5.5 Mains cable
Do not modify or repair mains supply components including mains plugs,
mains cables, and power supplies. Do not use damaged components. Risk
of death by electric shock!
The mains outlet must be located near to the device and be easily accessible.
Never plug in or unplug the mains plug when your hands are wet.
Never pull the mains plug from the socket by pulling at the cable. Always pull it from the
mains socket using the intended grips.
Unplug the mains plug from the mains socket if you do not use the device for an extended
period of time.
Disconnect the mains plug from the mains socket in thunderstorms for reasons of safety.
Make sure that the mains cable is not squeezed, bent, damaged by sharp edges or put
under mechanical stress.
Avoid excessive thermal stress on the mains cable from extreme heat or cold.
Do not modify the mains cable. Otherwise the mains cable may be damaged. A damaged
mains cable can cause a deadly electric shock.
Do not touch the mains cable if it is damaged.
– First, power down the respective mains socket (e.g. via the respective circuit breaker)
and then carefully pull the mains plug from the mains socket.
– Never use the product if the mains cable is damaged.
A damaged mains cable may only be replaced by the manufacturer, a workshop commis-
sioned by the manufacturer or a similarly qualied person, so as to prevent any danger.
Ensure that cables are not pinched, kinked or damaged by sharp edges.
Always lay cables so that nobody can trip over or become entangled in them. This poses
a risk of injury.

8 Functional Description
The DC output of the power supply unit is electrically isolated and features protective separa-
tion from the mains voltage.
A controllable low voltage protection is provided at the output. The control buttons are digitally
controlled and when a button is pressed direct adjustment of the individual digits is made pos-
sible. A turn in a clockwise direction increases the adjustment value.
It is also possible to continuously adjust the current limit. A jumper at the output is not needed
for the adjustment of the current. A turn in a clockwise direction increases the adjustment value.
The momentary output voltage (V) and the output current amperage (A) is shown in the display
(1).
A secondary side DC connection is possible via two coloured 4mm safety sockets (4 and 5).
Two USB loads can be connected to the two high-power USB outputs AUX.1 and AUX.2, re-
gardless of the regulated laboratory power pack.
The power supply unit is cooled passively through convection. Therefore, ensure sufcient air
circulation and space on the side.
If the preset current limit is exceeded through overload or short-circuit, then
this is signalled via the “C.C.” display. It will electronically reduce the output
voltage to avoid damage to the power supply unit.
9 Operation
a) General information
To operate the power supply unit you need a mains lead containing a protective earth wire,
which is included. Use only this one or an identical mains cable. Connect the mains lead
to the IEC input (11) on the rear of the power supply unit and plug the mains plug into an
earthed mains socket.
The power supply unit is not a charger. To charge batteries, use suitable chargers with a
charging current cut-off.
Always turn the device off when it is not in use.
b) Setting the output voltage
Ensure that there are no loads connected to the mains power supply.
Switch on the mains power supply at the power switch (13). The display is illuminated.
Make sure that the “C.V.” indicator is on. If this is not the case and indicator “C.C.” is on,
turn the current adjustment control “CURRENT” (7) in a clockwise direction.
Turn the adjustment control “VOLTAGE” (6) to roughly the desired output voltage. Access
the ne adjustment menu by briey pressing on the control button (6). The rst decimal of
the voltage “V” starts ashing. The value of this decimal can be changed by turning the
control button.
Switch to the next decimal by pressing the button again briey. Make the adjustment until
you reach the desired voltage value.
Wait a few seconds for the laboratory power supply to return to the normal setting.
c) Setting the current limitation
Adjust the output voltage as described above.
Turn the adjustment control “CURRENT” (7) roughly to the desired current limit. Access the
ne adjustment menu by briey pressing on the control button (7). The rst decimal of the
current indicator “A” starts ashing. The value of this decimal can be changed by turning
the control button.
Switch to the next decimal by pressing the button again briey. Make the adjustment until
you reach the desired current value.
Wait a few seconds and the laboratory power pack returns to the normal setting. The cur-
rent indicator shows 0.000 A.
To check the setting for the current, briey press control button “Current” (7). The value of
the current limit is briey displayed.
If no current limit is needed, ensure that it is always set to the highest current value so that
operation of the power supply is not reduced.
d) Enabling/disabling outputs
Press the “OUTPUT” button (2) to enable the adjustable outputs. The status is shown by
two symbols on the display:
– output is disabled
– output is enabled
To disable all output (control output and 2x USB), press and hold the “OUTPUT” button (2)
for approximately 3 seconds. Press the “OUTPUT” button (2) again to enable all outputs.
Connecting a consumer load
Make sure that the load is switched off when being connected to the power
supply unit. If the load is switched on, it can cause sparking while connecting
to the sockets. This can damage the sockets, as well as the connected cables.
Disable the adjustable outputs using the the “OUTPUT” button (2).
Verify that the correct output voltage has been set on the power supply unit.
Connect the positive terminal (+) of the load with the red socket „+“ (5) and the negative
terminal (-) of the load with the black socket „-“ (4).
The connection is made using standard 4mm plugs. You can also use isolated laboratory
plugs.
