Overview of output setup parameters

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

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:

VMAX? <ch>

V

 

Vmax

 

 

program

IMAX? <ch>

 

 

range

 

 

IMIN? <ch>).

 

I

 

Imin

Output program limits

Imax

 

 

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>

V

 

and

Vmax

 

 

Vlim

 

ILIM <ch>,<value>

program

 

where <value> is limited by either Vmax or Imax and

range

 

 

I

defaulted to Vmax and Imax.

Output protection

 

Ilim

 

 

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):

 

V

 

 

OVSET <ch>,<value>
