage THD @ 100% non-linear load on inverter = <3%

• Output voltage THD @ 100% linear load = <2%
