IMPORTANT SAFETY PRECAUTIONS
Hazardous conditions may result if the charger is not installed or operated correctly.
Please read the following instructions to prevent personal injury or damage to the
charger.
BATTERY RELATED
•To reduce the risk of battery explosion, follow these instructions and those marked
on the battery.
•Never smoke or allow an open spark or ame in the vicinity of the battery or the
engine.
•Charge only Lead Acid type of batteries (Flooded / Absorbed Glass Mat (AGM) /
Gel Cell). Do not charge other type of batteries like Nickel Cadmium (NiCad),
Nickel-Metal Hydride (Ni-MH), Dry-Cell etc. Other types of batteries
might burst causing personal injury.
• Never charge a frozen battery.
•Working in the vicinity of Lead Acid batteries is dangerous. Batteries generate
explosive gases during normal operation. Take necessary safety precautions when
installing the charger near a battery or in a battery compartment (Follow safety
instructions given by the battery manufacturer).
•Never place the charger directly above or below the battery being charged; gases or
uids from the battery will corrode and damage the charger. Locate the charger as
far away from the battery as DC cables permit. Do not install in the same com-
partment as batteries.
CHARGER RELATED
•Do not operate the charger in a closed-in area or restrict ventilation in any way.
Install in a well ventilated, cool, dry place.
•The charger must not be operated in a damp or wet environment. When mounting
in a boat, make sure it is not subjected to bilge water splash.
•Do not block the ventilation openings / openings for the cooling fan. There should
be at least 6 inches clearance all around the unit.
•Installation and wiring must comply with the local and the national electrical
codes. It is recommended that installation and wiring may be done by a certied
electrician.
•Wrong installation on a boat may lead to corrosion of the boat. It is recommended
that installation on the boat must be carried out by a boat electrician.
•Disconnect the AC input power to the charger before connecting / disconnecting
the batteries or other DC loads or when working on the charger.
•Disconnect the AC input power before changing the setting of the Dip Switches.
•The chassis of the charger is connected to the earth ground pin of the power cord
plug. Ensure that the earth ground pin of AC receptacle feeding the charger is
connected to earth ground.
•Do not use an adapter. If a grounding type of receptacle is not available, do not use
this charger until the proper outlet is installed by a qualied electrician.
• Do not operate the charger if the power cord is damaged.

DESCRIPTION
SEC-1245E/SEC-1260E/SEC-1280E (for 12 V batteries) SEC-2425E and SEC-2440E
(for 24 V batteries) are high current, 3 Stage Chargers that deliver 45 A 60 A, 80 A, 25 A
and 40 A respectively for almost 75% to 80% of the charging cycle ensuring a very fast,
safe and complete charging of lead acid batteries. The nomenclature “ I Uo U” is a DIN
nomenclature and signies the 3 charging stages – I for constant current Bulk Charge
Stage 1, Uo for constant over voltage Absorption / Boost Stage 2 and U for constant
voltage Float / Maintenance Stage 3 ( under DIN specication, voltage is designated
“U” and current is designated “I”. The subscript “o” in “Uo” signies over voltage).
FEATURES
•Fully automatic – “Connect and Forget” operation.
•Suitable for ooded , AGM or Gel Cell type of lead acid batteries.
•State-of-the-art switched mode technology is used for high efciency, lightweight
and quiet operation.
•User selectable 2 or 3-Stage automatic charging algorithm with timed Boost /
•Absorption Stage and temperature compensation ensures rapid, safe and full
return of capacity.
•Ability to reduce maximum charging current to approximately 1/2 of the rated
capacity during “Half Power Mode”. This allows safe charging of lower capacity
batteries.
•Includes a Battery Temperature Sensor allowing temperature compensated charging,
if required.
•2 banks of batteries can be charged simultaneously without the use of an external
battery isolator. The charging current will be shared between the two banks
depending upon the depth of discharge of the connected batteries.
•3 colour LED indicates charging status.
•Fan cooled - fan on/off based on output current.
•Protections against short circuit, over current, reverse battery connection and
over-temperature.
•Can be used as a power supply or as a DC UPS ( Uninterruptible Power Supply)
•when used in conjunction with a battery.
•Optional Remote LED Panel with 10 Metres of wire for remote on / off control and
indication of charging status.
