The WF-9800 Series converter or chargers are versatile, advanced power source solutions. The model provides 65 Amp of clean, reliable DC power, which is ideal for powering electronics and appliances. The 9800 Series provides clean power, even without filtering from a battery. Quiet operation is assured as the cooling fan runs only when needed. Another advantage is FCC Class B compliance for the model, which means that 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 DC “float” mode, 13.6 Volt DC “absorption” mode, and a 14.4 Volt DC “bulk” charge mode. Electronic current limiting automatically shuts down the power during overload or short-circuit conditions.
