The 40-amp WFCO converter transforms shore or generator AC power into the steady 13.6-volt DC your RV batteries require. Three-stage charging automatically selects between float, absorption, and bulk modes, preventing overcharge damage and extending battery life. With 545 watts of continuous output and 680-watt peak capacity, it handles your household electrical needs reliably.

Protection and distribution features include short-circuit and reverse polarity safeguards, an on-demand cooling fan for efficient quiet operation, and built-in AC and DC distribution. Every unit meets FCC Class B compliance to prevent interference with other RV electronics.
