3B SCIENTIFIC PHYSICS 1003310 Instruction Sheet
Disconnect the equipment from the mains
before replacing a fuse.
Never short the fuse or the fuse holder.
Never cover the air vents in the housing. This is
necessary in order to ensure sufficient circula-
tion of air required for cooling the internal
components of the equipment.
The equipment may only be opened/repaired
by qualified and trained personnel.
2. Description
The 5 kV high voltage power supply is a universally
usable non-earthed high voltage source for operat-
ing electron tubes.
It provides a continuously variable stabilized high
voltage with passive current limitation, in a hous-
ing that is safe to handle. It also incorporates a
transformer, insulated against high voltage, to
supply the cathode heater voltage for an electron
tube. A temperature-controlled fan protects the
equipment from overheating.
The 1003309 high voltage power supply is for op-
eration with a mains voltage of 115 V (±10%), and
the 1003310 unit is for operation with a mains
voltage of 230 V (±10%).

4. Operation
4.1 General information
Before switching on the power supply, set the
high voltage regulator to zero (turn fully to the
left).
Connect the power supply to the experimental
setup.
Do not switch the power supply on until the
experiment has been fully assembled.
Changes to the experimental setup must only
be made with the power supply switched off.
Set the high voltage regulator to give the re-
quired voltage.
Before switching off the power supply, set the
high voltage regulator to zero again (turn fully
to the left).
4.2 Changing the fuse
Turn off the power switch and unplug the
mains plug.
Unscrew the fuse holder on the rear side of the
housing with a screwdriver.
Replace the fuse and reinsert the holder in its
socket.
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 equipment
itself, never throw it away in normal domestic
waste. Local regulations for the disposal of
electrical equipment will apply.
