GE Announces New "Transformerless" Digital Energy™ UPS

GE Consumer & Industrial’s Power Quality business announced its new Digital Energy™ LP-33U Series 10-60kVA Uninterruptible Power Supply (UPS) which is claimed to deliver reliable power protection, an industry-leading 97% system efficiency and proven Redundant Parallel Architecture™ (RPA™) to owners and operators of e-commerce applications, mobile networks, corporate internet sites, medical equipment, banking systems, ePay and networked IT structures.

Available in 10-60 kVA, the Digital Energy™ LP-33U Series’ "transformerless" design and compact footprint are claimed to create less weight, better efficiency, easy front service access, and low audible noise, making it suitable for both office and industrial environments.

GE’s Redundant Parallel Architecture™ technology enables the Digital Energy™ LP-33 Series to parallel up to four units, which is said to cut costs and increase reliability. Controlled in a peer-to-peer configuration using redundancy in all critical elements and functions, RPA™ technology eliminates single points of failure. It precisely synchronizes output phase, automatically sharing the load supported by each UPS.

The Digital Energy™ LP-33U Series UPS is a double conversion UPS system with true online voltage and frequency-independent (VFI) operation. GE’s Intelligent Energy Management™ (IEM) Configuration with ECO mode permanently monitors the quality of the mains, immediately transferring to VFI mode when the mains fall out of tolerance.

The LP-33U Series also: creates a high input power factor (>.98) and low input distortion (<10%) by using a hybrid IGBT rectifier; utilizes Pulse Width Modulation (PWM) IGBT digital technique resulting in low output distortion and fast transient response; remote monitors and manages with connections via LAN, modem, SNMP, RS232, Modbus RTU, programmable alarm contacts, and TCP/IP; and integrates internal manual maintenance bypass, reducing the need for external (larger footprint) equipment and lowering Mean Time Between Repair (MTTR).
