Quiet operation is assured as the cooling fan runs only when needed. All models are FCC Class B compliant so the converter is designed not to cause interference with televisions, radios or other signals. Automatic three-stage battery charging maintains your battery's life with three nominal voltage output modes: 13. 2 volt �float� mode, 13. 6 volt �absorption� mode, and a 14. 4 volt �bulk� charge mode. Electronic current limiting automatically shuts down the power during overload or short circuit conditions. Replaces Progressive Dynamics PD9140/45A & PD9245, Parallax 7445, Atwood 45 & Iota DSL-45. Review: Fixed several problems at once - The 3 way fridge quit wworking, carbon monoxide detector wouldn't shut off and auxilliary battery was not staying charged. I pulled the inverter, tested the output and ordered this one. It was simple to install and right away the fridge started working, the alarm shut off (highly sensitive to low voltage) and the auxilliary battery stays charged. The old one was 24 years old when it quit, a bit longer than the usual life, glad an exact replacement was available. Review: GREAT price and OEM equipment for my trailer - Our travel trailer lights (Fleetwood Mallard 290RLS) had been getting dimmer and dimmer and when the AC would kick on, the gas detector would screech due to low voltage. Finally, we switched on the AC one day and nothing happened... we flipped a light switch and nothing happened, we opened the fridge and it was warm inside and no light came on. I bought the WFCO WF9845 12V converter and installed it and voila! Bright, white lights throughout the trailer; the AC came on; the fridge began working again. Life is good now! :) One secret if you have the same trailer as we do, the transformer is NOT located under the fridge as you'd expect, it is next door under a shelf in the bathoom -- still only 2 feet or so from the power distribution panel, but in a different room so it took me a while to find it. Oh yeah, this is a GREAT price. I priced it at 2 different RV dealers in our area (DFW to Waco) and both wanted close to $240 for the exact same unit. Buy it online and you're sure to save money. UPDATE: It is now October of 2015 and the unit is still working perfectly so I can tell you it'll last more than a year, or at least it has for us. ## Features - Quiet operation is assured as the cooling fan runs only when required by the electric load - Fully insulated DC connections are made for protection with an open-top design for ease of use for fast and nearly effortless installation - Product Type: Auto Accessory - Item Package Dimension: 9.29" L x 6.21" W x 3.5" H ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004A35K76 | | Best Sellers Rank | #623,933 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,862 in Power Converters | | Brand Name | WFCO | | Current Rating | 45 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (380) | | Global Trade Identification Number | 00816227010216 | | Included Components | 1 converter | | Item Dimensions D x W x H | 3.5"D x 6.21"W x 3.5"H | | Item Type Name | Arterra WF-9845 45 Amp DC Deck Mount Converter | | Item Weight | 5 Pounds | | Manufacturer | Arterra | | Minimum Frequency | 50 Hz | | Model | WF-9845 | | Mounting Type | Surface Mount | | Part Number | WF-9845 | | Power Source | Battery Powered, Corded Electric | | Specification Met | FCC | | UPC | 816227010216 | | Unit Count | 1.0 Count | | Warranty Description | 1 year | ## Product Details - **Brand:** WFCO - **Current Rating:** 45 Amps - **Mounting Type:** Surface Mount - **Power Source:** Battery Powered, Corded Electric - **Product Dimensions:** 3.5"D x 6.21"W x 3.5"H ## Images ![WFCO Arterra WF-9845 45 Amp DC Deck Mount Converter - Image 1](https://m.media-amazon.com/images/I/81vU6EC4kML.jpg) ![WFCO Arterra WF-9845 45 Amp DC Deck Mount Converter - Image 2](https://m.media-amazon.com/images/I/41FXI43c8WL.jpg) ![WFCO Arterra WF-9845 45 Amp DC Deck Mount Converter - Image 3](https://m.media-amazon.com/images/I/91YscOlsF2L.jpg) ![WFCO Arterra WF-9845 45 Amp DC Deck Mount Converter - Image 4](https://m.media-amazon.com/images/I/81z3-5c0UzL.jpg) ![WFCO Arterra WF-9845 45 Amp DC Deck Mount Converter - Image 5](https://m.media-amazon.com/images/I/41dENy5A8IL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: i replaced the old converter with a 9845 wfco what i need to know isthe three wires that go to the breakers black to breaker green and white go to the** A: Black is the "hot" to the breaker.

The old converter was about 20 years old. Hope this last as long, assuming I still have the camper. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/12715030-wfco-arterra-wf-9845-45-amp-dc-deck-mount-converter](https://www.desertcart.gr/products/12715030-wfco-arterra-wf-9845-45-amp-dc-deck-mount-converter) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-12*
