Chassis mounting

MBP Series are AC/DC battery charge power converter offered by Mornsun. It features wide input voltage range, taking both DC and AC
input voltage, output over-current, over-voltage protection, strong ability in adapting power grid. This product has power working status
display and Intelligent charging function, it can used to charge the 24V/48V lead-acid battery, when AC is power-off, the battery can
supply power to the load; it has battery activations and over discharge protection function, the activation maintenance of battery can be
done manual or automatic through external signals. Designed specifically for distribution automation terminal (DTU / FTU). It is widely used in
the power industry switch substations, power substation, RMU, Intelligent Package Substation, Intelligent Switch Controller and other
industries which need uninterrupted power supply.
