High output marine alternators so powerful that
you can weld with them!
The ZENA® mobile welding system is a new technology, self-contained, ultra-compact, commercial duty, engine-driven DC welder which can be attached to any engine. This 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.
ZENA 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!
This 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 regulator!
Need very high charging current?
ZENA 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.

Need even more power / charging current?
Thanks 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!
The 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:
Unique Design Features Provide Unique Performance Benefits
The 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.
Unlike 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.
A number of features make ZENA power generators different from standard high current marine alternators:
As 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!)
These 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.
Three Year Limited Warranty
ZENA power generators are sold with a three year limited warranty which does not exclude commercial or marine use.
And, our guaranteed overhaul / rebuilding cost policy further insures your investment.
Just try to find a high output alternator anywhere with a warranty -- and/or an overhaul/rebuilding policy like this!
