• Yellow  LED  “Uo  Phase”  is  lighted  –  Indicates  that  the  charger  is  in  Stage  2  –

Constant Overcharge Voltage, Timed Absorption / Boost Charge Stage (“Uo” Phase)

and is delivering between 36 A to 4.5 A (SEC-1245E),48 A to 6 A (SEC-1260E), 64 A

to 8 A (SEC-1280E), 20 A to 2.5 A (SEC-2425E) or between 32 A to  4 A  (SEC2440E)

• Green LED “U Phase” is lighted – Indicates that the charger is in Stage 3 - Constant

Voltage, Float or Maintenance Charge Mode (“U”Phase). The charger is delivering

<4,5 A (SEC-1245E) < 6A (SEC-1260E), < 8 A (SEC-1280E)< 2.5 A (SEC-2425E)

or < 4 A (SEC-2440E). The battery is fully charged.

OPERATION

SWITCHING ON / OFF

The charger is switched on /off with the illuminated AC input power on / off switch (9) 

located on the rear panel of the unit. The switch is illuminated Red when switched on.

INDICATION OF NORMAL OPERATION AND CHARGING STATUS

When the charger is switched on without any load, the Charging Indicator LED (4) on the

front panel turns Red, Orange and then Green. The fan (11) will come on momentarily and

switch off. If a Remote Panel is connected, its Green LED “Power” will light and the other 

3 LEDs  will light  in sequence - “I” Phase (Red),“Uo” Phase (Yellow) and then 

“U” Phase (Green).

If a battery or load is connected, the color of the Charging Indicator (4) on the front panel 

will indicate the charging status as follows: 

• Charging Indicator LED (4) on the front panel is Red

  – Indicates that charger is in

Stage 1 - Constant Current, Bulk Charge Mode (“I” Phase) and is delivering current

as follows:

SEC-1245E:

45 A to 36 A when in Normal Mode

22.5 A +/- 1A to 18 A when in Half Power Mode

SEC-1260E:

60 A to 48 A when in Normal Mode

30 A +/- 1A to 24 A when in Half Power Mode

SEC-1280E:

80 A to 64 A when in Normal Mode

40 A +/- 1A to 32 A when in Half Power Mode

SEC-2425E:

25 A to 20 A when in Normal Mode

12.5 A +/- 1A to 10 A when in Half Power Mode

SEC-2440E:

40 A to 32 A when in Normal Mode

20 A +/- 1A to 16 A when in Half Power Mode

• Charging Indicator LED (4) on the front panel is Orange

 – Indicates that the charger

is in Stage 2 – Constant Overcharge Voltage,  Timed Absorption / Boost Charge Stage

( “Uo” Phase) and is delivering the following current:

SEC-1245E

>than 9,5A +/- 1A and < 36 A (when moving from Float Phase “U” to 

(Normal Mode)

Boost Phase “Uo”) or < 36 A and > 4.5 A +/- 0.5A

(When moving from Boost Phase “Uo” to Float Phase “U”)
