WFCO WF9875 Deck Mount 75 Amps Converter Charger

Got this for my RV 12 volt power system and installed myself and saved a ton of money over the dealership price. Easy to install with limited instructions and a basic understanding of power system. Just pay attention to the few connections required. This was the same manufacturer used by most RV parts suppliers.

It would have only taken 5 minutes to change out, if Keystone would have put it, where you could get to it. It works perfect. The picture is of the old one in front of the circuit box. My old camper had the inverter and circuits all in one unit. So, I jump online thinking I need the circuit box and order what looked like it. I thought is was a little cheap for a inverter/Circuit box. Apparently a lot of people make the same mistake, the box the circuit box came in, looked returned 20 times. I hear it a little, if I listen for it. It powers up like the orginal. If not better. A power surge got the old one, along with a furrion fireplace, coffee pot, microwave That inline surge protector, that I though was a waste of money, looks like a bargain right now.

This model failed on my 5 year old RV. So I went out on the interscreen and looked for options. I found this one rated the best value so I purchased the unit because of ratings, value and it is an exact fit for the old one. It is four screws, a ground and the wires to the panel. Installation would be easy for most but my unit is mounted under the oven behind the fuse/breaker panel. It is a logical location but absolutely a booger bear to access. It solved my issue of not charging the battery when on commercial power.I looked at a lot of youtube videos to see if there was a fix for the unit. The only videos out there say, "check the fuses. If they are good check the DC output voltage when the unit is plugged in. If you don't have the 13.6v (or so) replace the unit." OK I replaced the unit. No more than these get used you would think there must be something that is serviceable inside the unit or an easy fix. Oh well, as Ron Washington says, "That's the way baseball go."

It was an exact match for my original part. Easy to install and works!! All I expected.

My 5th wheel is ten years old, it stays plugged at my home. It finally gave up...since the converter board is no longer made for my rig I decided to give this unit a try. My old converter was rated at 45 amps, this unit is rated at 75 amps. It means I had to buy another breaker rated at 20 amps my old one was 15 amps. Lucky had more room in my breaker box for a couple of more. The dimensions for the converter that was given did not reflect the mount which is an extra 1/2 inch taller and about 1 inch extra wider. My breaker box in the lower section contain the converter board. I had to make some serious cuts in the case to make it fit but, it is made of plastic so no problems in cutting it. The other note worth mention here it comes with a 20 amp plug my original converter was hard wired into the breakers. So I made up a new line with a plug on the end so it can be plugged in, for the reason in case I had to return it for warranty. The converter really preforms well it has more power then my old one which started to drop voltage when I turned on the lights in my 31' foot trailer. This one keeps the lights nice and bright, it also has a float charge for the battery, no need to disconnect from shore power for long periods of time in my case a year at least.

As advertised, exact replacement. Mounting flange was slightly bent when I opened the box but was able to be bent back.

This was the same coverter charger which had just failed in my RV. The original lasted 9 years under less than ideal conditions. I have added an extra battery to my unit and this charger is doing double duty. The RV wiring is maxed out with the 75 amp charger so installing a larger charger would require a rewire of the coach's charging system. The deck mount charger is easy to install and not too expensive so I opted for the factory replacement. The cooling fan was the failure mode on the orignal unit. I will probley replace the thermo switch and keep the original for a rebuilt replacement.

This product is a knockoff from the original WFCO.This 9875 converter doesn't have the 20amp input plug as the original WFCO. It's has a 15amp power plug. Does not meet the criteria for a 75 amp output to your RV and other sources.
