How do I connect the DP832 to achieve +/-30V on Channel 1 and Channel 2?

Posted on: December 16th, 2020 by Doug Lovell
The DP832 is a triple output power supply. CH1 and CH2 are +30V supplies, and CH3 is a 5V supply. 
To configure the instrument as a +/-30V or lower, you can use the instrument ground plug located on the front panel: 
  

–    Select which channel you want to be + and which you want to be – (in this note, we will select CH1 as -, CH2 as +) 
NOTE: The jumper wires connected to the DP832 ground  must use wire rated for 9A or greater to prevent damage or a possible fire hazard. 
 
–    Connect the power supply up as follows (we are including CH3 here) 

 
–    Configure the channels for the proper voltage, current, and limits that they require. 
 
NOTE: CH1 true polarity will be negative (-) with respect to the DP832 Ground Connection, even though the programmed voltage will indicate positive (+) 
 
–    Enable the power supply outputs by pressing the ON/Off buttons for each channel 
–    To make operation easier, you can also activate Tracking between Channel 1 
and Channel two by pressing  Utility > System > Track Set > Set Track to  
“Synchronous”. This will allow you to adjust the output value for Channel 1 
    and Channel 2 will follow.      

For floating connections (without earth ground) 

–    Select which channel you want to be + and which you want to be
            – (in this note, we will select CH1 as -, CH2 as +) 
Connect the power supply up as follows (we are including CH3 here) 

 
  
 
NOTE: The jumper wires connecting CH1 +, CH2 –, and CH3 – must use wire rated for 9A or greater to prevent damage or a possible fire hazard. 
Configure the channels for the proper voltage, current, and limits that they require. 
 
NOTE: CH1 true polarity will be negative (-) with respect to the DP832 Ground Connection, even though the programmed voltage will indicate positive (+) 
 
–    Enable the power supply outputs by pressing the ON/Off buttons for each channel 
–    To make operation easier, you can also activate Tracking between Channel 1 and Channel two by pressing  Utility > System > Track Set > Set Track to  “Synchronous”. This will allow you to adjust the output value for Channel 1 and Channel 2 will follow.

DP700 Trigger output operation

Posted on: December 16th, 2020 by Doug Lovell
The DP700 series power supply can receive a trigger to enable the output of the supply. Pin 8 of the RS232 interface on the rear panel is used for trigger input,


When a low level (<1.4V) is received the channel output will be turned on and when the level is equal or greater than 1.4V output will be turned off.

To turn of the external trigger capability press System to enter the system utility interface. By default, the “Setting” tab is selected. Press the Up/Down arrow key to switch the parameter focus to “Trig In”, and press the Left/Right arrow key or the knob to enable the trigger input function.

DP700 transient voltage on power up

Posted on: December 16th, 2020 by Doug Lovell

The DP700 series power supply will show a transient voltage on the outputs when the power supply is powered up. Typically the transient voltage will show approximately 400mV p-p over a 200us duration. 

The DP700 power supplies do not have output relays to to  enable output after the power supply has been  turned on and has stabilized. It is recommended that connections be made to a device after the power  supply has been powered  up if  you are working with circuitry that is sensitive to this transient voltage.

Confirming what options are installed on the DP800 series

Posted on: December 16th, 2020 by Doug Lovell

Options can be added to the non “A” version of the DP800 power supplies to give them the same capabilities as the A version power  supplies.

To see what options are currently installed on your power supply  press Utility key and go to page 2. Now press Option to see the status of the six listed options. If Official is listed with an option the power supply has that option turned on. 

Non A version power supplies will continue to have the monochrome display even if all options are installed:

How to Load a Timer File

Posted on: December 16th, 2020 by Doug Lovell
The DP800 allows the user to create timer functions either directly on the instrument through the timer interface or by loading a timer file onto the instrument.  To load the timer file press the Timer button then press Timer Set and then arrow over to the second page of the Timer Set menu, on this page of the menu you will be able to save a timer file either to the instrument or to a thumb drive. To load a timer file press the Read button and then select which browser the file is saved in and then select the file.  Once the file has been selected press the Read button.

Timer operation with the DP700 series power supply

Posted on: December 16th, 2020 by Doug Lovell
The DP700 series power supply provides a timer function. When the timing output is enabled, the instrument will configure the output voltages and currents based on the preset timer parameters. The edited timer parameters are allowed to be saved to the internal non-volatile memory (NVM), and can be recalled if necessary.

Timer is an optional function. If you want to use the timer function the option will need to be purchased and installed.

Pressing the Timer keypad button will bring up the screen below.





Output Groups represents the steps or groups that will be used. In the example above only one group is specified to  run as shown in column 1. So  Group 1 will output a voltage of  1 volt at 1 amp for  1 second. All other columns are grayed out. You can specify a maximum of 2048 groups.

One Cycle is one sequence of Groups. So you can repeat a sequence of Groups by setting the Cycle setting between 1 and 99999. You can also save and restore timer setups from this  menu page as well as set the End State. The End State can be set to last or off.
 
Trigger Mode can be specified  as Single or Auto. When Single is specified the power supply will output one group at a time and will increment to the next group when the OK button is pressed. When Auto is selected the complete sequence of groups will be run.

End State can be selected to Output Off or Last. With Output Off selected the power supply will turn the output off when the last group is completed. When Last is selected the power supply will maintain the settings of the last group that is completed.

To start the sequence of groups press the On/Off button.

Timer operation with the DP800 series power supply

Posted on: December 16th, 2020 by Doug Lovell

When the timer is enabled the power supply will output preset voltage and current values at time increments you specify.

Press Timer and then Timer Set to see the screen below. The columns 0-5 represents steps or groups that will be output at the Set time in seconds. So for this example only column 0 will be output since the Group field has been set to 1.

The channel currently selected is displayed in the status bar. Press the channel selection keys at the front panel to select the channel you wish to program. Then press Parameter to select voltage current and time duration for each group. Groups 0 through 5 can be seen on the screen and you can program as many as 2048 Groups.

Once you have programmed the voltage, current and time for each Group then go to page 2/3. Here you can specify Cycles. One Cycle is one sequence of Groups. So you can repeat a sequence of Groups by setting the Cycle setting between 1 and 99999. You can also save and restore timer setups from this  menu page as well as set the End State. The End State can be set to last or off.

From menu page 2/3 increment to 3/3 and then press the left arrow at the bottom of the display to  get to the Timer and Delayer interface:

To enable the timer and output the programmed levels first turn Timer On and then press the On button of the channel  that has been programmed. Once turned on the power supply will output each group that has been programmed.

The power supply also has a collection  of templates  that will output voltage and current to a set pattern. They include  Sine, Pulse, Ramp, Stair Up, Stair Dn, StairUpDn, Exp Rise and Exp Fall.
