This Series converter/chargers are versatile, advanced power source solutions. This model provides 75 ampere of clean, reliable DC power, which is ideal for powering electronics and appliances. This 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 this 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.
