Product Description


Our WF-8900-AD-MBA Series is a quick, easy replacement part for all power centers that now includes an industry first, Patent Pending Auto-Detect technology. This new microprocessor-driven technology will recognize lithium ion and lead acid battery chemistries and automatically adjust the charging profile to match the battery type. No more buttons. No more switches. RV owners will have the peace of mind that their batteries will be accurately charged, eliminating over and undercharging risks. Additionally, battery life will be maximized with multi-stage charging and current monitoring in both lead acid and lithium profiles. It installs easily with only two screws, three AC wires, and two DC wires. With no need to re-wire, installation is only 10 minutes! Customers also have the option for Reverse Polarity Detection that meets new RVIA & NEC requirements with audible alarm notification. No additional wiring or hookup is required and accepts hi-pot testing.

Replaces the lower power converter section on any WF-8945 Series converter. Installs easily with only two screws, three AC wires, and two DC wires.
