Rated 4 out of 5 by from Great OEM replacement Almost exact replacement for OEM Charger/Converter. Works perfectly. DC connection to DC BUS is a wire gauge smaller than OEM, but obviously adequate for a one foot run.

Rated 5 out of 5 by from PowerMax MBA Perfect Replacement Just what I needed. Perfect replacement for my WFCO MBA. Easy to install. Suggest taking pictures of wiring of old one before removal just to make sure you connect properly. Only downside is that DC power wires are lighter gauge than original. Would prefer they were same gauge as old unit. Multi-stage charging is essential.

Rated 4 out of 5 by from Check the fit, but great replacement to OEM. This didn't fit 100% perfectly. I busted the plastic clip to fit it. But it did fit in the same space as original one and works great. It is keeping my batteries charged!

Rated 5 out of 5 by from Works Fits in the OEM slot just like it was supposed to. Easy to install, works properly, I cant hear the cooling fans as I noticed others write it was loud.

Will this unit work as a standalone charger for a deep cycle battery in a cargo trailer? If not, can you point me in the right direction?

Asked by: Dustin
I have installed this on my travel trailer. There's no reason you can't use it as a standalone charger.

Will this convertor replace my old Centruion3000 unit

Asked by: Charlie
No, a Centurion CS 3000 does not have a dedicated lower section like a larger power center does and is what SKU#95474 is designed to be installed in. Due to the lack of parts for a CS 3000, it is recommended that it be replaced by a WF-8735 power center from WFCO. We have this unit listed as SKU#86727
