Output Setup
Basic Programming
The XMP 2600 has a host of features that enhance its usage. This section describes the
parameters involved in setting-up the outputs of the XMP 2600 Power Modules.
Power Module output rating
Overview of
output setup
parameters
Each XMP 2600 Power Module is defined by its output rating (the amount of voltage and
current it can deliver). The user can use a Power Module up to its output rating, named
Vmax and Imax.
Output voltage can be programmed in the range 0 to Vmax and output current can be
limited to a value in the range Imin to Imax.
Vmax, Imax and Imin are the Power Module output rating – they cannot be programmed,
only read (for reference) using queries like:
program
range
Imin
Imax
V
VMAX? <ch>
Vmax
IMAX? <ch>
IMIN? <ch>).

Output program limits
Some times it might be desirable to limit the maximal values that may be programmed for
the output’s voltage (Vlim) and/or current (Ilim) settings. Circumstances like this may
rise when, for example, using a 36V Power Module with a load that tolerates voltages up
to 14V only. Setting a limit on the ability to program the output voltage of a Power
Module ensure that no higher output voltages will be produced, by accident.
Placing limits on output programming (Vlim and Ilim) is achieved using the commands:
VLIM <ch>,<value>
program
range
Imin
Imax
Vmax
V
and
Vlim
ILIM <ch>,<value>
where <value> is limited by either Vmax or Imax and
defaulted to Vmax and Imax.

Ilim
Output protection
Each Power Module of the XMP 2600 has Over Voltage and Over Current protection
settings. When the output’s voltage or current exceed the protection threshold the Power
Module is shut down and a fault event is generated.
The protection thresholds may be programmed by the user (manual mode) or set
automatically by the XMP 2600 (automatic or tracking mode which is the default)
whenever a new output setting (see bellow) is programmed.
Determining the way protection values are set is done using the command:
PROT <ch>,<mode>
where <mode> can be either 0 for manual or 1 for automatic.
When using the manual protection setting mode, use the following commands to set the
protection thresholds (OVset and OCset):
OCset
range
OVset
range
Imin
Imax
Vmax
V
OVSET <ch>,<value>
and
Vset
OCSET <ch>,<value>
