POWERING OTHER DC LOADS
The charger can be used as a power supply or as a DC UPS (DC Un-interruptible Power
Supply. For both these applications, first set switches S1 and S2 of DIP Switch (5) to off
position to set the charger to work in 2 stage mode (See under "Selecting the Type of Battery
and Charging Stages").
USING THE CHARGER AS A POWER SUPPLY
To use as a power supply, first switch off the DC load. Connect the DC load between the
common negative terminal and one of the 2 positive terminals (either 1 or 2). Ensure that the
maximum current drawn by the DC load is below the maximum current rating of the charger.
Switch on the charger and then the DC load.
USING THE CHARGER AS A DC UPS
In a DC UPS (Un-interruptible Power Supply) , the charger simultaneously powers the DC
load as well as the battery. As long as the AC power to the charger is available and the charger
is working normally, the charger will supply the DC load as well as charge / float the battery.
In case the AC power fails or if the charger stops working, the battery will automatically
power the DC load. As soon as the AC power to the charger is restored, the DC load will
once again be fed by the charger and at the same time the battery will be recharged.
CAUTION! Please ensure that the sum of the current drawn by the DC load and the current
desired for charging the battery is less than the maximum current capacity of the charger.
To use as a DC UPS, first switch off the DC load and connect it to the battery. Now connect
the battery to the charger as explained above under "Charging a Battery outside the Vehicle".
Switch on the charger and then switch on the DC load.
