The WFCO WF-9800 Series Converter/Chargers are versatile, advanced power source solutions. The WF-9855 model provides 55 amps 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 WF-9855 model, which means that the converter does not 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 VDC range "float" mode, 13.6 VDC range "absorption" mode, and a 14.4 VDC range "bulk" charge mode. Electronic current limiting automatically shuts down the power during overload or short-circuit conditions.
