What makes ZRD Manufactured Alternators so Special? |
|
In order to really understand the difference between a
total system designed ZRD HIGH OUTPUT ALTERNATOR and the average alternator, it's important to understand ZRD's goal in
designing, manufacturing, and assembling alternators.
In the typical automotive application, the alternator's function is to keep a starting battery recharged after engine start and then supply power to electrical demand needed to operate the vehicle (i.e., headlights, radio, engine, etc.). In this environment, a simple, internally-regulated alternator is usually more than sufficient to get the job done. In the marine environment, the alternator and regulator must support a much greater battery capacity to satisfy engine and house battery loads. The alternator and regulator must also be able to charge effectively at lower rpms and live in an inhospitable environment. In addition, the alternator and regulator may sit for long periods between uses (surprisingly, one of the toughest aspects of alternator life). At the same time, this system must meet the expectations of boaters that want to have their batteries charged within the least amount of engine run time. To meet those challenging conditions, a high-output marine alternator begins with high amperage diodes, larger, higher-quality bearings, and a dedicated ZRD designed DIRECTIONAL COOLING FAN for clockwise or counter-clockwise rotation. Special Note: ZRD manufactured High Output Alternators have a dedicated, engineered, cooler running design that lowers the alternator temperature apx. 35 to 50 degrees compared to other alternators brands. This ensures longer life, higher output, and better performance. ZRD frames are protected against potential corrosion damage by applying a durable powder coat finish to protect the alternator from rust and corrosion. Combining a totally designed ZRD High Output alternator containing a dedicated directional cooling fan with an external regulator, the alternator's output is matched to the specific needs of your batteries (AGM, gel, Optima, deep-cycle flooded, etc.) so batteries charge faster based on the needs of their unique construction. In addition, an external voltage regulator is equipped with the ability to monitor both battery and alternator temperature, and respond by increasing or decreasing output in order to maximize both safety and performance. In the event of a condition that poses danger to the system or the vessel, the regulator has the ability to discontinue charging completely. |
