1.) What makes Balmar alternators and regulators so special? - Very frequent question & response from Balmar

In order to really understand the difference between Balmar charging equipment and the average alternator and regulator, it's important to understand Balmar's goal in designing and building alternators.

In an automotive application, the alternator's function is to keep a starting battery happy while supplying power to electrical/electronic operations needed to operate the vehicle (i.e., headlights, cassette deck, vanity mirror lights, 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 fulfill 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 durable frame, that's protected against potential corrosion damage. Balmar applies a durable powdercoat finish to protect the alternator from rust and corrosion.

Another thing that sets a Balmar alternator apart from the rest, is the technology Balmar uses to create rotors and stator windings. The rotor/stator combination is the primary factor in controlling the amount of top-end output, low-end output and cut-in level (how slowly the alternator can turn and still make useable amperage). The rotor and stator combinations in Balmar's alternators are custom wound and calibrated to maximize output, not just at top end, but also at the low end of engine rpm.

But, that's just half the story ...

Balmar has been one of the industry leaders in creating intelligent voltage regulation that enables them to meet the needs of newer battery types, and the added load that modern electronics and inverter technology demand. Intelligent regulation, like that provided by Balmar's Max Charge regulators, matches the output of the alternator 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 constructions, and they can most effectively utilize the added capabilities that Balmar's alternators provide. And they did it in a way that doesn't require the end user to be an engineer to get the most out of their charging systems.

In addition, Balmar's Max Charge voltage regulators are equipped with the ability to monitor both battery and alternator temperature, and respond by increasing or decreasing voltage levels 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. These systems are really very smart.
