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).

7. Operating Instructions

7.1 Normal Operation

7.1.1 Power On

Connect the power input to the appropriate AC voltage source. Turn the Power Switch to the ON (I) position. On power up the supply will execute a self-test. During the self-test the display will show the voltage and current capabilities of the supply and the software revision.

7.1.2 Enabling Output

After Power On the output of the power supply will be disabled until the output on/off button is pushed. The screen will display the output status, the set points currently in force, and control mode (e.g., Local, Remote).

 

 

OFF

Ioc

V=100.0

i=3.500

Until the output on/off button is pressed no power will be available on the output. When the output on/off button is pressed the output will be turned on and the display will show the output status, the operating mode, and the actual output voltage and current.).

The power supply will always be in either voltage mode (VMODE) or in current mode (IMODE or PMODE). 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.

WARNING: 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.

7.1.3 Adjusting Voltage and Current

The voltage and current are set using the two controls labeled “VOLTAGE” and “CURRENT”. These controls use high quality digital encoders rather than potentiometers. Turn the controls clockwise to increase a setting or counter clockwise to decrease a setting. The encoders allow fine or coarse control of the voltage or current setting. The speed at which you turn the controls will determine the granularity of the setting. Turning at a slow rate will adjust the least significant digit of the parameter being adjusted. Turning more rapidly allows coarse control to allow rapid changing of voltage or current.

If the output is disabled while an adjustment is being made the voltage and current setting will be shown on the normal output off display. The new settings will take effect when the output on/off button is pressed.

If the output is on while an adjustment is being made the voltage or current will change in real time as the control is turned. A special screen will be displayed during the adjustment as shown below. The screen will revert to the normal operating screen as soon as the adjustment is complete. In the screens below the actual real-time output voltage and current is shown on the bottom line and the set voltage or current is shown in the top line. In the cases below the power supply is current limiting as the actual current matches the set current.

Note that the actual voltage or current is load dependent and, therefore, may not match the displayed set point.

7.1.4 Displaying Set Points

At any time during operation, set points can be recalled by pressing the voltage or current rotary control. This action displays the set points in the same manner as they would be displayed during a set point adjustment but without actually changing anything. Pressing the voltage control displays the voltage set point and pressing the current control displays the current set point.

7.1.5 Adjusting Over Voltage, Over Current and Over Power Protection.

The over voltage protection (OVP), over current protection (OCP) and over power protection (OPP) features limit the maximum output current and voltage to avoid damages to the unit under test (UUT). OVP and OCP may be set as shown below or may be changed via the setup menus. OPP may only be changed in the setup menus. Note that Over Voltage and Over Current protection can also be adjusted in the Setup menu – section 8.2.5.

If OVP, OCP, or OPP is set to maximum that protection will be disabled. Note: OVP, OCP, and OPP cannot be set to more than 10% over the maximum rating of the power supply.

To adjust OVP press and release Voltage. The following screen will appear:

OVP set

OVP = 12.00

Ioc i=3.500

Turn the Voltage control to adjust the OVP setting. When the desired setting is displayed press the output on/off button and the supply will revert to its previous state.

To adjust OCP press and release the CurrentOcPcontrolset. The following screen will appear:

OcP = 2.500

Turn the Current control to adjust the OCP setting. When the desired setting is displayed press the output on/off button and the supply will revert to its previous state.

If, during operation, any of these set points is exceeded the appropriate screen will be displayed as below.

Overvoltage trip Enable to reset

Overcurrent trip Enable to reset

Overpower trip Enable to reset

Pressing Output On/Off when any of the trip screens are displayed will reset the trip and put the power supply back in idle

mode. The following screen will be displayed.
