New technology for functionality and cost effectiveness Unique booster technology providing 5% THDI and PF 0.98 at Input (standard 10%) High efficiency and low accoustic noise Front access only for installation and service EMI filter to comply to EN 62040 Class A Highly competitive footprint and low weight

Standard Booster Technology Battery bank 2x DC Cap 2x IGBT Inverter Rectifier LC filter Mains DC link - DC link + Booster pos Booster neg Through going neutral Batt.Charger T1+ T1- Neutral connection is required Two battery strings of 20 blocks Rectifier is on or off (diodes) There are two DC link voltages Booster is creating a regulated DC link Input neutral = output neutral Battery charger separated from rectifier

separate control for each phase GE’s Unique Booster+ Technology DC link + Rectifier T3+ T2+ T1+ Booster pos Mains 3 phase booster separate control for each phase Neutral T3- T2- T1- Booster neg DC link - Booster for each phase ensuring low input THDI and high input PF (optional)

Input performance Harmonics Feedback Current THDi : <10% Sinusoidal input current waveshape (THD <10%) Harmonics Feedback Current THDi : <10% Power Factor : >0.98 Also at lower load levels Advantages: No additional filters required Prevents need for oversized GenSet Reduced cost for cabling and fusing Input current THD <5% is optional (Booster+ technology)

Energy Consumption Efficiency: 92-94% (double conversion mode) Bypass Supply Static Bypass AC DC Mains Supply DC AC Rectifier Inverter Output Filter Battery Bank The output voltage is newly generated, independently from the input voltage. Voltage and frequency variations at the input are not present at the output. Heat losses are present in Rectifier and Inverter

ECO Mode Supply the load via the bypass circuit in order to prevent heat losses. This can be done only in case the bypass supply is in tolerance Bypass Supply Static Bypass Mains Supply AC DC Load DC AC Rectifier Inverter Output Filter Battery Bank Load is supplied via the bypass The rectifier keeps the batteries charged The inverter is switched off (no heat losses)

Performance of ECO Mode Simulation of transfer back to inverter Fast Transfer to Inverter < 2ms Bypass on/off Output voltage Inverter current Inverter control In case the bypass supply is out of tolerance the inverter will start immediately This transfer is done within 2 ms, which is more than sufficient for most loads Bypass supply voltage tolerance: +/- 10% (adjustable) Bypass supply frequency tolerance: +/- 5% (adjustable) Efficiency up to 98%

RPA Redundant Parallel Architecture LP Series is a cost effective and reliable UPS system, using proven technology To increase system reliability more units can be connected in parallel with GE‘s unique RPA concept RPA features Up to 4 units in parallel Any UPS able to be the logic leader Decentralized bypass No single point of failure Utility Supply To critical load

Back feed protection back feed protection DC AC DC AC Static Bypass Bypass AC DC Mains DC AC Load Rectifier Inverter Back feed protection: preventing feedback to the mains from the inverter in case of mains failure and a fault in the bypass circuit It provides a safer environment for end users and engineers GE provides back feed protection as a standard. Others as option Backfeed protection is mandatory according to EN62040-1 (UPS safety)

Electro Magnetic Compatibility IEC 62040-2 Class A Emission All electronic equipment emits electromagnetic waves through cables (conducted) and air (radiated) Immunity All electronic equipment is sensitive for electromagnetic waves. These waves can disturb the function of this equipment Electro Magnetic Compatibility Different types of equipment (all emitting electromagnetic waves) can work properly even when installed close to each other. They are compatible IEC 62040-2 is a standard that defines the limits of maximum allowable levels of emission of electromagnetic disturbances for UPS systems This certifies the proper functionality of a UPS system and other equipment close to in the environment

Electro Magnetic Compatibility IEC 62040-2 Class A LP 33 complies to IEC 62040-2 Class A Input Output Class A level EMI is a key issue in broadcasting, telecom and other applications where electromagnetic interference exists or needs to be prevented
