High output marine alternators so powerful that
you can weld with them!
mobile welding system
is a new technology, self-contained, ultra-compact, commercial duty, engine-driven
DC welder which can be attached
to any engine.
welding system uses a unique, modular, electrically isolated DC welding power generator,
which is built by ZENA, Incorporated, in the USA, to withstand the extraordinary
stresses of high current welding in severe operating environments.
But, that's not all!
While it's definitely NOT a standard
alternator, in addition to generating DC welding current, a ZENA®
DC power generator can
also be used to:
a standard marine alternator in diesel powered vessels, or to
(or be used as) a secondary alternator dedicated to charging/maintaining secondary
battery banks, or to
as a part of a high output, heavy duty, high current battery charging system,
an onboard DC power source for large non standard electrical loads such as
exotic sound systems, communication systems,
or computer systems,
- as the key component in an ultra-compact custom DC genset application
power generators/alternators are designed for external regulation -- and are
designed to be completely compatible with ALL types and brands of heavy duty (8-10A
rotor current) external voltage regulators!
means that you can take advantage of a wide range of alternator control systems
ranging from simple, automotive voltage regulators to the most sophisticated multistage
and/or programmable voltage regulator units/systems on the market -- including the
line of highly specialized and sophisticated regulators that we have designed to
take maximum advantage of all of the capabilities and features built into our ZENA
power generators! And, it also means that you can probably replace your existing
alternator with a ZENA unit without the expense of replacing your existing external
very high charging current?
power generators/alternators are also designed to work as secondary alternators dedicated
to charging a large secondary battery bank -- or supplying power for other nonstandard
electrical loads. Used in this way, your engine starting battery and stock alternator
can be left in place -- operating as they were designed to do -- insuring the integrity
of key operating/safety systems.
about choosing a high current alternator,
then take your choice from:
150 amp @ 13-22 VDC welding power generator/high-amp alternator (model SR150.12 --
our most popular model); or
200 amp @ 13-22 VDC welding power generator/high-output alternator (model SR200.12);
- a 250 amp @ 13-22 VCD welding power
generator/high-output alternator (model SR250.12); or
80 amp @ 24-36 VDC high-amp alternator (model SR150.24); or
125 amp @ 24-36 VDC high-output alternator (model SR200.24); or
140 amp @ 24-36 VDC high-output alternator (model SR250.24)
Modular Power Generators/Alternators
Powerful Marine Battery Charging Systems
even more power / charging current?
to unique construction features and our unique electronic control system, multiple
power generating units/alternators can be attached to the same engine, or multiple
engines -- controlled and used together -- just as if the individual generators were
a single giant alternator!
Specifically designed for use in this manner, with the appropriate control accessories,
ZENA's modular power generators/alternators can be used in synchronized groups
to efficiently produce very high, well regulated battery charging currents -- from
150 to over 1,200 amps., in 12 volt systems -- and over 750 amps in 24 volt applications!
use of multiple generators on a given engine, strategically mounted (for example
on opposite sides of an engine) can also serve to remove side loading stress from
engine bearings while still allowing the installation of a large charging system.
Typical charging/DC generating systems include:
300 amp* @ 13-22 VDC multiple alternator generating system;
400 amp* @ 13-22 VDC multiple alternator generating system;
500 amp* @ 13-22 VDC multiple alternator generating system;
600 amp* @ 13-22 VDC multiple alternator generating system;
800 amp* @ 13-22 VDC multiple alternator generating system;
1000 amp* @ 13-22 VDC multiple alternator generating system; or
charging systems can easily be configured!
(* power output, in amps, in 24-36V electrical systems will be less -- though
wattage produced will be comparable)
Design Features Provide Unique Performance Benefits
typical alternator is just not built like a ZENA DC power generator (a key reason
why we make this distinction rather than referring to them simply as alternators).
Therefore, if quickly charging batteries is important, a ZENA power generator
is an ideal solution.
standard high-amp alternators most of which are designed to produce high currents
for a relatively brief period, a ZENA power generator/alternator has been built
to produce higher currents continuously --- an absolute necessity for welding,
and also a great feature for big charging jobs.
number of features make ZENA power generators different
from standard high current marine alternators:
power generators are designed so that they can be controlled with either A or
B Circuit (type N or type P) external voltage regulators, or with ZENA's model
WC.VR voltage regulator and WC.12 or WC.24 multi-generator controls.
heavy duty output terminals are fabricated from silicon bronze (almost pure copper,
but more durable) to insure minimal corrosion in marine environments as well as minimal
electrical resistance to the huge charging currents that ZENA power generators can
produce (many alternators use high resistance, easily corroded, mild steel terminals
on their alternators). AND, these oversize bronze terminals are no less than 5/16"
in diameter at any point -- capable of easily handling much larger charging currents
-- unlike many so-called high-amp/heavy-duty alternators which only appear to have
heavy duty output terminals while internal current handling components are actually
output is completely isolated electrically from the generator/alternator case
(and, therefore, from the vessel's ground plane). When connected to take advantage
of this feature, high amp alternator charging currents can flow directly to the
batteries WITHOUT having to also pass through hull or fittings. This feature
also makes connection of generators in series parallel combinations possible.
field circuits are also completely isolated electrically from the generator/alternator
case (and, therefore, from the vessel's ground plane) enabling special regulation
systems to be implemented without modification.
in all ZENA power generators/alternators are more than double the size required to
handle rated output currents, and are also capable of handling exceptionally
high reverse voltage spikes. Rectifier heat sinks are equally robust allowing
reliable high amp operation in exceptionally hot operating environments.
For example, in our SR200 series, which is designed for exceptionally duty, we use
twelve (12) individual rectifiers (double the amount found in a typical alternator)
-- mounted on double solid copper heat sinks in a separate cooling compartment isolated
from the hot internal generating components. (This provides most of the benefits
found in an externally rectified alternator without requiring extra engine compartment
mounting space or requiring a more complicated installation or extra wiring.
are oversize, and much higher quality than found in a typical alternator -- equally
capable of handling high side loads and high temperature operating environments.
For example, our 200A alternator's front bearing is large enough for use as a wheel
bearing on a small utility trailer!
- To further reduce bearing wear, and increase service life, rotors are spin balanced
and machined to ultra close internal tolerances.
wiring, including stator and rotor windings is extra heavy duty -- oversize (stator
wire is so large in diameter that windings must be carefully hand fitted to stator
laminations), and designed with an insulating system capable of withstanding temperatures
of more than 150 degrees Celsius (over 298 degrees Fahrenheit) without failure.
magnetic materials (stator laminations and rotor poles) are built from alloys specially
selected for superior magnetic properties.
you might guess, none of these design/construction features have been selected because
they are inexpensive. However, cutting costs on items that contribute to product
reliability is not something that we do. In fact, our employees get more reward
for finding parts with superior performance, reliability, or service life than they
do for finding cheaper parts! (In our opinion better quality costs much less
than a huge customer service department!)
features do not, however, repeal any laws of physics, nor do they eliminate the necessity
to follow good charging system design parameters. You should not scrimp on the selection
of proper voltage regulation and/or system protection components for a given application
-- nor should you ignore over temperature protection, manufacturer's recommendations
for charging current/voltage, proper fusing, charge current limiting/monitoring during
bulk charge, etc. These considerations are especially important if your are planing
to charge a large battery bank (particularly a large AGM battery bank -- or battery
banks made up of a more than three individual batteries wired in parallel) with a
relatively small generating system. Such a system would be defined as one where battery
capacity in amp-hours (AH) is more than twice the continuous charging capacity
of a given alternator in amps. An example of this would be a 200A alternator being
used to charge an 800AH battery bank.
