Operating the device
5.4
When adjusting the set values of voltage (U) and current (I),
a rule becomes active where both set values adjust each
other in order to not exceed the max. power of the device

and that limit is reached, the OCP will have priority and
switch the output off.
Adjusting values manually can be done in fine or coarse
steps. Switching is done by pushing the corresponding
knob. In normal operation, fine adjustment mode is default.
Coarse adjustment can be activated and will automatical-
ly return to fine adjustment mode, if no value has been
changed for more than 4 seconds.
Following step widths apply in dependency of the nominal
values (also refer to technical specs):
5.5 Control panel lock (LOCK)
The control panel LOCK is intended to prevent unintentional
use of the pushbuttons and knobs. LOCK ist activated or
deactivated using the preset button.

If the output is off and the voltage set value is increased,
the current set value will automatically decrease some-
time or if the current set value is increased, the voltage
set value will automatically decrease sometime. For the
output being on, it will behave like in normal operation.
a) If the output is on and constant voltage regulation is
active (CV in the display), then the current set value can
only be increased to a certain limit which is defined by
the formula maximum power = voltage set value * current
set value and depending on the voltage set value.
b) If the output is on and constant current regulation (CC
in the display) then the voltage set value can only be in-
creased to a certain limit which is defined by the formula
maximum power = voltage set value * current set value
and depending in the current set value.
The OVP threshold can be set to lower than the voltage

Activation is done by pushing the preset button three
times until the display shows following:

A countdown will be running. During this countdown you
have two options:
a) You wait until the countdown has finished. After this, the
control panel LOCK is active.
b) You push the button once again and abort the count-
down. LOCK is then not activated.
Deactivation is done by pushing button Preset again. The
countdown will start again. If it runs out, LOCK remains
active. If the countdown is aborted by pushing the button
again, LOCK will be deactivated.

6.1 Switching on by power switch
The power switch is located at the front. After the device
is started, following situation will be set:
• the output is off
• the current set value is set to 5% and the voltage set
• the set values of overvoltage and overcurrent protection
Any condition like REMOTE or LOCK is reset.
6.2 Overvoltage
An overvoltage error can occur due to an internal defect
(output voltage rises uncontrolled) or by a too high voltage
from external.The overvoltage protection (OVP) will switch
off the output and indicate the error in the display by the
text „Error“. This error has to be acknowledged first by the
On/Off pushbutton. Then the display will change to normal
display again. Also see section 5.2.2.
External voltages higher than 120% nominal voltage at
the output must be avoided, or else internal compon-
ents of the device might be destroyed!
If the cause of the overvoltage is removed, the output can
be switched on again.
