Since its market introduction, Marathon Electric’s MAGNAMAXDVR®

has been a technology leader and proven performer. The MAGNAMAXDVR®

generator line offers as standard a permanent magnet generator excitationsystem with the industry’s first digital voltage regulator.

Each MAGNAMAXDVR® features the exclusive DVR®2000 digital voltage

regulator providing .25% regulation and three phase RMS sensing.

These outstanding features make MAGNAMAXDVR® the ideal generator forvoltage critical applications such as:

• Telecommunication Networks • Hospitals• Airports• Commercial Buildings• Computer Centers

innovat ion,

A proven, top performer in everyrespect, the MAGNAMAXDVR®

generator is a result of MarathonElectric’s fifty years of generatorexperience and an intensive productdevelopment program using cuttingedge technology. Inherent to theMAGNAMAXDVR® design is excep-tional transient performance andstrong motor starting capability.

MAGNAMAXDVR® meets the demandsof today’s changing market offeringreliability and remarkable perform-ance. The MAGNAMAXDVR® supportsa variety of non-linear loads. Typicalnon-linear loads include UPS sys-tems and variable frequency drives.

MAGNAMAXDVR® provides unprece-dented voltage regulation in thepresence of harmonic distortioncaused by non-linear loads.Furthermore, the MAGNAMAXDVR®

low reactance design minimizes theharmonic voltage distortion causedby these loads.

Constructed for extended life,MAGNAMAXDVR® utilizes Marathon’sexclusive unirotor construction,superior class H insulation, and longlife bearings.

Easy access and serviceabilitycombined with Marathon Electric’scommitment to long term supportmake MAGNAMAXDVR® theideal choice for extended life applications.

Permanent MagnetGenerator... ensures 300% shortcircuit current during fault conditionsand provides the regulator with inputpower isolated from load distortions.

Unirotor Construction...incorporates single piece rotor lami-nations, a die cast rotor core andammortiseur windings into an inte-grated rotor assembly. The fieldwinding is wet layer wound to therotor assembly with thermo settingepoxy for high mechanical and elec-trical integrity.

Digital Voltage Regulator...is encapsulated for reliable perform-ance in all environments. The DVR®2000 includes voltage regula-tion to .25%, three phase RMSsensing, adjustable volts/hertzunderspeed protection, advancedengine unloading algorithms, inte-grated paralleling capabilities, andover-excitation/over-voltage protec-tion. A VAR-PF controller is avail-able as an optional feature.

Large Conduit Box... providesample space for easy connectionsand allows load line access from allsides, top, or bottom.

Exciter and PMGMounting... provides easyaccess and serviceability. The PMGis mounted external to the generatorbearing. The exciter is externallymounted on 570 and 740 framegenerators.

Class H Insulation System...utilizes an unsaturated polyestervarnish for optimal insulation lifeand superior moisture protection. A tropical insulation is added forincreased environmental protection.A vacuum pressure impregnatedinsulation system is an availableoption.

Shielded Heavy-DutyBearings... resist contaminationand give a minimum B-10 life of40,000 hours. Regreasing provisionsare available on all generators.

Enhanced Ventilation...created by a high efficiency fan andoptimized internal air flow patterns,maximizes heat transfer and mini-mizes hot spot differentials forextended winding life.

Fully Guarded... for operatorsafety and generator protection, norotating or electrically energizedparts are exposed. All openings are covered by louvers or screens.

Optimized Windings... providelow reactances and exceptionalmotor starting capability. The statorwindings utilize a 2/3 pitch to mini-mize harmonic distortion and facili-tate parallel operation.

Design Specs and Agency Approvals... are impor-tant at Marathon. All MAGNAMAXDVR®

units meet NEMA MG1-22, BS5000,CSA C22.2, IEC 34-1 and VDE 0530requirements. Marine versions areavailable to meet American Bureauof Shipping, Lloyds, Det NorskeVeritas, or Nippon Kaiji Kyokairequirements.
