Samlexpower SEC - 1215A Owner's manual - page 4
DESCRIPTION
These chargers are used to charge Lead Acid Batteries (Flooded, AGM or Gel Cell). SEC-1215A
(Maximum charging current 15A) and SEC-1230A (Maximum charging current 30A) are used to
charge 12 V batteries. SEC-2415A (Maximum charging current 15A) is used to charge 24 V
batteries. These chargers can be powered from AC power source of either 120 V, 60 Hz (Pre-set) or
230 V, 50 Hz (By changing jumper position inside the unit - See page 7 for instructions).
FEATURES
State of the art switched mode technology is used for very high efficiency, lightweight
and quiet operation.
User selectable AC input voltage - 120 V , 60 Hz ( Pre-set) or 230 V , 50 Hz ( By
changing jumper position inside the unit. See page 7 for instructions ).
User selectable 2 or 3 stage charging algorithm ensures rapid and safe charging of all
types of lead acid batteries - Flooded, AGM, Gel Cell or batteries with external load .
( Through externally accessible Dip Switch – see pages 7 & 8 for instructions )
Fully automatic “Connect and Forget” operation
3 banks of batteries can be charged simultaneously without use of an external battery
isolator
Monitoring through ON status LED and Ammeter
Temperature controlled cooling fan (SEC-1230A, SEC-2415A)
Protections against short circuit, over current, reverse battery connection and over
temperature
(over temperature for SEC-1230A and SEC-2415A)
Can be used as a power supply or as a DC UPS ( Uninterruptible DC Power Supply )
when used with a battery ( Dip Switch set at “Battery with load”)
COOLING
SEC-1215A is cooled by convection and does not have any thermal overload shut down
SEC-1230A and SEC-2415A are cooled by convection and in addition, have a temperature
controlled fan for forced air cooling. Two temperature sensors mounted on the power transformer
control the switching of the fan and over temperature shut down. The fan will be switched on by
the first temperature sensor when the power transformer reaches 70 degrees C. HENCE, AT
LOWER LOADS, THE FAN MAY NOT CUT IN AND WILL BE OFF. THIS IS NORMAL.
In case the fan fails or if the cooling is not adequate, the second temperature sensor will shut down
the unit if the power transformer reaches 100 degrees C. The red LED will switch off. The unit will
automatically recover on removal of thermal overload condition
