50DN+™:  Logical Upgrade Designed for Today's Transit Bus

Today's new transit bus have added inverters, additional lighting, electric cooling fans and electric power steering. They need a more powerful alternator. The Delco Remy 50DN+ provides 450 amps in the package size as the  traditional model. The 50DN+ uses the same 50VR regulator and uses the same oil and vent lines making it easy to switch from the original 50DN. The 50DN+ will provide improved battery life and charging time.
