SYMPTOMS WHEN THE CHARGER IS POWERED AND IS BEING USED AS A
DC POWER SUPPLY / UPS
THE VOLTAGE DROPS WHEN LOAD IS SWITCHED ON
The load is trying to draw current more than the current limit value of the charger ( the current limit
value is the maximum specified charging amps ). 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 sides 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
