The Imperium IMP009 50A AC-DC smart battery charger uses the latest
switch-mode technology for charging AGM / lead-acid batteries. The automatic 7
stage charging algorithm delivers a more efficient and full charge without the
issue of voltage drop. The boost-charging feature activates the battery status and
will wake up a weak or flat battery to get it to a suitable recharging level, which
improves the charge delivered to your battery, increases the service life of battery
and prevents premature battery failure.
This smart battery charger can also be used to charge GEL AGM/ WET batteries by
pressing the mode selection button, and as a constant power supply (orange LED
or red LED) to run devices that require a stable and clean DC voltage.
When charging lithium batteries, you must set the charger to lithium battery
charging mode by pressing the MODE SELECTION button until you see the LED
turn green. The LCD will display charging voltage , charging current and charging
stage.
For safety reasons, the input and output of the charger are completely isolated
and the batteries are protected from being overcharged.
The internal cooling fan is thermal & charge current dual controlled, activated
when the temperature reaches 45 degrees centigrade or when the charge cur-
rent is 2A. The fan will automatically switch on and off to control the internal tem-
perature of the unit.
This smart battery charger must be connected to a battery before the DC output
starts to activate. Note: this is a touch-type battery charger and the battery volt-
age required for constant current mode is 12.6V.
Protection features:
DC short circuit protection: if activated the charger will automatically cut off
the DC output immediately. The LCD will display "- P-" and the battery charger
will reset automatically once the short circuit fault has been remedied.
Over heat protection: if the internal temperature reaches 75 ± 5 °C the LCD will
display "-P-". When the temperature drops back down the battery charger will
reset automatically.
