12. Miscellaneous

12.1 Accessories and option

Note
Details about options and accessories are available in sepa-
rate user guides.
Following accessories are optionally available:
a) USB-to-Analog interface UTA12
Galvanically isolated remote control via USB (on PC side) and
the device internal analog interface.
b) Option IF: Digital interface cards
Pluggable and retrofittable, digital interface cards for USB, RS232,
CAN, GPIB/IEEE (SCPI only), Ethernet/LAN (SCPI) or Profibus.
c) Option IF: Analog interface card
An extended, 25 pin, galvanically isolated analog interface is
available. It is also pluggable and retrofittable.
Following options are available:
a) Option HS: High Speed Ramping (models from 1 kW)
Increased dynamics of the output voltage by reduced output
capacity. It must be pointed out, that other output related values
also increase!
Note
This is a permanent modification which is not switchable.
b) Option IR: Internal resistance regulation
This option can be purchased subsequently and is unlocked with
a code number in the device's setup menu.
After it is unlocked, the user can choose between U/I/P or U/I/R
operation. The power set value will not be adjustable in U/I/R
mode, it is then only defined as a limit in the device settings.
Note
It will eventually be required to update the device firmware
before the option can be unlocked. Ask your supplier!

12.2 Firmware update

A firmware update of the device should only be done if the de-
vice shows erroneous behaviour or if new features have been
implemented.
In order to update a device, it requires a certain digital interface
card, a new firmware file and a Windows software called „Update
tool".
These interfaces are qualified to be used for a firmware update:
• IF-U1 (USB)
• IF-R1 (RS232)
• IF-E1 (Ethernet/USB)
• IF-PB1 (Profibus/USB)
In case none of the above interface types is at hand, the device
can not be updated. Please contact your dealer for a solution.
The update tool and the particular firmware file for your device are
obtainable from the website of the device manufacturer, or are
mailed upon request. The update too will guide the user through
the semi-automatic update process.

12.3 Option: Internal resistance

The unlockable option „internal resistance" adds an imaginary,
variable resistor to the internal voltage source of the power sup-
ply. After this option has been unlocked, the „R mode" or U/I/R
mode can be activated in the menu
(see section 7.1) by switching from U/I/P resp. U/I to U/I/R. The
voltage set value is related to the off-load voltage U
supply. The off-load voltage is reduced by the product of I
The resulting voltage is calculated as follows:
U = (U - I • Ri)
