RECTIFIER FUNCTION

The IUOU charger can be used as a 12V/24V mains unit

provided that the maximum current consumption of the

consumers does not exceed the rated current of the charger. It

is recommended to have battery connected (Fig. 2) in any

case. The consumers should be connected directly to the battery.

This applies in particular to consumers with high peak

currents (e.g. high start-up current in the case of compressors).

In parallel operation (consumers and battery), the maximum

consumer current should be less than the rated current of the

charger because otherwise the battery will discharge.

Maximum current consumption of consumers when used as a

mains unit (Fig 1).

INFORMATION ON CAUTION & WARNING SIGNS

Warning! Safety warning: Failure to observe this warning may result in injury to

persons and damage to equipment.

Caution! Safety warning: Failure to observe this warning may result in damage to

equipment and improper functioning of the IUOU charger.

GENERAL SAFETY AND INSTALLATION INFORMATION

Warning! The following fundamental safety measures must

be observed when using electrical equipment to avoid the

danger of: electric shocks

fire

injury

ABOUT THE UNIT ITSELF

The IUOU charger may only be used for the purpose specified by

the manufacturer!

When working on the IUOU charger, always disconnect from the mains!

Do not operate the IUOU charger if the housing or cables are

damaged!

The IUOU charger must be positioned and fixed in such a way

that it cannot fall over or fall down!

The IUOU charger may only be connected to earthed sockets!

Ensure good ventilation.

The IUOU charger must be kept in a safe place out of the reach of

children!

Warning! Protect and always operate the 115V connection

of the IUOU charger via a GFCI (Ground Fault Circuit

Interrupter) of 30mA fault current.

The IUOU charger may not be operated in damp or wet environment!

Servicing and repair may only be carried out by skilled personnel

being familiar with the risks involved and the relevant regulations!

CAUTION FOR INSTALLATION ON BOATS!

Wrong installation of electrical units on a boat may

lead to corrosion of the boat. Therefore, please let a

(boat) electrician carry out the installation of the charger.

SEC-1245A = max. 45 Ampere

SEC-2425A = max. 25 Ampere

CHARGING

The 3 phase IUOU charge characteristic guarantees

rapid, complete and at the same time gentle charging

of the battery.

Stage 1: THE I-PHASE. The battery is charged at

constant current (45A for SEC-1245A or 25A for SEC-

2425A) until it approaches the float voltage. The

control LED glows red. The output voltage is

determined by the battery voltage.

Stage 2: UO-PHASE. On reaching 80% of the max.

rated current, the charging takes place at a constant

Boost Voltage of 14.4V (SEC-1445A) or 28.8V (SEC-

2425A). The charger remains in this stage until the

current reduces to 10% of the max. rated current or 2

hours, whichever is earlier. The control LED glows yellow.

Stage 3: U-PHASE. After the UO-phase, the charging

voltage switches over to floating voltage (13.8V for

SEC-1245A and 27.6 for SEC-2425A). In this phase, the

battery is practically at rest and only takes the current

necessary for maintaining the capacity. The LED light

is green.

If a load is connected to the battery in this phase, it is

possible that the charger switches back to the UO-phase

until the 2 hour time limit is reached. Otherwise it

remains in this U-phase.

CAUTION!

Batteries with a cell closure may not be charged,

as there is the danger of explosion by occurrence

of electrolytic gas.

Ni-Cd batteries and non-rechargeable batteries

may not be charged. The casing of these batteries

can burst by explosion.
