    Product Description
    Float Boost Battery Charger

    The charger works into different modes of operation which are automatically selected between themselves depending on charge condition of battery.
    • Auto-Float Mode : Under this mode of working charger delivers regulated DC output voltage suitable to maintain the battery in Float Charger condition, with variation of main supply voltage as well as output load variation from no load to full load. Adjustment of this regulated voltage is possible by voltage control pre set.
    • Auto Boost Mode : Under this mode of working charger deliver a constant regulated current to the battery while its terminal voltage is in the range of 1.8V to 2.4V/Cell Manual adjustment of this regulated current to the battery is possible by current control trinpot. The terminal  voltage of battery charger builts up as the battery gets charged.
    • In Float cum Boost battery charger automatic mode is provided. Under this mode of working charger works either in auto float or in auto boost mode according to the State of Charger(SOC) of the batteries. Both battery and equipment are connected to the charger. Initially its starts in auto float charging. In this mode if current drawn by battery exceeds a preset value charges a automatically charges from auto float to auto boost mode. As battery picks of charge charging current starts decreasing and charger automatically comes back from auto boost to auto float mode.
