How it Works

The new PD9200 Series RV Converter/Chargers have our patented Charge Wizard built-in to provide you with the most advanced RV battery charging system on the market today. The Charge Wizard is a micro-processor controller that constantly monitors your RV battery voltage and then automatically determines which one of four modes of operation is best suited to recharge or maintain optimum battery condition. The four modes are BOOST, NORMAL, STORAGE and DESULFATION. The Converter Status Remote Pendant will show you which mode the converter is operating in.

The Indicator Light on the Converter Status Remote Pendant will display the mode of operation as follows:

• Light “ON” all of the time – Indicates the unit is in the BOOST MODE and the converter output voltage is 14.4-volts and is in the process of recharging the battery up to 90% of full charge as fast as possible. This mode is usually automatically selected after dry camping

• Light Blinks Rapidly (from once to many times a second) – Indicates the unit is in the NORMAL MODE and the converter output voltage is 13.6-volts. In this mode, the converter is safely completing the charge of the RV battery.

• Light Blinks Slowly (every 6-8 seconds) – Indicates the unit is in the Storage Mode and the converter output voltage has been lowered to 13.2-volts. In this mode the RV battery is fully charged and the converter is maintaining the charge, without causing gassing or water loss.

The Manual Switch...

The Manual Switch allows the operator to check to see if the Charge Wizard is operating properly as follows:

Press and hold the Manual Switch and shortly the Indicator Light will remain “ON” all of the time, indicating the unit went into the BOOST MODE. Continue to hold the switch and shortly the Indicator Light will start blinking rapidly (every 2-3 seconds). This indicates the unit went into the NORMAL MODE. Continue to hold the switch and the unit will go into the STORAGE MODE, and the Indicator Light will start blinking slowly (every 6-8 seconds). Once the switch button is released, the Charge Wizard will again read the RV battery voltage, and after some period of time, automatically select the proper mode of operation.

The Desulfation Mode

The DESULFATION MODE is only active when the Charge Wizard is in the STORAGE MODE. During this mode a timer in the micro-processor automatically switches the Charge Wizard to the BOOST MODE for 15-minutes every 21-hours. This higher voltage causes some slight gassing, and mixes up the battery electrolyte to prevent battery stratification, and the resulting sulfation of the plates, which is the leading cause of loss of battery power.

Note: When no 120 VAC power is applied to the RV through the Shore Power Cord, or Generator, the Indicator Light will remain "ON" at all times. This indicates that the Charge Wizard is monitoring the battery voltage.
