Promariner Debuts ProIsoCharge Series

Marine Charging Systems Leader Announces Intelligent Alternator Power Distribution Systems

Portsmouth, N.H. - ProMariner, an industry leader in the design and manufacture of on-board marine charging systems, introduced today its next generation ProMar Digital Performance Charging platform, the ProIsoCharge Series. An intelligent, zero volt loss battery isolator, the ProIsoCharge digitally controls power distribution of a boat's engine alternator while protecting the integrity of the main engine start battery. The Series can charge up to three independent battery banks from a single alternator. For dual engine applications the new ProIsoCharge offers a 2-alternator input model with up to four battery banks. The innovative ProIsoCharge delivers isolation with no loss in voltage to maximize charging efficiency, ensuring fully charged batteries, faster charge times, and significantly boost reserve power performance for all batteries onboard. ProIsoCharge allows boaters to continue to charge batteries and use the alternator's output to power onboard marine electronics while cruising.

Featuring intelligent digital software monitoring of battery banks and alternators, the ProIsoCharge not only isolates and charges battery banks with zero voltage loss, it also provides priority charging to a battery bank that is under loaded by taking fully charged batteries offline. Unlike traditional diode-based isolators, the all-in-one compact and efficient design eliminates the need for multiple voltage sensitive relays to charge multiple battery banks simultaneously, thus saving boaters space and boat builders cost by significantly reducing installation times. Ensuring the ultimate performance and charging speed, the system eliminates typical alternator voltage loss of up to 0.6 VDC that is also commonly associated with diode-based isolators. All ProIsoCharge models provide an active charging and battery bank status display with a highly visible warning LEDs that illustrate high and low alternator output, over-voltage protection and high voltage conditions that may be present on any one of the connected banks. In addition the alternator's distribution system features ProMariner's innovative Distribute-On-Demand(TM) battery bank management capability, which only activates with ignition power on. The ProIsoCharge is option ready for alternators equipped with advanced regulators.

"The ProIsoCharge line incorporates technology that changes the industry's traditional methods of isolating and charging multiple house & accessory battery banks from single or dual alternators with absolutely no voltage loss," said Gerald (Jerry) Demirjian, partner & senior vice president, ProMariner. "Ideal for larger power, sail and sport fishing boats, our fully-digital, software-based battery isolator ensures boaters' charging systems are optimized for the best, most efficient performance, resulting in longer life battery, maximum battery bank reserve power, and reduced maintenance and replacement costs. Best of all, the technology delivers significant cost savings to boat builders by being a full-featured single product and requiring reduced installation time. When used with ProMariner's new ProNautic P series, boaters can enjoy full charging capability both on the water and while connected to shore power."

The ProMariner ProIsoCharge Series consists of fourteen models named with numerals to denote to the maximum DC amps per alternator input, the number of alternator inputs and battery outputs, respectively. The 12-volt models include the ProIsoCharge120 1o2, ProIsoCharge180 1o2, ProIsoCharge120 1o3, ProIsoCharge250 1o2, ProIsoCharge180 1o3, ProIsoCharge250 1o3 and ProIsoCharge130 2o4. The 24-volt models include ProIsoCharge60 1o2, ProIsoCharge100 1o2, ProIsoCharge60 1o3, ProIsoCharge150 1o2, ProIsoCharge100 1o3, ProIsoCharge150 1o3 and ProIsoCharge80 2o4. Constructed with a modular design for easy installation, the system includes all terminal stud insulator boots and a protective snap on safety cover. The ProMariner ProIsoCharge Series has built-in ignition protection, is dust and water resistant to the IP66 standard and is protected by a 5-year warranty.
