The Progressive Dynamics Inteli-Power PD9280AV is a 12v 80 Amp 9200 Series RV Power Converter. The PD9280A features the built-in Charge Wizard that offers 4-Stage charging. These four stages are the Boost Mode, Normal Mode, Storage Mode, and Equalization Mode.
The Boost Mode rapidly charges the batteries at 14.4 volts till the batteries reach 90% charged. The Normal Mode finishes the charge cycle by reducing the voltage to 13.6 volts till the batteries are done charging. Once the battery is completely charged the unit switches to the Storage Mode and maintains the batteries at 13.2 volts. The Equalization Mode charges at 14.4 volts every 21 hours for 15 minutes to prevent battery stratification and sulfation.
The PD9280AV includes the Charge Wizard Remote Pendant that plugs into the RV converter. This pendant indicates via an LED light the status of the converter (Boost, Normal, or Storage Mode). It also features an Manual Override button that allows you to cycle the unit through the modes.
