Unit Settings: 

 

How to Set the Type (Design, Technology) of Main Battery "I": 

Eight (8) charging programs

 for the different battery types are stored in the unit.

 

They can be selected by means of the 

3 micro slide switches 

at the unit front. See connection 

plan:  

The 

control levers

 of the slide switches are shown in 

white

If not being specified divergently by the battery manufacturer, the suitable charging program for the 
supply battery Board 

I

 can be determined by means of the following description and the technical data 

(voltage rates U1 and U2). 

The possible parallel/floating operation with consumer loads 12 V being connected to the 
battery is also automatically considered by all charging programs. 

TS 

= Temperature Sensor 825 (effect with/without connection of the temperature sensor) 

 

Charging Programs 

1) – 4) 

for 

Lead 

Batteries (Acid, Gel, AGM):

 

Four (4) charging programs, charging voltage rates and temperature equalization for batteries in lead 
technology: 

 

 

 

 

U1=14.40 V 

U2=13.50 V 

U3=13.20 V 

 

  2-5 h 

  24 h            Continuous 

 

Regeneration: 2 x week 1 h 

Universal charging program for 

 

acid-lead-acid batteries acc. to DIN 57 510/ 

 

VDE 0510 for charging and trickle charging of 

 

supply (board) batteries. 

Ensures short charging 

times, high charging factor and acid mixing for open 
standard batteries and closed, SLA, low-
maintenance, maintenance-free "non-solid 
electrolyte", "lead-acid", drive, lighting, solar and heavy-duty batteries. Also suitable for recently developed batteries (low-
antimonous, with silver-alloy, calcium or similar) and batteries with low (L) and very low (VL) water consumption. 
Adapted to closed, gas-tight 

AGM 

(absorbed glass mat) / lead-fleece batteries 

VRLA 

with indication of the charging voltage 

"

14.4 V

". 

 

 

 

 

U1=14.20 V 

U2=13.40 V 

U3=13.10 V 

 

  2.5-6 h 

  24 h           Continuous 

 

Regeneration: 2 x week 1 h 

Characteristic line similar to dynamo/generator for 

(mobile) application

 (acid accumulation) with 

particularly low maintenance (battery gassing). 
Charging and trickle charging of 

starter batteries in 

intervention vehicles,

 in conformity with the 

Standard Committee Fire Protection (

FNFW

). 

Permanent readiness for use, even with additionally 
connected consumers. For conventional, standard starter batteries, starter batteries being "absolutely maintenance-free", 
"maintenance-free according to EN", "maintenance-free according to DIN", "maintenance-free", "low-maintenance".
