1. General
Fully electronic mains/charger unit.
- 12 V DC and 24 V DC outputs
- Voltage-stabilized with current limitation
- Redundancy standby operation with accum. monitoring
- Deep-discharging protection
- Charging circuit monitoring
- Recognition of defective batteries
- Accumulator capacity up to max. 80 Ah
Recommended housing for installing: Type ZG 3.1 or larger
When selecting the size of housing, pay attention to the
space required for the accumulators.

Attention
Safety instructions
When performing installation work of any kind, the unit must
be de-energized. Before opening the housing, wait until the
electrolytic capacitors are discharged (approx. 3 minutes).
Never operate the unit without the housing.
When installing the power unit in a control panel housing or
equivalent, ensure that the supplied
insulating foil has been
inserted between the housing base and the underside of
the PCB
and that the supplied distance bold is screwed tight
to the housing base.
The non-fused earth conductor from the electric power circuit
must be connected in the immediate vicinity of the connection
terminals of the supply voltage.
The power supply line must be fixed when connecting so that
the
clearance (4 mm)
and
creep paths (5 mm)
between the
electronic modules and/or their periphery and the power
supply line are not shorter than stipulated.
If the neutral line cannot be clearly identified, a second pro-
tection must be available in the electric power circuit so that
2-pole separation from the electric circuit is possible.
The connection terminals must be protected against touching
inadvertantly by using the supplied cover.
4. Functional description
Two independent control circuits are installed on the mother-
board.
- First control circuit:
Supplies the control panel and the external users.
A) - Output
control panel
supply (ST100)
- Additional: outputs ST101 and BU100
The outputs are protected by the internal current control.
When installing in accordance with VdS, make sure
that there is a minimum load of 500 mA as supply
current.
B) - 2 outputs for
external user
The outputs are protected with fuses (1.6 AT per output).
When installing in accordance with VdS, make sure
that there is a minimum load of 100 mA per output as
external load current.
- Second control circuit:
Serves as a charger for the accumulators. The charging
current is limited to 3.5 A.
The accumulator charging voltage is monitored and ad-
justed according to the temperature with the aid of an NTC
resistor.
The charge t
erminating voltage
has been correctly set be-
fore leaving the factory (for Sonnenschein A500 series).
If it requires resetting, proceed according to Chapter 5 "Set
charge terminating voltage".
The supply voltage for the control panel and external users do-
es not require adjusting as it is monitored and adjusted by the
accumulated charging voltage so that in case of a mains failure,
large voltage jumps are avoided.

2. VdS guidelines for power supply
The power supply must be connected to the mains with a
separate fuse.
If the electrical installation has an earth-leakage circuit breaker
(Fl switch), the energy supply must have its own earth-leakage
circuit breaker. The fuse and Fl switch should, if possible, be
within the security zone.
If the energy supply is not part of the control panel, it must be
installed in the immediate vicinity (without a space between) so
that an attack on the connection line is impossible without
causing mechanical damage to the housing.
The control panel and power supply should, if possible, be
screwed together.
Users not belonging to the system should not be connected to
the mains voltage.
The accumulators used in the power supply must be
approved. For parallel switching, only accumulators of the
same age and from the same production series are allowed
to be used.
The accumulators must be fixed on the housing base using
Dual lock fasteners
(Item no. 055280).
