ince its market introduction, Marathon Electrics
MAGNAMAX
DVR®
has been a technology leader and proven performer. The
MAGNAMAX
DVR®
generator line offers as standard a permanent magnet generator excitation
system with the industrys first digital voltage regulator.
Each
MAGNAMAX
DVR®
features the exclusive DVR
®
2000 digital voltage
regulator providing .25% regulation and three phase RMS sensing.
These outstanding features make
MAGNAMAX
DVR®
the ideal generator for
voltage critical applications such as:
Telecommunication Networks
Hospitals
Airports
Commercial Buildings
Computer Centers
i n n o v a t i o n , A
proven, top performer in every
respect, the
MAGNAMAX
DVR®
generator is a result of Marathon
Electrics fifty years of generator
experience and an intensive product
development program using cutting
edge technology. Inherent to the
MAGNAMAX
DVR®
design is excep-
tional transient performance and
strong motor starting capability.
MAGNAMAX
DVR®
meets the demands
of todays changing market offering
reliability and remarkable perform-
ance. The
MAGNAMAX
DVR®
supports
a variety of non-linear loads. Typical
non-linear loads include UPS sys-
tems and variable frequency drives.
MAGNAMAX
DVR®
provides unprece-
dented voltage regulation in the
presence of harmonic distortion
caused by non-linear loads.
Furthermore, the
MAGNAMAX
DVR®
low reactance design minimizes the
harmonic voltage distortion caused
by these loads.
Constructed for extended life,
MAGNAMAX
DVR®
utilizes Marathons
exclusive unirotor construction,
superior class H insulation, and long
life bearings.
Easy access and serviceability
combined with Marathon Electrics
commitment to long term support
make
MAGNAMAX
DVR®
the
ideal choice for extended life
applications.
Permanent Magnet
Generator...
ensures 300% short
circuit current during fault conditions
and provides the regulator with input
power isolated from load distortions.
Unirotor Construction...
incorporates single piece rotor lami-
nations, a die cast rotor core and
ammortiseur windings into an inte-
grated rotor assembly. The field
winding is wet layer wound to the
rotor assembly with thermo setting
epoxy 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 RMS
sensing, adjustable volts/hertz
underspeed protection, advanced
engine unloading algorithms, inte-
grated paralleling capabilities, and
over-excitation/over-voltage protec-
tion. A VAR-PF controller is avail-
able as an optional feature.
Large Conduit Box...
provides
ample space for easy connections
and allows load line access from all
sides, top, or bottom.
Exciter and PMG
Mounting...
provides easy
access and serviceability. The PMG
is mounted external to the generator
bearing. The exciter is externally
mounted on 570 and 740 frame
generators.
Class H Insulation System...
utilizes an unsaturated polyester
varnish for optimal insulation life
and superior moisture protection.
A tropical insulation is added for
increased environmental protection.
A vacuum pressure impregnated
insulation system is an available
option.
Shielded Heavy-Duty
Bearings...
resist contamination
and give a minimum B-10 life of
40,000 hours. Regreasing provisions
are available on all generators.
Enhanced Ventilation...
created by a high efficiency fan and
optimized internal air flow patterns,
maximizes heat transfer and mini-
mizes hot spot differentials for
extended winding life.
Fully Guarded...
for operator
safety and generator protection, no
rotating or electrically energized
parts are exposed. All openings are
covered by louvers or screens.
Optimized Windings...
provide
low reactances and exceptional
motor starting capability. The stator
windings 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 MAGNAMAX
DVR®
units meet NEMA MG1-22, BS5000,
CSA C22.2, IEC 34-1 and VDE 0530
requirements. Marine versions are
available to meet American Bureau
of Shipping, Lloyds, Det Norske
Veritas, or Nippon Kaiji Kyokai
requirements.
