GE Digital Energy offers the award-winning Intelligent Energy ManagementTM(IEMTM) capability to optimize energy cost while maintaining the highest possible reliability for both single and paralle redundant Uninterruptible Power Supply (UPS) units. For parallel UPS installations, secured with Redundant parallel ArchitectureTM(RPATM), IEM saves energy by dynamically utilizing the UPS modules as needed to meet the required load without compromising on the power quality to the critical load. Use of IEM resulted in incremental savings of up to $33,000 annually for a system of four 100kVA units secured by RPA at full load for 50 hours per week and partial load (10%) for the remaining time. When the quality of the nominal power meets the requirements of the critical load, IEM raises the single UPS efficiency up to 97%. Benefits of IEM include Reduced energy consumption. Maintains power quality and reliability to the critical load. Mains power quality monitoring. User-definable protection levels. Scheduled activation. Additional units switch on automatically in critical situations to increase reliability. Equal operating hours for each UPS in a parallel system.
