Description
These chargers are used to charge Lead
Acid Batteries (Flooded, AGM or Gel Cell).
SEC-1215UL (Maximum charging current
15A) and SEC-1230UL (Maximum charg-
ing current 30A) are used to charge 12 V
batteries. SEC-2415UL (Maximum charging
current 15A) is used to charge 24 V batter-
ies. 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 10 for instructions).
Features
• State of the art switched mode technol-
ogy 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 10 for instructions).
• User selectable 2 or 3 stage charging
algorithm ensures rapid and safe charg-
ing of all types of lead acid batteries
- Flooded, AGM, Gel Cell or batteries
with external load. (Through externally
accessible DIP Switch - see pages 11 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-1230UL, SEC-2415UL)
• Protections against short circuit, over
current, reverse battery connection and
over temperature (over temperature for
SEC-1230UL and SEC-2415UL)
• 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-1215UL is cooled by convection and
does not have any thermal overload
shut down.
SeC-1230UL and SeC-2415UL are cooled by
convection and in addition, have a tem-
perature controlled fan for forced air cool-
ing. Two temperature sensors mounted on
the power transformer control the switch-
ing 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°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 sen-
sor will shut down the unit if the power
transformer reaches 100°C. The red LED
will switch off. The unit will automatically
recover on removal of thermal overload
condition.
