1. Safety instructions
The transformer 12 V, 60 VA conforms to all
safety regulations for electrical measuring, control,
monitoring and laboratory equipment, as specified
under DIN EN 61010, Section 1, and the equip-
ment has been designed to meet protection
class II. It is intended for operation in a dry envi-
ronment, suitable for the operation of electrical
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. visi-
ble damage), the equipment should be switched
off immediately and secured against any unin-
tended use.
In schools and other educational institutions, the
operation of the transformer must be supervised
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 transformer, 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.
2. Description
The transformer supplies an AC voltage of 12 V
for student experiments. It is especially suitable
as a power source for optical lamps.
It is moulded in an impact-resistant plastic block,
is protected against short-circuiting, and is pro-
vided with two safety plugs.
The transformer is available in 2 versions for
differing mains voltages. The transformer with the
order number 1000593 is for mains supplies of
230 V (±10%) while the one with order no.
1006780 is for 115 V (±10%) systems.
