![]() No Load DC Output Voltage: 13.6 VDC ±.Maximum Continuous Input Power: 550 Watts.WFCO 8735 Works In Vehicles that PD4135KW2B works in This Product Replaces These Other Products & sulfation – the leading cause of battery failure. EQUALIZATION Mode 14.4 Volts – Every 21 hours for a period of 15 minutes prevents battery stratification.STORAGE Mode 13.2 Volts – Maintains charge with minimal gassing or water loss.NORMAL Mode 13.6 Volts – Safely completes the charge.BOOST Mode 14.4 Volts – Rapidly brings RV battery up to 90% of full charge.The Progressive Dynamics PD4045KV is a 35 Amp distribution panel/converter system.Īvailable with Progressive Dynamics exclusive built-in Inteli-Power Converter…”The most reliable converter in the RV industry”. The converter section is easily servicable. The AC Distribution Panel is rated for 120 VAC 30 Amps with up to 5 branch circuits. The DC section has 6 branch fuse holders, with a maximum rating up to 30 Amps each. The Inteli-Power PD4135 can recharge the battery to 90% in approximately 3-6 hrs using their patented Charge Wizard Technology. Progressive Dynamics 4100 Series AC/DC Distribution Panel & Power Converter with Built-In Charge Wizard is a direct replacement for the WFCO 8735 RV converter. ![]() No other changes were made between model numbers. Both part numbers are the same unit model a letter was added to the model by the manufacturer. Note that the DC power for the Isolated Circuits is always coming directly from the battery or the charging circuit when 120 VAC power is applied to the RV (green arrows).Important Notice Customer may receive unit with part number "PD4135KW2B" or "PD4135KW2BV". This action also disconnects the RV battery from the branch circuits and places it on charge (blue arrows). Now the converter feeds DC Power to the branch circuits (red arrows). This DC power is also fed to the Relay Coil, which in turn pulls down the center arm of the Relay so that it makes contact with the lower N.O. It is then fed through the Diode Rectifiers, which convert this AC Voltage to 13.8 VDC. Both are used on smaller trailers - there are 6 half-size AC circuit breaker slots, and 6 fused DC circuits. That's why the PD 4135 is a complete panel/converter replacement also. I sure couldn't find it if it does exist. The Transformer reduces the 120 VAC down to 13.8 VAC (Alternating Current). The OEM WFCO8735P does not have a way to replace the converter separate from the panel. The Isolated Circuits for the Radio, TV or Stereo are connected directly to the battery positive terminal. See figure 2 below for operation when AC power is applied. The RV battery is supplying 12-volt power (Red Arrows ) to the RV branch circuits through the N.C. This resistor limits the amount of charging current that can be delivered to the battery. It is turned ON when the battery needs charging current and is turned OFF, when the circuit board senses the battery is charged. This is basically an electronic switch that is controlled by the circuit board. ![]() Very Slow Flashing Light: When the light blinks approximately every 5-10 seconds, the battery is fully charged.Rapidly Flashing Light: The battery is approximately 90% charged. ![]() Light "ON" all of the time: The battery is being charged.The charger board is equipped with an LED (Light Emitting Diode) that indicates the charging status as follows. Senses the battery voltage and then provides a signal to the SCR (Silicon Controlled Rectifier) to turn it ON, which in turn supplies charging current to the RV Battery. Reduces the 120 VAC from the Shore Power or Generator down to approximately 13.8 Volts AC (Alternating Current) at its secondary output.Ĭonverts the 13.8 Volts AC from the Transformer secondary output to approximately 13.8 Volts DC (Direct Current).Īutomatically disconnects the RV Battery from the 12-volt RV circuits and then connects the 13.8-volt power to the RV 12-volt circuits when Shore Power is connected to the RV.
