Internal / External Fuse Ratings - Samlexpower SEC-1260A Owner's Manual

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 30 A +/- 1 A for SEC-1260A, 40 A +/- 1 A for SEC-1280A
and 20 A +/-1 A for SEC-2440A. 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, Time Delay (Size 5mm x 20 mm, ceramic tube). Current ratings are as follows:
SEC-1260A:
•
For operation from 120 VAC input (pre-set) - 15 A
•
For operation from 230 VAC input (will require internal setting) - 8 A
SEC-1280A & SEC-2440A:
•
For operation from 120 VAC input (pre-set) - 20 A
•
For operation from 230 VAC input (will require internal setting) - 10 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-1260A
SEC-1280A
SEC-2440A
or
2 pieces in parallel, each rated at 32 V, 35 A
3 pieces in parallel, each rated at 32 V, 30 A
3 pieces in parallel, each rated at 32 V, 15 A
