2.1 GENERAL INFORMATION

SEC-1250UL (for 12V batteries) and SEC-2425UL (for 24V batteries) are high current, tem-
perature compensated 3 Stage Chargers that deliver Bulk Stage Currents of 50A and 25A
respectively ensuring a very fast, safe and complete charging of Lead Acid batteries. These
chargers can also be used as a Power Supply (Section 8.3) or as a DC UPS (Section 8.4).
2.2 FEATURES
• State-of-the-art Switch Mode Technology for high efficiency, light-weight and quiet
operation.
• User configurable AC input voltage – 120 VAC or 230 VAC, 50 / 60 Hz
• Automatic operation for all types of Lead Acid Batteries - Flooded, AGM or Gel Cell
• User selectable 2 or 3-Stage automatic charging algorithm with timed Absorption
Stage and temperature compensation ensures rapid, safe and full return of capacity
for stand-alone and loaded batteries.
• Ability to reduce maximum charging current to approximately 1/2 of the rated capac-
ity 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 depend-
ing upon the depth of discharge of the connected batteries.
• Voltmeter and Ammeter for monitoring
• 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 Model 900-RC with 10 Meters of wire for remote
ON/OFF control and indication of charging status.
• Conforms to UL Standard 1564 and certified to CSA STD. C22.2 No.107-2
• EMI compliant to FCC Part 15(B), Class B
2.3 MAXIMUM Ah CAPACITY OF BATTERY TO BE CHARGED
If the chargers are used to charge very high capacity batteries, they will be forced to sup-
ply their maximum rated charging current for longer time than the designed limit and
hence, the components will be overstressed and are likely to fail prematurely. To prevent
premature failure, the maximum Ah capacities of the batteries must be limited as follows:
- SEC-1250UL: 500 Ah
- SEC-2425UL: 300 Ah
