If the AC input voltage is correct, the charger is defective. Call technical support
DC SIDE FUSE BLOWS AS SOON AS THE BATTERY IS CONNECTED
Wrong polarity. Ensure positive of the battery is connected to the positive of the charger and the negative of the
battery is connected to the negative of the charger
SYMPTOMS WHEN THE CHARGER IS POWERED AND IS BEING USED AS A DC
POWER SUPPLY
THE VOLTAGE DROPS WHEN LOAD IS SWITCHED ON
The load is trying to draw current more than the current limit value of the charger. Once the load current reaches
the current limit value, the current limit circuit is activated and the output voltage drops. Some loads like motors,
compressors, incandescent lamps, halogen lamps, heating elements, relays, coils, capacitors etc. draw very large
inrush/starting currents, which may reach up to 10 times their normal operating currents. Ensure that the
starting / inrush current or the maximum operating current of the load is lower than the current limit value of the
charger
INTERNAL FUSE RATINGS
Both the AC side and DC side have fuses that are located inside the charger. Disconnect the AC power when
checking or changing the fuses. Open the charger as follows:
1.
Remove the 4 screws on the ammeter side of the top cover
2. Gently slide the top cover out by about 2 to 3 inches. (CAUTION! The top cover will be restrained
from fully sliding out by the wires connecting the ammeter, led and fan
3. The fuses will now be accessible
The fuse ratings are as under:
