WF-9855LiS Deck Mount Converter Charger *

The WF-9855LiS Deck Mount Converter Charger is the first deck mount converter charger in the WFCO lineup designed with a remote switch feature for both lead-acid and lithium-ion batteries. The “remote switching” feature allows for a switch to be installed at any location preferred by the end user. Easy wiring and hookup with a WAGO connection on the back for any switch style. Easy to use, the WF-9855LiS Deck Mount Converter Charger provides a convenient, cheaper, long-term option that eliminates the hassle of swapping out a whole unit. With versatility like this, it’s ideal for use in a wide array of recreational vehicles. The WF-9855LiS Deck Mount Converter Charger provides clean power, even without filtering from a battery. Quiet operation is assured as the cooling fan runs only when needed.

WF-9855LiS Deck Mount Converter Charger is designed not to cause interference with televisions, radios, or other signals. It complies with FCC Class B. Automatic three-stage battery charging maintains your battery’s life with three nominal voltage output modes: 13.2 V DC range “float” mode, 13.6 V DC range “absorption” mode, and a 14.4 V DC range “bulk” charge mode. Electronic current limiting automatically shuts down the power during overload or short-circuit conditions.
