DC Components DC disconnect (option) is a 2000 A breaker / cabinet (remotely mounted) Same 480 DC Bus (40 cells) as EPS 6000 – may have more cells than others but DC current & cost of ownership is lower!! 90’’ DC DISCONNECT (2000 A) 28’’ 36’’

Easy Installation 6,000 lbs. per spilt Transformer is also front removable & sits on rail assembly Pallet Jack(s) both sides Fork Lift

Output Performance

Fault Tolerant Circuitry Output Performance Fault Tolerant Circuitry A B C Dead short across the output bus will not damage the UPS Wiring changes on the critical bus are common today Other UPS will suffer fatally from output shorts

Precision Voltage Regulation Digital Power Quality Feedback Loop <4% THD even when powering non linear loads A high resolution true sine wave output Prolongs life and avoid premature failure of switch mode power supplies

Optimized For Power Supplies Even in worst cases conditions output remains a pure sine wave Input current of power supplies is limited avoiding overheating distributing the distortion among the critical loads

Output Performance Other UPSs may have sub cycle distortion of 18% on a single phase 100% step load means 0%-100%-0% load (not 50% to 100%)

Efficiency Myths Exposed You said it gets 50 mpg I meant driving downhill CAUTION GENERALIZED STATEMENTS

Interpreting Efficiency w/o input isolation transformer w/ input isolation transformer and filter

Comparing Efficiency MGE maintains efficiency!! Caution: Most published efficiencies not with input isolation or input filter Manufacturers are also subject to best case scenarios MGE Other UPS MGE maintains efficiency!!

Cost Savings YOUR MISSION: Equate operating costs to capital costs $ 0.06 / kWh $ 0.10 / kWh

Easy Maintenance Modular components with low MTTR (mean time to repair) Low MTTR means higher availability –

Easy Maintenance Rapid fan assembly swap Filter replacement w/ UPS on-line Easy viewing of capacitors

No Side or Rear Access 800 kVA 33.0 ft2 Rear view of series 800 No rear access saves: 30 ft2 No side access saves: 9 ft2 800 kVA 33.0 ft2 40 ft2 saved!! Easy front thermal scanning of all components Rear view of series 800 All mechanical electrical bonds are front accessible

Multi-port Communications Interface COMM+2 Card Features 3 communications ports w/o GUI display 2 communications ports w/ GUI display Field retrofittable COMM+2 Serial Port Expansion (adds two ports to EPS 6000) Choose any one option (standard 6000) or add COMM+2 card and choose any three options Dry Contacts (standard) 11 x Dry Contacts (alarms) 9 x Dry Contacts (control) U-Talk / RS232 Port 2 J-Bus (RS232 or RS485) standard Port 3 DB9 Port (standard) Reserved for Field Engineer Diagnostics Port 1 SNMP Adapter Teleservice GUI Display

Communications Protocol MGE Uses J-Bus protocol to communicate with other devices via serial communications links A subset (part) of the most popular for industrial communication protocol Open protocol - most devices have ModBus drivers which usually work for J-BUS Communication registers available from MGE Most building Management and Monitoring system can communicate with MGE Three Phase UPSs

Graphical User Interface Mimic screen Alarm/event log 86 electrical parameters Graphing 96 hour rolling memory

Graphical User Interface Touch screen PC based system - Large 10.2” TFT LCD display Non-critical to UPS operation (standard LCD and controls remain) PC based display using Embedded NT operating system Utilizes MGE Monitor-Pac software One unit can monitor multiple UPSs and SSC’s

12 Pulse Rectifier / Low kVAR Input Filter

Causes of Generator Incompatibility Leading input power factor caused from capacitive content of input filter High kVARs kVAR (amount of reactive power) High input distortion MGE is <12% w/o filter

MGE Stays on the Right Side of the Line!

Generator Friendly Technology Series 800 features: No leading power factor Very low kVAR Low input distortion (5-7%) 100% solid state filter / no hard switching of caps / distortion like load activated filters Permits generator to UPS sizing as low as 1:1 (theoretically) ADVANTAGE MGE

Reliability - The only things that really matters Series 800 credentials: The series 800 is a mechanically optimized EPS6000 All control and PCB’s from EPS 6000 Extensive testing (one year) prior to release Units installed before yours - (15-100) EPS 6000 reliability since 1995 (excellent) No mechanical / contactors in power flow No technology risk “An optimized version of the EPS 6000”
