power supply unit
type 2225.4
The intended application of the power supply unit covers:
- link and operation of low-voltage consumers with an operating voltage between 0 and 35 VDC. The power input of
the consumer may not exceed 5 A.
Note! Absolutely read!
- Read this guidance exactly. With damage, which is caused by neglect of the guidance, the warranty claim goes
out. For damages we do not take over adhesion.
1. introduction
this power supply unit is universally applicable with its infinitely variable adjustment possibilities of voltage and
current for school, occupation, hobby etc.. An electronic current limiting protects the power supply unit against
overloading. Output voltage and - current are electronically stabilized and infinitely variable adjustable. Thus the
electronic restraint current can as adjustable Current limiting to be used, in order to protect consumers against a too
high power input. In the case of an overloading the output voltage is then lowered accordingly (in the case of short-
circuit on close 0V). With removal of the overload the output voltage adjusted before resets itself automatically. The
respective operating point - voltage - (u) - or restraint current (i) - is displayed by one red LED each. The adjusted
values are readable over 2 LCD displays or analog displays each. The voltage or current adjustment is made by one
double button each (rough- fine). Additionally a change .

4. Line-up
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
gleichspannungsquelle against thermal overloading one protects.
Pay attention therefore absolutely to a sufficient ventilation of the power supply unit Verdecken 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.
