a) The euro - connector of the power supply unit into
- a plug socket 230V/50Hz and you switch link putting you for earthing contact on the power supply unit over the
power switch.
- Note! With longer operation with max. current consumption (5,0A) or in the case of short-circuit the radiator
box in the power supply unit becomes very warm. An overloading of the power pack is displayed by the red LED "
temperature rise ". At the same time by lowering the original data of the longitudinal automatic controllers of the
regulator against thermal overloading one protects.
Pay attention therefore absolutely to a sufficient ventilation of the power supply unit covering it never the ventilation
slots at the device lower surface and at the rear wall the air outlet opening of forced cooling. Absolutely make sure
when connecting a consumer that this is not attached in the switched on status. A switched on consumer can lead with
the link to the output terminals of the power supply unit to a sparking at the connecting terminals, which again
b) Adjustable of the voltage
Turn first the adjusting knob for the current limiting a little to the right (in the clockwise direction), until the LED (= light
emitting diode) for current limiting goes out. In the same instant the LED for the voltage adjustment begins to light up.
Now you can adjust the desired output voltage. The LCD display displays the adjusted output voltage.
c) Adjustment of the current limiting closing it the output
terminals with switched off power supply unit briefly. Switch then the network on. The display for output current
displays,
depending upon adjustment of the adjusting knob for current limiting, a value. Stop the current limiting, i.e. the "
maximum stream ", with which the power supply unit is to limit. After adjustment they open the short-circuit with
switched off power supply unit, since otherwise an outline spark can develop. Series connection / parallel connection
around optimal base values to achieve and overloading avoid should become preset the sources with for instance the
same original data. Max. 2 sources in series may do geschalten to become.
Note! Absolutely consider the safety notes with paragraph 2 of this guidance.
