Mitsubishi Electric Automotive America expands vehicle alternator family

Mitsubishi Electric Automotive America has introduced a new member to its family of alternators: the Diamond Power A200 (DP A200) for heavy duty trucks. 

It features many new technologies unique to heavy duty alternators, earning five new patents, Dave Stone, executive director of the company’s heavy duty operations, said.

The DP A200 offers “the highest efficiency rating among major 12V heavy duty alternators in North America, providing improved fuel economy,” added Tony Pantuso, Mitsubishi Electric’s national account manager. It weighs 21.8,  which “is approximately 6.8 lbs, or 24 percent, less than the closest competitor, for improved fuel economy, ease of installation and less front axle weight for increased payload potential.”

The new alternator provides 137 amps of output at engine idle speed. It features “remote-sense” and “5-wire” technology. It has extreme heat tolerance, exceeding all North American OE requirements.

Designed to last more than 1,000,000 miles, the DP A200 includes Mitsubishi Electric’s three-year/unlimited-mile Diamond Gard warranty.

The alternator requires minimal engine horsepower to operate, making it “extremely energy efficient,” Pantuso noted. With less drag on the engine, it “achieves a significant reduction in fuel consumption.”


Long life

The Diamond Power A200 is designed and built to outlive the truck’s original ownership, with major advances in corrosion protection, vibration resistance and heat tolerance, Pantuso pointed out. Battery life is extended with remote sense capability and reduced deep cycling, and by maintaining full output at very high temperatures.

Now undergoing validation trials and field-testing at several OE manufacturers, both the DP A200 and DP A160 (released last year) are currently available for replacement and upgrade applications through regular dealer and independent aftermarket distribution channels in the U.S., Canada and Mexico.

These two PAD–mount, brushless, 5-wire alternators are bolt-in replacements for any existing alternator on all engines with the PAD mount feature. That, Pantuso said, includes nearly all truck-engine combinations manufactured in North America since 2007.

Only one part number for each alternator model ensures minimal inventory requirements for the retailer.

“With the DP A200, we pulled out all the stops in the design department,” Stone says. “It is truly an amazing machine, yet very competitively priced and provides the industry with a new state-of-the-art option.”
