Page 67: Set V, I, And P Limits
Set V, I, and P The voltage, current and power setpoints can be limited to less than the supply rating range to match the tolerance of connected equipment or any other criteria you may Limits have. Once the limits have been changed from the supply’s default rated output, settings outside this range are no longer accepted. -
Page 68: Triggering Commands
Auto Sequencing Triggering Triggers are event-driven signals that instruct power supplies to change their output. Triggering provides a method to control changes in the power supply’s output and to Commands program several power supplies to react at the same time. Triggering is useful in manufacturing processes where power requirements change as the machinery performs different operations. -
Page 69: Slew Rate
Slew Rate The slew rate is calculated as a function of change in the output voltage and a given time interval. The maximum slew rate is 1% rated voltage/150us. The slew rate is saved upon power off and restored at power on. Output ON/OFF and shutdown are not affected by the programmable slew rate. -
Page 70: Identification Query
Auto Sequencing Example: Set a slew rate of 100V/10s for a 100V-60A power supply. This slew rate is 1V/0.1s, which is within the acceptable range. Send the commands: “:VOLT:SLEW:STEP 1”, and “:VOLT:SLEW:INT 100ms” Using smaller steps will result in a smoother curve. Identification The identification query command returns a string that states the manufacturer, model, serial number, and firmware revision. -

Page 91: Section 5. Current Sharing
Section 5. Current Sharing Overview CAUTION Always exercise caution when using the current sharing feature. If a unit is set to Master or Slave, it will be locked out of local operation. Current sharing units will have their outputs disabled if one power supply enters shutdown. The current sharing function allows power supplies to current share between units connected in parallel. -
Page 92: Theory Of Operation
Overview Theory of Power supplies may be connected in parallel to supply a large current to a load. Typically, because of differences in the load connections, each power supply may Operation provide different amounts of current to the load. When multiple power supplies are configured for current sharing, the master supply will make minute changes to the slave’s voltage and current to equalize the current draw from each. -
Page 93: Operation
Operation Once a current sharing network is setup, you may adjust the voltage setpoint on the master. The master will automatically adjust the setpoints of the slave units to equalize the current output of all units. You may also disable or enable the output of the master, automatically disabling or enabling the output of all slaves. - Page 94 Current Sharing Operation Operating Manual for Multichannel Functionality (GPIB-M)

Page 101: Understanding Scpi Commands
Understanding SCPI Commands SCPI SCPI is an ASCII-based command language designed for use in test and measurement equipment. The command structure is organized around common Command roots, or nodes, which are the building blocks of SCPI subsystems. An example of a Hierarchy common root is CALibration, and some of the commands that reside in the CALibration subsystem are shown below. - Page 102 Understanding SCPI Commands The following punctuation is sent with the command string: Colons (:) separate command keywords from lower-level keywords. • For example, CAL:CURR:STAT. Blank spaces separate command keywords from parameter values. • For example, CURR 0.1. Commas separate parameters from each other when more than one parameter is •...
