The battery is taking excessively long time to fully recharge
When the charger is powered and is being used as a DC power supply / UPS, the
output voltage drops at lower DC load currents
The unit is in "Half Power Mode". (Green LED (8) located on the bottom left corner of the
front panel of the unit is lighted). When this mode is selected, the maximum charging current
will be automatically reduced to 22.5 A +/- 1 A for SEC-1245A and 12.5 A +/-1 A for SEC-
2425A. Hence, the charging time will increase. Switch off the "Half Power Mode" if the full
rated charging capacity is required.
INTERNAL / EXTERNAL FUSE RATINGS
Both the AC input side and DC output side have fuses.
The AC input side fuse is housed in a fuse holder (10) and is located on the rear panel. It is
rated at 250 V, 12 A, Time Delay (Size 5mm x 20 mm, ceramic tube). Current ratings are as
follows:
•
For operation from 120 VAC input (pre-set) - 12 A
•
For operation from 230 VAC input (will require internal setting) - 6.3 A
The DC side fuses are located inside the unit. To access these fuses, remove the bottom
cover.
These are automotive blade fuses (for example, "Bussmann" Type ATC) rated as follows:
SEC-1245A
SEC-2425A
or
2 pieces, each rated at 32 V, 30 A
2 pieces, each rated at 32 V, 20 A
