power supply unit
0 ... 32 V / 0 ... 3,0 A
type 2223.2
The intended application of the power supply unit covers:
- -link and operation of low voltage consumers with an operating voltage between 0 and 32 VDC. The power
input of the consumer may not exceed 3,0 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 .-
2. Safety notes
2,1 the power supply unit is in safety class system I as well as in accordance with VDE 0411 and VDE 0805
(EN60950) structured. The supply transformer is structured and with 3,75 kVeff is primary secondarily
checked according to DIN VDE 0551 as safety insulating transformer. It is radio-screened in accordance with
VDE 0875T11 curve B. Es is equipped with a VDE checked main with protective grounding and may
therefore only to 230 Wechselspannungsnetzen with protective grounding be operated or attached-V- .
2,2 it is to be made certain that protective grounding (yellow/green) is interrupted neither in the main nor in the
device or in the network, since with interrupted protective grounding mortal danger exists. It is to be made
certain further that the isolation is damaged nor destroyed neither.
2,3 power supply units do not belong into child hands!

the commercial Professional association for electrical system and resources.

2,6 when opening covers or removing from sections, except if this, can live sections be opened. Also interface can
be live. Before an alignment, maintenance, a repair or an exchange of sections the device must be separate
from all voltage supplies, if opening of the device is necessary. If thereafter an alignment, maintenance or a
repair at the opened device under voltage are inevitable, may take place only by means of a specialist, who is
familiar with the associated dangers or the relevant regulations for it.
2,7 condensers in the device can be still loaded, even if the device were separated from all voltage supplies.
2,8 it is to be guaranteed that only protections of the indicated type and the indicated call stromstraerke are used
as back up. The use of repaired protections or bridging the fuse holder is illegal. The device is overload- -proof
and short otected. When burning the input protection through a serious error is therefore present, - -circuit pr

2,9 switching it your power supply unit never equivalent if it is brought by a cold into a warm space. The
condensation developing thereby can destroy your device under unfavorable circumstances. Let the device
unein switched to room temperature come. carrying of metallic or conductive decoration is forbidden to

2,11 power supply units are not certified for application at humans or animals.
2,12 during the series connection of the outputs one or several power supply units is produced lethal voltages (>35
VDC).
2,13 louvers of power supply units may not be taken off! The devices are on hard to place with difficulty
inflammable documents so that air can occur the devices unhindered. The cooling of the devices takes place
predominantly via convection.
2,14 power supply units and the attached consumers may not be operated unsupervised. Measures are to be
taken to the protection and the protection of the attached consumers in relation to effects of the power supply
units (e.g. overvoltages, failure of the power supply unit) and the effects and dangers outgoing from the
consumers themselves (e.g. illegally high power input). Note! Sensitive consumers must be protected
additionally by external measures against destruction!
2,15 in the event of an error can deliver power supply units voltages over 50 V DC voltage, from which dangers
proceed, also then if the indicated output voltages of the devices lower is situated.
2,16 with work under voltage for it expressly certified tools may be only used.
2,17 the outputs of the power supply units (exit hub/clamps) and to it attached lines must be protected against
direct contact. In addition the used lines must sufficient isolation or tension strain possess and the contact
point voltages be contact- -proof (safety sockets).
2,18 shifting metallically bright lines and contacts is to be avoided. All these places are by suitable to take and to
protect thus against direct contact with difficulty inflammable insulants or other measures off. Also the
electrically leading sections of the attached consumers are to be protected by appropriate measures against
direct contact.
2,19 if to assume it is that a safe operation is no longer possible, then is the device out of operation to set and
against unintentional operation protect. It is to be assumed that a safe operation is no longer possible, if - the

a) link connecting it the GND contact power supply plugs of the power supply unit with a connector 230V/50Hz -
/60Hz. paying attention it when connecting a consumer absolutely to the fact that this is attached in the not
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 can damage again the female connectors or the attached
lines and/or their clamps. Switch the power supply unit on over the power switch.
Note! With longer operation with max. current consumption (ä) or in the case of short circuit the radiator box in the -
power supply unit becomes very warm. Caution! Burn danger! Absolutely pay attention therefore to a sufficient
ventilation of the power supply unit and never cover them the ventilation slots on the device waiters - or device
lower surface, in order to avoid possible damage.
b) Voltage adjustment
Turn first the rough reset 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.
c) Adjustment of the current

display for output current displays, depending upon adjustment of the rough or fine reset 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.
Note! Absolutely consider the safety notes with paragraph 2 of this guidance.
