This power supply has been designed specifically
for use in teaching physics, chemistry and other
science subjects. The power supply can provide
both direct current (DC) and alternating current (AC).
The power supply can provide both types of electrical power at the same time, and they can be adjusted independently of one another. Separate displays
are provided for DC and AC output.
Safety
The power supply is of the switched mode type, and
it adheres to the EN-61558-1 standard. The connec tion jacks are safety-type 4 mm banana plug con nec tors and are well-suited for use with students.
The connectors will also accept leads with ordinary
bana na plugs. The apparatus is CE marked and
approved.
A power cord with ground is provided with the apparatus. The apparatus must be connected to a
power outlet with ground.
Under extreme conditions, which will rarely occur
under normal use (high temperature combined with
high loading for a long period of time), the power
supply will automatically shut down when a given
internal temperature is reached. The power supply
will turn itself on again, when it has cooled off.
Important !
Never connect two power supply outlets in parallel. This applies whether the outlets belong to the
same apparatus or to separate units.
Operation
The power supply is connected to the power outlet
230 VAC, 50 Hz (115 V 50/60 Hz) using the power
cord which is provided.
The apparatus must be connected to a power outlet
with ground.
The control panel is divided into two sections:
The DC-controls are to the left, the AC-controls are
to the right. Each section operates independently of
the other.
The numbered items on the control panel (see illustration) correspond to the following functions:

1) On/off switch with lamp
2) Connection jacks for AC
3) Connection jacks for DC
4) Regulating knob for AC
5) Regulating knob for the DC current limiter.
If a current limit is to be set, proceed as follows:
Adjust the voltage adjustment knob (6) to the
desired voltage. Short circuit the DC output connectors with a test lead. Use the current adjustment knob (5) to adjust the maximum current
desired. Remove the short circuit again.
The current is now prevented from exceeding this
value, regardless of the position of the voltage
regulating knob (6).
The maximum current which can be supplied is
shown on the following graph:
06) Regulating knob for DC voltage
07) Display showing the DC output voltage
08) LED (light emitting diode) indicator showing
whether the maximum current limit setting has
been reached. When the maximum current is
being drawn (cf. adjustment knob (5)), then the
LED will light up.
09) Display showing the DC output current
10) Display showing the AC output voltage
11) LED indicating whether or not the maximum
value of the current has been reached
(LED lights up).
12) Display showing the AC output current
Maintenance:
No special maintenance of the power supply is
necessary.
Service:
The power supply should only be serviced by
qualified personnel. During the guarantee period,
only personnel approved by Frederiksen A/S may
perform service repairs.
