MSM (High Freq Charger)

The MSM Series is a High Frequency Switch Mode charger specifically developed for Marine applications. MSM series incorporates Power Factor Correction (PFC) Circuitry with a wide input voltage range in order to accommodate many marine charging applications. The MSM has an Integrated Battery Charge Divider / Isolator which provides connections for charging up to three independent batteries simultaneously with a three-stage charge cycle. MSM’s filtered output is suitable to charge different types of batteries for Marine/Industrial applications. This series is equipped with an LCD display for ease of navigation through the configurations menu. The LCD also displays Input AC voltage, Output DC Voltage & Current, and Alarm Status. The front of the unit provides three status LED indicators for the overall status of the system. The MSM charger is built in a robust, non-corrosive enclosure that addresses harsh Marine environments, meeting stringent safety and regulatory standards.
