4. Preface
4.1 Product Summary
The PLS600 is a programmable DC power supply with single output that offers a maximum power output up to 600 watts. With
12-bit D/A & A/D converters embedded, the power supplies come with the capability of reporting voltage and current very
accurately.
The PLS600 series provides convenient digital rotary controls for voltage and current adjustment. The power supplies also come
with rear ports that allow remote control via USB, thernet, and analog control inputs. The USB and thernet inputs are SCPI
compliant and have LabView drivers available on the National Instruments website. See Appendix A and Appendix B for details.
The PLS600 series is also LXI certified, details for using this interface can be found in the Programming Manual.
The PLS600 series also provide a sophisticated scripting ability that allow the user to write programs and upload them to the
power supply. The PLS600 will then execute the programs on command. Details can be found in the PLS600 scripting language
manual.
4.2 Features
1. Output Voltage & Current
2. Rotary Controls
The digital rotary controls allow both fine and rapid adjustment of the output voltage and current. The controls are velocity
sensitive so that a slow turn of the control allows fine adjustment of voltage or current and rapid turning quickly adjusts voltage
or current over a large range.
3. Precise voltage and current measurement
The PLS600 series also offers the capability to measure voltage & current accurately (read back), saving users the extra
expense and space for extra measuring instruments. This capability is available from the display or the readings may be read
into the controlling device.
4. OVP (over voltage protection), OCP (over current protection) and OPP (over power protection) functions
The over voltage protection (OVP), over current protection (OCP) and over power protection (OPP) features limit the maximum
output current and voltage to avoid damage to the unit under test (UUT).

The power supply will always be in either voltage mode (VMOD ) or in current mode (IMOD or PMOD ). This state is
dependent on the power supply settings and the load. When in current mode the display will be as shown below.
To disable the output simply press the output on/off button again – this will remove all voltage from the output.
WAR I G: Because the power supply has large output capacitors it can take up to 30 seconds for the internal circuit to fully
discharge the output after the output on/off button has been pressed to disable the output when there is no load.
Hazardous voltages may be present until the output is fully discharged.
It is possible to configure the power supply to turn the output on automatically when power is applied. See the Auto Start Setup
section (7.2.3) for further details on this option.
