1. Safety instructions
The transformer conforms to all safety regulations for
electrical measuring, control, monitoring and labora-
tory equipment, as specified under DIN EN 61010,
Section 1, and the equipment has been designed to
meet protection class II. It is intended for operation in
a dry environment, suitable for the operation of elec-
trical equipment and systems.
Safe operation of the equipment is guaranteed,
provided it is used correctly. However, there is no
guarantee of safety if the equipment is used in an
improper or careless manner.
If it may be assumed for any reason that non-
hazardous operation will not be possible (e.g. visible
damage), the equipment should be switched off im-
mediately and secured against any unintended use.
In schools and other educational institutions, the
operation of the power supply unit must be super-
vised by qualified personnel.
•
Before using the power supply unit for the first
time, confirm that the specifications printed on
the housing are compatible with the local
mains voltage.
•
Before using the power supply unit, check it for
any damage. In the event of any malfunc-
tion/operational defect or visible damage,
switch off the unit immediately and secure it
against unintended use.

1 Transformer for 115 V mains
voltage
2 Transformer for 230 V mains
voltage
2. Description
The transformer supplies an AC voltage of 12 V for
student experiments. It is especially suitable as a
power source for the optical lamp K (U8475400).
It is moulded in an impact-resistant plastic block, is
protected against short-circuiting, and is provided
with two safety sockets.
The transformer is available in 2 versions for differing
mains voltages. The transformer with the order num-
ber U8475470-230 is for mains supplies of 230 V
(±10%) while the one with order no. U8475470-115 is
for 115 V (±10%) systems.
