EN 

• Automatic compensation of voltage loss caused by the charging cable length (house battery)

• AUX connection usable for controller output, split-charge relay, or electrical devices (only PSB12-40,

PSB12-80, PSB24-40, PSB24-60)

The charger has the following protective mechanisms:

• High voltage protection

Battery charging function

A main charging cycle of the house battery is initiated in the following situations:

• After a standstill of the alternator

• After falling below the reset voltage

ﬁg. on page2

In all charging phases, almost the entire possible charger current is available for the additional supply of DC loads

without discharging the battery.

The charging characteristics for fully automated continuous operation without monitoring are referred to as IU0U

characteristics.

1, 2: Analysis phase (Recondition and pulse)

The battery is deeply discharged (> 10 %). The battery charge is analyzed with increasing charging current.

EN 

3, 4: I phase (Constant current phase – Bulk)

At the beginning of the charging process, the empty battery is constantly charged with half of the the maximum

charging current (50 %). The charging current increases to 100 % after 1 min. Deeply discharged lead batteries are

charged with reduced charging current until the battery voltage exceeds 8 V. The duration of the I phase depends

on the state of the battery, the load from the consumers and the state of charge. For safety reasons the I phase is ter-

minated after a maximum of 15 h (in case of battery cell defects or similar).

5: U1 phase (Constant voltage phase – Absorption)

The U1 phase starts when the battery is fully loaded. The charging current is reduced. During the U1 phase, the bat-

tery voltage is kept constant at a high level. The duration of the U1 phase depends on the battery type and the depth

of discharge.

6: Desulfation phase

A constant current will be delivered, allowing the battery voltage to rise independently to the maximum value. The

desulfation phase is not used for LiFePO4 batteries.

7: U2 phase (Trickle charging – Float)

The U2 phase serves to maintain the battery capacity (100 %). The U2 phase runs at lowered charging voltage and

variable current. If DC loads are connected, they are powered by the device. Only if the power required exceeds the

capacity of the device, this surplus power is provided by the battery. The battery then is discharged until the device

re-enters the I phase and charges the battery.The U2 phase is limited to between 24 and 48 h depending on the bat-

tery type.

8 Installation

Before installation
