The WF-9800 Series converter/chargers are versatile, advanced power source solutions. The WF-9845 model provides 45 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-9845 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 VDC 'float' mode, 13.6 VDC 'absorption' mode, and a 14.4 VDC 'bulk' charge mode. Electronic current limiting automatically shuts down the power during overload or short-circuit conditions.
