Using the power supply
7.1
Defining operation parameters
Setup operation mode +
The way of adjusting the set values, which operation mode is
used, how the unit shall react after the mains has restored or
the behaviour of the unit after an overtemperature error can be
configured here.
U/I/P or U/I/R operation mode
Setup op. mode
Default:
U/I/P
= U/I/P
The power stage is controlled by voltage, current
and power set values (only models from 1kW and
with power regulation)
= U/I
The power stage is controlled by voltage and
current (models up to 640W)
= U/I/R
The power stage is controlled by voltage,current
and resistance set values and a settable, but not
adjustable power set value (only with unlocked
option „internal resistance control“)
Notice
: the U/I/R operation mode can only be used after it has
been unlocked in the
Options
menu. The unlock code can
be purchased at the sales company who sold the power sup-
ply. The serial number of the unit is required to be told when
purchasing the option, because the unlock code is related to it.
In U/I/R operation mode you can add an adjustable internal
resistance to this voltage source.
The voltage set value is related to the off-load voltage U
o
of the
power supply. The off-load voltage is reduced by the product
of I
act
Ri
set
. The resulting voltage is calculated as follows:
Iset, Pset
U
set
= (U
0
- I
act
•
Ri)
Clarification:
CR
This is shown in the display while the internal resi-
stance control is active and U/I/R operation is set.
The internal resistance Ri
set
is displayed instead of the power
P
set
while U/I/R mode is active. However, the actual value of
the power is still displayed.
Reactivation after an overtemperature error
OT disappear
Default:
auto ON
=OFF
The power supply output remains switched
off, even if the unit has already cooled down.
The error...
OT
(overtemperature) is displayed as an alarm.
= auto ON
The power supply is automatically switched
on after the unit has cooled down below the
overtemperature shutdown limit.
The error...
OT
(overtemperature) is then displayed as a
warning.
Warnings as well as alarms are only deleted from the display
after they have been acknowledged (see also „6.13 Alarms,
Output state after „power on“
Power ON
Default:
OFF
= OFF
The power supply output remains switched off
after the mains voltage returns or after the unit
was switched on.
= restore
The power supply output is set to the state it
had before a mains voltage loss occured or
before the unit was switched off. In case it was
ON when the unit was switched off, it will also
be ON when the unit is switched on again.

Resistance values (red) only at unlocked option U/I/R.
Power values (green) only with models from 1kW
With the parameter
Accept set value =
from preset list
you can switch from the normal set values (eg. adjusted by the
rotary knob) to one of the predefined sets or switch between
predefined sets. You can actually „jump“ between set values
with this option.
