1. Safety instructions
The high voltage power supply E conforms to all
safety regulations for electrical measuring, control,
monitoring and laboratory equipment, as specified
under DIN EN 61010, Section 1, and the equipment
has been designed to meet protection class I. It is
intended for operation in a dry environment, suitable
for the operation of electrical equipment and sys-
tems.
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 power supply unit must be su-
pervised by qualified personnel.
•
Before using the power supply unit for the
first time, confirm that the specifications
printed on the rear side of the housing are
compatible with the local mains voltage.
•
Before using the power supply unit for the
first time, check the housing and the mains
lead for any damage. In the event of any
malfunction/operational defect or visible
damage, switch off the unit immediately and
secure it against unintended use.
•
The instrument may only be connected to
the mains via a socket that has an earth
connection.
•
Before making any connections, check the
experiment leads for damaged insulation
and exposed wires.
•
Replace a faulty fuse only with one mat-
ching the specifications stated at the rear of
the housing.
•
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 suffi-
cient circulation of air required for cooling
the internal components of the equipment.
•
The equipment
ned/repaired by qualified and trained per-
sonnel.
may only be ope-
2. Description
The high voltage power supply E is a universally
usable non-earthed high voltage source for op-
erating electron tubes.
It provides a continuously variable stabilized
high voltage with passive current limitation, in a
housing that is safe to handle. It also incorpo-
rates a transformer, insulated against high volt-
age, to supply the cathode heater voltage for an
electron tube. A temperature-controlled fan pro-
tects the equipment from overheating.
The 1017725 high voltage power supply is for
operation with a mains voltage of 115 V (±10%),
and the 1013412 unit is for operation with a
mains voltage of 230 V (±10%).

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 experimen-
tal setup.
•
Do not switch the power supply on until the
experiment has been fully assembled.
