FEATURES
DESCRIPTION
● Electronic systems supply
● used as bells and doorchimes trans-
formers,
● short circuits and overloads resi-
stant,
● inner thermal protection,
● threemodular casing,
● TH-35 DIN rail or surface mounting.
Transformers are used to supply
electronic systems where it is required
to lower voltage value to the appropriate
level. The universal casing enables mo-
unting on the TH-35 DIN rail or on the
surface. Available versions of secondary
voltage: 8 V AC, 12 V AC, 24 V AC and
3 V AC, 5 V AC, 8 V AC.
The device is designed
for single-phase installa-
tion and must be installed
in accordance with stan-
dards valid in a particular
country. The device should
be connected according to
the details included in this operating ma-
nual. Installation, connection and con-
trol should be carried out by a qualied
electrician staff, who act in accordance
with the service manual and the device
functions. Disassembling of the device is
equal with a loss of guarantee and can
cause electric shock. Before installation
make sure the connection cables are
not under voltage. The cruciform head
screwdriver 3,5 mm should be used to
instal the device. Improper transport,
storage, and use of the device inuence
its wrong functioning.
It is not advisable to instal the device in
the following cases: if any device part is
missing or the device is damaged or de-
formed. In case of improper functioning
of the device contact the producer.
