Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Replacement Converter Section for the Progressive Dynamics 4,000 Series RV Power Control Center. Now, this part here will replace the converter section that's on the 45 Amp Progressive Dynamics 4,000 Series and Telepower Converter. This will fit the part number PD4045KA. Now, the power converter will deliver DC power to and to charge your batteries for recreational vehicles, 12 volt lighting and applying circuits. This unit here has a built in charge wizard which is a four stage charging system, constantly monitors the batteries and it'll automatically adjust your converter output voltage based on the battery's charge status.
The converter chargers capable of charging multiple batteries at the same time and it can also charge different capacity batteries at one time. This one here does include a switch to allow charging of lithium batteries. They do have built in features on this to ensure long term reliability. It'll offer electronic current limiting which will automatically reduce the output voltage to prevent overheating. It offers reverse polarity protection which prevents charger damage if your connections are accidentally reversed.
It has high voltage, low voltage protection and it'll prevent damage from AC input voltage fluctuation and it also offers automatic thermal protection which will protect from damage due to excessive heat and also, if you notice right here, you can see it has this variable speed intelligent cooling fan which will only operate under high heat conditions. It is also GFCI protected, helps prevent ground fault interruptions and it is UL listed. Few specs on this unit, input voltage is 105 to 130 volts AC, output voltage is 13.6 volts DC and the wattage on this is 725 Watts, power draw of 45 amps. But, that should do it for the review on this Replacement Converter Section for the Progressive Dynamics 4,000 Series RV Power Control Center..
Thanks for your quick delivery on the PD4045CSV. My installation saved me $330 + what the local RV dealer would have overcharged me to replace it. Thanks to Progressive Dynamics and e-trailer for the easy to replace part.
etrailer - easy to work with, absolute kindness and responsive people not to mention knowledgeable about their products they represent. Have never had an item we purchased that was defective or incorrect. Best advise I can give is pick up the phone and talk to the folks at etrailer before ordering and chances are it will not have to be returned due “wrong part ordered” doesn’t hurt to talk about your project as these guys have already been there and could provide valuable information.

Ordering and shipping was excellent. The converter I received looked to be a previously installed part. Not brand new. I installed it anyway as we were leaving on holidays and could not wait for another one to be shipped out. Time will tell if there are issues. Overall dealing with etrailer was a good experience.
I was excited to get the replacement converter which was needed for my new lithium battery. So much so that I installed it as soon as I received it. The lithium battery was charged to 100% an hour later. Everything went smoothly and the replacement was exactly what I needed. Thank you.
To preface this review, the issue I had with my converter , was that I would get a high-pitched sound that would change tone as different lights were turned on. It was not particularly loud but enough to drive you crazy. The tech team told me my only solution was to replace the converter. The replacement part arrived very quickly and had a simple sheet of instructions with no pictures or other images. Realistically though this is such a very simple fix it really wasn’t necessary for any pictures. Took less than 10 minutes to install. One suggestion I would make if you’re concerned on remembering where the wires go. I simply snipped the wires from the old one and left them in their original position. That way after I swapped the converter it was very simple to see where each wire went and replaced the one at the time. Place everything seems to be quiet.
Installed with ease. I fipped the Li switch on. So far so good. My RV is holding a charge of 14.2, and the battery fuse has not tripped, allowing recharging without my intervention.
Exactly what I needed and it fit perfectly . Daylon was knowledgeable very patient with me when ordering the replacement parts .

That's awesome, David! I'll be sure to let Daylon know, too :)
I have shopped (a lot)via the net for this converter as a replacement. My previous one is not defective but does not have the "voltage bump" for Lithium Batteries. etrailer was the only one that had in the description (picture) the confirmation that it was lithium ready.
The switch was very easy, even though the instructions from the manufacturer are very generic.
Shipment to Canada was straightforward.

Used it between April and November 2025. It works properly in my camper. On one occasion after several days of bad weather. When I finally had shore power, I heard the cooling fan work for one rare occasion I guess the battery charger was sucking up more power. It is not very loud or annoying at all. It was just that quiet where I was, that I could hear it.

My replacement order has arrived fast after the first one lost somehow. It looks good so far. Customer service was so helpful and arranged replacement shipping very fast. Package is well formed and part looks very good and new.

This little replacement converter tray was a perfect idea when faced with the thought of having to pull the entire unit from the trailer. I procrastinated the install because I thought it was going to be difficult, while laying across the RV floor. It was in and hooked up within 15 minutes and began charging the batteries again.
So far so good. Progressive Dynamics puts a tab on the sheet metal so you can't just slide the old one out and the new one in. But it can be worked around.

So far it has been working as promised.
the entire purchase process was perfect. item arrived on time and in good condition. I am very happy so far. I still have to install it in my
RV electrical system.
Just as advertised, timely response and shipping
Works great no more buzzing sound was direct fit for lance 865 also has the lithium battery switch for battery upgrade.
Paper wrap did not keep the item secure since the paper was not wrapped around the converter. The box and bag had damage from the corner of the crt board hitting the inside of the box. I don’t think that this caused damage to the part but showed the “rough” handling by the delivery service.
Replacement part worked as intended
Very easy to install, great instruction s!!
Great price, paid extra for the fast shipping and was delivered on time! Definitely recommend.
I needed this upgraded board to charge lithium batteries. This unit has a dip switch that allows charging of LA or LI batteries.
The installation was very straightforward, the hardest part was lying on the floor to access the power distribution system.
Have to activated it yet, waiting for my battery to arrive.
Remember, if switching from LA to LI, you need to change the on board trickle charger ( this unit) and the solar charge controller.
Very easy to install and it seems to correct the loud hum that I had with the old converter.
Works great with the lithium battery upgrade in my 2011 camper.
I fried the inverter in my camper. Finally figured out which one to order and ordered from Etrailer. It works great! The folks at Etrailer are very helpful and good to work with. Thanks!
It was the correct one. It arrived in a timely manner, consistent with the stated delivery date. It was in perfect condition. And I plan to use y'all the next time a customers part is not an emergency, or I can't get it locally. You'll be the first site I go to. Thank you

The installation was easy and worked well. I have since sold my JAYCO camper so I am no longer using it. The new owner has not contacted me with any issues.
