switch off the unit immediately and secure it
from unintentional use.
•
Connect the equipment only to sockets with
an earthed neutral.
•
Before making any connections, check the
experiment leads for damaged insulation
and exposed wires.
•
Replace any blown fuses only with new
ones that match the specifications stated on
the rear of the housing.
•
Never short the fuse or the fuse holder.
•
Never cover the air vents and heat sink at
the rear of the housing. These are neces-
sary in order to ensure sufficient circulation
of air required for cooling the components
inside the equipment.
•
The equipment may only be opened/repaired
by qualified and trained personnel.
•
Never switch on the power supply unit im-
mediately after it has been brought from a
cool environment into a warm environment.
The condensed water formed on account of
a sudden change of temperature can, under
unfavourable conditions, be damaging for
the equipment. Do not switch on the equip-
ment without first allowing it to attain ambi-
ent temperature.
•
Never operate power supply units unat-
tended or without supervision.
2. Description
The 1.5-15 V DC power supply unit provides a
continuous DC voltage which can be regulated
between 1.5 V and 15 V at a current of 1.5 A.
The power supply unit is equipped with an elec-
tronic current limiting system and a thermal pro-
tection mechanism. The DC power supply unit
has a built-in mains fuse which is accessible
only after the equipment has been opened (see
"Safety instructions").
If operating for a long period at maximum cur-
rent and low output voltage or when short-
circuited, the equipment's heat sink becomes
very hot. When the heat sink has exceeded a
critical temperature, the equipment shuts off
automatically. After a cooling period of approx.
2-3 minutes, the equipment simply has to be
switched off and on again, after which it is once
again operational.
The power supply 1003559 is for operation with
a mains voltage of 115 V (±10%), and the unit
1003560 is for operation with a mains voltage of
230 V (±10%).

4. Operation
Obtaining a DC voltage
•
Connect the unit to the mains supply. Turn
the voltage control knob fully to the left.
•
Connect the load to the output sockets.
•
Press the mains switch; the indicator LED
lights up.
•
Set the required voltage using the
knob for output voltage
5. Care and maintenance
•
Before cleaning the equipment, disconnect it
from its power supply.
•
Use a soft, damp cloth to clean it.
6. Disposal
•
The packaging should be disposed of at
local recycling points.
•
Should you need to dispose of the equip-
ment itself, never throw it away in normal
domestic waste. Local regulations for the
disposal of electrical equipment will apply.
