. See Appendix B and Appendix C for details.

2) Rotary knob The digital rotary knobs allow both fine and rapid adjustment of the output voltage and current. The knobs are velocity sensitive so that a slow turn of the knob allows fine adjustment of voltage or current and rapid turning of the knob quickly adjusts voltage or current over a large range.

3) Precise voltage and current measurement

Besides the precise output, the BENCH 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).

8.1 Normal Operation

8.1.1 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.

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

Until the Enable button is pressed no power will be available on the output. When the Enable 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.

19 35-000003-01 R4

To disable the output simply press the Enable button again – this will remove all voltage from

Vset v=100.0 V=88.2 i=3.500

iset i=3.122 V=88.2 i=3.122

the output.

WARNING: Because the power supply has large output capacitors it can take up to 30

seconds for the internal bleeder circuit to fully discharge the output after the Enable button has been pressed to disable the output when there is no load. Hazardous voltages may be present until the output is fully discharged.

AVERTISSEMENT: Étant donné que l'alimentation comporte de grands condensateurs de

sortie, le circuit de purge interne peut prendre jusqu'à 30 secondes pour décharger complètement la sortie après avoir appuyé sur le bouton Activer pour désactiver la sortie en l'absence de charge. Des tensions dangereuses peuvent être présentes jusqu'à ce que la sortie soit complètement déchargée.

It is possible to configure the power supply to turn the output on automatically when power is applied. See the Auto Start Setup section (8.2.3) for further details on this option.

8.1.3 Adjusting Voltage and Current The voltage and current are set using the two knobs labeled “VOLTAGE” and “CURRENT”. These knobs use high quality digital encoders rather than ordinary potentiometers. Turn the knobs 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 knob will determine the granularity of the setting. Turning at a slow rate will adjust the least most 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 Enable 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 knob 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.

8.1.4 Displaying Set Points At any time during operation, set points can be recalled by pressing the voltage or current adjustment knob. 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 knob displays the voltage set point and pressing the current knob displays the current set point.

8.1.5 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:

Short load e nd Of load wires

The Remote Sense option, when enabled, allows the power supply to correct for the resistance of any wires and connections between the power supply and the load. Most power supplies with remote sense require a second set of wires between the power supply and the load to sense the voltage at the load. The Versatile Power BENCH technology to digitally compensate for these resistances without the extra sensing wires.

Prior to using the Remote Sense option a simple load calibration must be performed. This section will detail how to enable Remote Sense and how to do the calibration required.

Once in setup mode rotate either knob until the REMOTE SENSE screen is displayed then press the Enable button. The following screen will be displayed.

Rotating either knob will alternate between the ON or OFF selection. Press the Enable knob when the desired mode is displayed.

SHORT LOAD END OF LOAD WIRES

Adjust to No rmal current I=2.33

Lead resista nce too great

It is important that a good short with heavy wire is made as failure to do this will result in a poor remote sense calibration.

Once the short is in place, press the Enable button. The following screen is an example of what will be displayed.

Now set the current to at least as much as you would expect your load to consume. More is better if your load wires are capable of handling the current. When ready press the Enable button.

The power supply will now measure the output current and the total voltage drop in the load wires and use these values to calculate the resistance of the load wires. As long as Remote Sense remains enabled the power supply will use this resistance value to calculate output voltage based on output current. It will then adjust the output voltage at the power terminals in real time to correct for the drop in the load cables.

If, during the remote sense setup, the lead resistance is so much that remote sense will not be able to operate reliable the following error screen will be displayed.

Next, the other power supplies must be put in slave mode to allow them to follow the output of the master supply.

For parallel supplies do the following:

1) On all of the slave supplies set the voltage to the maximum voltage that will be desired

in the application. Note that this voltage setting on the slaves will not be the actual

b. Also on the analog connector in the back of the unit connect pin 5 (Sharing

Output) of the master supply to pins 3 (Voltage Control Input) of the slave supply.

c. Now connect the all the positive outputs together and all the negative outputs

together.

You have now completed setup for parallel operation of the power supplies. When connected to a load, voltage and current will be determined by the master supply. Adjusting the voltage on the master will adjust the outputs on all of the supplies. As the load changes, the current will be shared between all of the supplies. Note that the current setting on the master will reflect the actual current output by the paralleled supplies divided by the number of supplies in parallel.

For series supplies do the following:

1) On the slave supply set the current to the maximum current that will be desired in the

application. Note that this voltage setting on the slave will not be the actual current output. The actual current output will be determined by the master. This setting will only determine the master.

You have now completed setup for series operation of the power supplies. When connected to a load, voltage and current will be determined by the master supply. Adjusting the voltage on the master will adjust the outputs on the slave supply. As the load changes the voltage will be shared between the supplies. Note that the voltage setting on the master will reflect the actual voltage output by the series supplies divided by two.

8.2.9 Calibration Power supply calibration allows qualified personnel to calibrate the output voltage and current and the displayed voltage and current. The process is very simple but it does require some specialized equipment. The required equipment is a calibrated volt meter and a calibrated current shunt. The current shunt must be rated for at least the full rated output current of the power supply but must not be rated at so high a current that a meaningful reading cannot be obtained at the full rated current of the power supply.

To calibrate the power supply use the following procedure:

Enter setup mode. Once in setup mode rotate either knob until the CALIBRATE screen is displayed then press the Enable button. The following screen will be displayed.

Rotating either knob will alternate between the ON or OFF selection. Press the Enable knob when the desired mode is displayed.

If the NO option is selected the system will revert to the Setup main menu. If the YES option is selected the following screen will be displayed:

41 35-000003-01 R4

following screen will now appear:

Using the Current knob, adjust the output until the external volt meter reads exactly the current displayed on the power supply display. Note that the voltage displayed on the meter will be dependent on the type of current shunt used. The voltage to be adjusted to obtain the correct current must be calculated. For example, a 10 amp, 50mV shunt will drop 50mV with 10 amps

of current. The resistance is, therefore,  = shown above the voltage meter should read  = 0.600 ∗ 0.005 = .003 .

Note also that the current displayed on the screen will vary depending on the power supply model.

When the current is exactly correct, press the Enable button and the following screen will appear:

To use a potentiometer as the control source connect one end of the potentiometer to the 3.0 Volt Reference, the other end to Ground and the wiper to the control Input. The potentiometer should be in the range of 1K to 10K ohms. Set the power supply to run from a 3 volt analog input on voltage or current or both.

CAUTION: Although these inputs are protected from ESD continuous voltages in excess of 5 volts may damage the option card. Also, noise on the inputs can affect the performance of the power supply. For long leads the user should tightly twist the wires together and consider shielding.

ATTENTION: Bien que ces entrées soient protégées contre les décharges électrostatiques, des tensions continues supérieures à 5 volts peuvent endommager la carte optionnelle. De plus, le bruit sur les entrées peut affecter les performances de l'alimentation. Pour de longues dérivations, l'utilisateur doit tordre fermement les fils ensemble et envisager un blindage.

APPENDIX C – COMMUNICATING OVER LAN

You can communicate with your power supply over the LAN connection using a Web server, or using the built in SCPI command set over UDP/IP. These methods are a convenient way to communicate with the power system without using I/O libraries or drivers. In all cases, you must first establish a LAN connection from your computer to the power system as in section 0.

Using the Web Server Your power system has a built-in Web server that lets you control it directly from an internet browser on your computer. With the Web server, you can access the front panel control functions including the LAN configuration parameters. Up to two simultaneous connections are allowed. With additional connections, performance will be reduced.

NOTE The built-in Web server only operates over the LAN interface. It requires Internet Explorer 7+ or Firefox2+, or Chrome.

The Web server is enabled when shipped. To launch the Web server:

1) Open the internet browser on your computer.

2) Obtain the power supplies IP address as described in section 8.2.7. Enter the

instrument’s IP address into the browser’s Address field to launch the Web server.

3) You will be asked for a user name and password. The default user name is “admin”

and the default password is “password”.

4) The following home page will appear:

52 35-000003-01 R4

System setup mode

Mode local

Mode remote

5) Click on the BENCH

If desired, you can control access to the Web server using password protection. As shipped from the factory, the password is “password”. To change the password, click on the LAN Settings button.

The power supply is shipped from the factory in DHCP mode so that it will automatically obtain a password from your router. Should you wish to set a static IP address you may do so from the LAN Settings page.

As shipped from the factory you may monitor your power supply using the LAN interface but not control it. In addition, a user may also adjust the power supply settings from the front panel. Should the user wish to control the power supply and lock out the front panel the power supply should be put into remote mode as described below.

1) Enter setup mode and the push the Select button on the following screen.

2) When the following screen is displayed rotate either knob to select REMOTE

Control button to begin controlling your power supply.

3) When REMOTE is displayed press the select button. Note that when in remote mode

all menu selections other than REMOTE or LOCAL are suppressed.

4) Exit and Save the setting.

Controlling your power supply using TCP/IP or UDP/IP Your power system has built-in TCP/IP and UDP/IP interfaces that allow you to control the power supply using the full supported SCPI command set.

To use either interface use the IP address as set up in previous chapters of this manual and use port 8003 for TCP and 8005 for UDP. Follow each SCPI command with a line feed. A complete description of the SCPI command set is in the supplied Programming Manual.

APPENDIX D – RACK MOUNT OPTION

Installation of the rack mount kit is a simple procedure but damage to the power supply can occur if it is not done properly. Please follow the steps carefully.

1) Unplug the power supply.

2) Remove the rubber feet as shown in the figure below.

Retain the feet and screws in case they are needed later.

CAUTION: If the feet are replaced with the incorrect screws damage to the power supply can occur. Be sure to use 6-32 screws with 3/8 inch length.

54 35-000003-01 R4

3) Remove the screws from the front panel as shown in the figure below.

CAUTION: When the screws are removed from the front panel the panel will be loose. Do not let the panel fall away from the power supply as the interconnect cables may come loose or be damaged. Hold the panel up against the power supply at all times.

4) Hold the rack mount plate in front of the power supply front panel and secure with the

new screws provided with the rack mount plate. Do not use the original screws as they will be too short. See figure below:

55 35-000003-01 R4

5) If a second power supply is to be mounted on the rack mount kit begin with Step 2

above. If a blank panel is to be mounted in place of a second power supply use provided panel and screws. See figure below.

APPENDIX E – ERROR MESSAGES

Overcurrent trip Enable to re set

Overvoltage trip Enable to re set

Overpower tr ip Enable to re set

This appendix describes the various error conditions that can occur in the power supply. There are two groups of error conditions; first, errors that involve exceeding of limits set by the operator or that are hard programmed into the unit, second, errors involving a failure within the power supply.

The first group of errors – errors caused by limits set by the user or the factory are described below:

The “OVERCURRENT TRIP” error is caused by exceeding the current set by the “OCP SET” command. If the current limit value is set to below the “OCP SET” value this condition will rarely if ever occur. If the “OCP SET” value is below the current limit value then this condition will occur whenever the load resistance is low enough to allow the set value to be exceeded without going into voltage. To reset the power supply simply press the ENABLE button.

The “OVERVOLTAGE TRIP” error is caused by exceeding the voltage set by the “OVP SET” command. If the voltage limit value is set to below the “OVP SET” value this condition will rarely if ever occur. If the “OVP SET” value is below the voltage limit value then this condition will occur whenever the load resistance is high enough to allow the set value to be exceeded without going into current limit. To reset the power supply simply press the ENABLE button.

The “OVERPOWER TRIP” error is caused by exceeding the power set by the “OPP SET” command. To reset the power supply simply press the ENABLE button.

57 35-000003-01 R4

Temperature err Enable to re set

Output error Enable to re set

12v bias err Enable to re set

3.3v bias er r Enable to re set

The “OVER TEMPERATURE” error is caused by exceeding the maximum operating temperature of the power supply. To reset the power supply simply press the ENABLE button. If the power supply is within its temperature limits when the ENABLE button is pressed the supply will return to normal operation. If the supply is still outside its operating limits the error will persist. If this error reoccurs after a cool down period check to be sure that there is at least one inch of clearance around all the vents.

The second group of errors – errors involving a failure within the power supply are described below:

The “PWM ACTIVATE ERR” error is an internal error of the power supply. This is usually caused by a component failure. To reset the power supply simply press the ENABLE button. If the error reoccurs the power supply must be repaired by the factory.

The “12V BIAS ERR” error is an internal error of the power supply. This is usually caused by a component failure. To reset the power supply simply press the ENABLE button. If the error reoccurs the power supply must be repaired by the factory.

58 35-000003-01 R4

The “3.3V BIAS ERR” error is an internal error of the power supply. This is usually caused by a

Pfc failure Enable to re set

Hs temp error Enable to re set

component failure. To reset the power supply simply press the ENABLE button. If the error reoccurs the power supply must be repaired by the factory.

The “PFC FAILURE” error is an internal error of the power supply. This is usually caused by a component failure. To reset the power supply simply press the ENABLE button. If the error reoccurs the power supply must be repaired by the factory.

The “HS TEMP ERROR” error indicates an overtemperature of the main heatsink. This is usually caused an ambient temperature over 40C. To reset the power supply simply press the ENABLE button. If the error reoccurs and the ambient temperature is within specifications the power supply must be repaired by the factory.

The “FAN STALL ERROR” indicates that the fan is not running at the expected speed. This is usually caused by an obstrction in the fan or by a failed fan. To reset the power supply simply press the ENABLE button. If the error reoccurs the power supply must be repaired by the factory.

59 35-000003-01 R4

SELF-TEST ERRor Enable to re set

COMM TIMEOUT Enable to re set

On power up the power supply runs a check on several internal systems to make sure all is working well prior to power up. The “SELF-TEST ERROR” error is an internal error of the power supply that can occur during initial power on when the self-test is performed. The unit must be sent in to the factory for repair.

“COMM TIMEOUT” indicates that one of the power supplies communication ports has not responded in a timely manner. To reset the power supply simply press the ENABLE button. If the error reoccurs the power supply must be repaired by the factory.
