1 SAFETY PRECAUTIONS

Carefully read these operating instructions completely
before operating this instrument. This is necessary to
avoid damage to it, as well as for user-safety.

Check that your mains supply voltage corresponds to
that given on the type plate fixed to the instrument.

Install the instrument so that the on/off switch and the
mains connecting plug are easily accessible. Do not
cover the ventilation slits.

Take care that no liquids or objects enter in through the
ventilation slots.

Only use the instrument in dry rooms in which there is no
risk of explosion.

Do not operate if there are visible signs of damage to the
unit or the connection cord.

Only use the instrument for the purpose for which it is
intended.
2 PURPOSE AND CHARACTERISTICS
This robust and practical isolating transformer (Fig. 1) is par-
ticularly suitable as a power supply for student experiments.
The output voltages are in the low voltage extent of protec-
tion. The instrument supplies both an alternating voltage of
up to
14 V, which is selectable in seven equal steps of 2 V,
and a direct voltage that is obtained by bridge rectification.
The direct voltages are about 2
V lower than the alternating
voltages, because of the threshold voltage of the rectifier di-
ode. The voltages are also dependent on the load (see the
diagrams in Figs. 3 and 4).
3 FUNCTIONAL AND OPERATING ELEMENTS
The unit is accommodated in an impact resistant plastic
housing. A retractable carrying handle is recessed into the
unit and can be folded down so that the instrument slopes
down towards the back. Four rubber feet provide resistance
to slipping. The unit can be stacked onto other units of the
same design, because the rubber feet fit into cup-shaped re- Attention!
