Options and modifications:
Analog programming
Analog programming:
With this option the output volt-
age and current of the power
supply can be set via analog
voltages (0-10V) or by external
potentiometers. Monitor signals
of voltage and current (0-10V)
available on the programming
terminal. An external "ON"-
command enables the regula-
tion loop.
Selection of manual operation
or external programming is pos-
sible by a switch on the front
panel. This option is also availa-
Many FuG- power supplies are
available which differ from the
standard design or equipment.
On this pages we highlight
some of the most common
options and modifications. Oth-
er customer-specific units hav-
ing different technical data,
different mechanical construc-
tion, alternative customer de-
fined interfaces or with extend-
ed features are available even
for single piece orders.
ble as a retrofit set for later up
gradation of your unit.
Usually the "0V" of the pro-
gramming voltage is connected
to one of the outputs of the unit.
If this is not wanted, the unit
may be equipped with floating
analog programming.
For this version:
 Isolation max. 2kV DC with
respect to the unit output,
30V DC with respect to
ground.
On request we can also supply
a fibre optic option with isolation
capabilities up to 200kV and
more.
For most models, the floating
analog programming can be
installed later at our site.

For single types of equipments, deviations from this configuration are possible (especially for HCN7E, HCB, NLB and custom-designed equip-
ment). In these cases the equipment description is valid.
For proper function of the analog programming at least pin 12 (Output ON/OFF - link to 0V) and both pins 8 and 15 (set values ≠ 0) have to be
connected. Using external set value signals, the "0V" line also has to be connected.
On request we also deliver a complete remote control with indicating instruments and set-point potentiometers in a separate case (cable length to
10m), matching to the analog programming.
