Black or Green Terminal on a Power Supply
Our power supplies are isolated power supplies. So when you connect to the black negative terminal you have connected your DUT to an isolated channel. Where as if you connect to the green terminal you are connecting your DUT to ground which will no longer have the power supply act as an isolated supply.
DP800 Reaction Time for OVP, OCP and OPP being Exceeded
The image below shows how quickly the DP800 will turn off its output when it detects that OVP, OCP or OPP has been exceeded. The instrument below shut off its output power 790ms after it started creating the higher voltage.
How do I connect the DP832 to achieve +/-30V on Channel 1 and Channel 2?
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.Confirming what options are installed on the DP800 series
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:DP800 transient voltage on power up
The DP800 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 DP800 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.How to Load a Timer File
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 DP800 series power supply
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.
Lock and Unlock Capability of the DP800 series
The DO800 series allows you to easily lock and unlock the instrument’s front panel by pressing and holding on the OK button in the bottom right hand corner of the front panel. When the instrument is locked the only buttons that are fully function are the individual channel On/Off buttons otherwise the rest will not respond. To unlock the instrument, you need to press and hold the OK button just like with locking the instrument.
The instrument also comes with the ability to implement a password requirement when Unlocking the instrument, it will not require a password to lock the instrument. To enable this feature press Utility -> Systemv – > Arrow over to page two -> Key Lock. When this feature is turned on the instrument will require the user to enter 2012 before the instrument will be unlocked.
How to install DP800 Option Licenses
DP800 series power supply provides the following options:
High Res: 1mV/1mA Resolution option for the DP800 Family
