PS 2000 B Triple Series
1.9 Construction and function
1.9.1 General description
The laboratory power supplies of the series PS 2000 B Triple are very compact and rugged devices and incorpo-
rate interesting features within small dimensions. The contactless design makes them ideally suited for operation
in schools, educational facilities, workshops or laboratories.
The Triple in the name comes from the three featured, galvanically isolated DC outputs. Two of them are fully
adjustableregardingvoltageandcurrent,whilethethirdoneisanauxiliarysupplywithxedvoltage(3-6V)for
small power needs.
Apart from standard functions of power supplies the user can lock pushbuttons and knobs against unintentional
useordenethresholdsforanautomaticoutputcut-o󰀨incaseofovercurrentorovervoltage.
A feature called Tracking allows for synchronous control of the set values of both adjustable outputs, which is
especiallybenecialwhenoperatingthetwooutputsinparallelorseriesconnection.
All models feature a built-in USB interface, which can be used to remotely control and monitor the device by a PC.
1.9.2 Scope of delivery

The device is delivered with an USB stick that contains the Windows remote
control software EA Power Control. In its basic version it can already control
multiple PS 2000 B devices in separate windows and also run a semi-auto-
matic control called Sequencing, plus record data (Logging). The optional
licenseunlockstwoadditionalfeatures.TherstisMultiControl,anappthat
allows for the parallel and simultaneous remote control of up to 20 units in
one window, plus Sequencing for any number of units or groups of units. The
second feature is the Graph, an XY plot that records device data (set values,
actual values) visually.

2. Installation & commissioning
2.1 Storage
2.1.1 Packaging
It’s recommended to keep the complete transport packaging for the lifetime of the device for relocation or return
to Elektro-Automatik for repair. Otherwise the packaging should be disposed of in an environmentally friendly way.
2.1.2 Storage
In case of long term storage of the equipment it’s recommended to use the original packaging or similar. Storage
must be in dry rooms, if possible in sealed packaging, to avoid corrosion, especially internal, through humidity.
2.2 Unpacking and visual check
After every transport, with or without packaging, or before commissioning, the equipment should be visually
inspected for damage and completeness using the delivery note and/or parts list (see section «1.9.2. Scope of
delivery»). An obviously damaged device (e.g. loose parts inside, damage outside) must under no circumstances
be put in operation.
2.3 Installation
2.3.1 Safety procedures before installation and use
• Before connecting to the mains ensure that the connection is as shown on the product label.
Overvoltage on the AC supply can cause equipment damage.
• In case the load is also a voltage source (motor, battery etc.) make sure before connecting it,
that the source can not generate a voltage higher than 1.1 * rated voltage of your particular
device model or install measures which can prevent damaging the device by overvoltage from
outside.
2.3.2 Preparation
Mains connection for a PS 2000 B series device is done via the included 1.5 meters long 3 pole mains cord.
DimensioningoftheDCwiringtotheloadhastoreectthefollowing:
• Thecablecrosssectionshouldalwaysbespeciedforatleastthemaximumcurrentofthe
device.
• Continuous operation at the approved limit generates heat which must be removed, as well as
voltage loss which depends on cable length and heating. To compensate for these the cable
cross section should be increased and/or the cable length reduced.
2.3.3 Installing the device
• Select the location for the device so that the connection to the load is as short as possible.
• Leavesu󰀩cientspacebehindtheequipment,minimum10cm,forventilationofwarmairthat
will be exhausted
• Never obstruct the air inlets on the sides!

2.3.4 Connection to DC loads
• Connection of loads which are also voltage sources and can probably generate voltages
higher than 110% nominal of the device model isn’t allowed!
• Connection of voltage sources with reversed polarity isn’t allowed!
The DC output is located on the front of the device and isn’t protected by a fuse.
The cross section of the connection cable is determined by the current consumption,
cable length and ambient temperature.
The DC output sockets are so-called safety sockets which allow for the use of so-
called safety plug where the protective plastic sleeve is either rigid or retractable.
Alternatively, standard laboratory cables with 4 mm Büschel plugs can be used.
Those are not suitable for currents higher than 10 A. It has to be pointed out that
the outputs 1 and 2 have identical ratings while output 3 can only deliver a small
current and power.
For cables up to 5 m and average ambient temperature up to 50°C, we recommend:
up to 3 A: 0.75 mm² up to 10 A: 1.5 mm²
per lead (multi-conductor, insulated, openly suspended). If the cables are long then
the cross section must be increased to avoid voltage loss and overheating.
2.3.5 Grounding of the DC outputs
The metal socket in proximity to output 1 is internally wired to PE and can be used to ground one of the DC output
poles of all three outputs by direct connection or it can be used to ground hardware which is connected as load.
2.3.6 Connecting the USB port
The device features an integrated USB port on the front. It can be connected to a PC or other suitable control
applications (PLC) via a standard USB cable (not included), in order to remotely control and/or monitor the unit.
2.3.6.1 Driver installation (Windows)
On the initial connection with a PC the operating system will identify the device as new hardware and will try to
install a driver. The required driver is for a Communication Device Class (CDC) device and is usually integrated in
current operating systems such as Windows 7 or 10. But it’s strongly recommended to use and install the included
driver installer (on USB stick) to gain maximum compatibility of the device to our softwares.
2.3.6.2 Driver installation (Linux, MacOS)
We can’t provide drivers or installation instructions for these operating systems. Whether a suitable driver is avail-
able is best found out by searching the Internet. With newer versions of Linux or MacOS, a generic CDC driver
should be “on board”.
2.3.6.3 Alternative drivers
In case the CDC drivers described above are not available on your system, or for some reason do not function
correctly, commercial suppliers can help. Search the Internet for suppliers using the keywords “cdc driver windows“
or “cdc driver linux“ or “cdc driver macos“.

3. Operation and application
3.1 Personal safety
• In order to guarantee safety when using the device, it’s essential that only persons operate
the device who are fully acquainted and trained in the required safety measures to be taken
when working with dangerous electrical voltages
• For models which accept dangerous voltages, a protection against unwanted physical contact
has to be installed on the DC output
3.2 Operating modes
Apowersupplyisinternallycontrolledbydi󰀨erentcontrolorregulationcircuits,whichshallbringvoltageandcurrent
to the adjusted values and hold them constant, if possible. These circuits follow typical laws of control systems
engineering,resultingindi󰀨erentoperatingmodes.Everyoperatingmodehasitsowncharacteristicswhichis
explained below in short form.
• Unloaded operation isn’t considered as a normal operation mode and can thus lead to false
measurements, for example when calibrating the device
• The optimal working point of the device is between 50% and 100% voltage and current
• It’s recommended to not run the device below 10% voltage and current, in order to make
sure technical values like ripple and transient times can be met
3.2.1 Voltage regulation / Constant voltage
Voltage regulation is also called constant voltage operation (CV).
The DC output voltage of a power supply is held constant on the adjusted value, unless the output current reaches
the adjusted current limit. In this case the device will automatically change to constant current operation. Then the
output voltage can’t be held constant anymore and will sink to a value resulting from Ohm’s law.
While the DC output is switched on and constant voltage mode is active, the condition “CV mode active” will be
indicated on the display by the abbreviation CV and also stored as status which can be read via the digital interface.
3.2.1.1 Transient time after load step
For constant voltage mode (CV), the technical date “Settling time after load step” (see 1.8.3)denesatimethat
is required by the internal voltage regulator to settle the output voltage after a load step. Negative load steps, i.e.
high load to lower load, will cause the output voltage to overshoot for a short time until compensated by the voltage
regulator. The same occurs with a positive load step, i.e. low load to high load. There the output collapses for a
moment. The amplitude of the overshoot resp. collapse depends on the device model, the currently adjusted output
voltageandthecapacityontheDCoutputandcanthusnotbestatedwithaspecicvalue.
Depictions:
Example for neg. load step: the DC output will rise
above the adjusted value for a short time. t = transient
time to settle the output voltage.
Example for pos. load step: the DC output will collapse
below the adjusted value for a short time. t = transient
time to settle the output voltage.

3.2.2 Current regulation / constant current / current limitation
Current regulation is also known as current limiting or constant current mode (CC).
The DC output current is held constant by the power supply, once the output current to the load reaches the adjusted
limit.ThenthepowersupplyautomaticallyswitchesThecurrentowingfromthepowersupplyisdeterminedby
the output voltage and the load’s true resistance. As long as the output current is lower than the adjusted current
limit, the device will be in constant voltage mode. If, however, the actual current reaches the set value of current
the device will switch automatically to current limiting.
While the DC output is switched on and constant current mode is active, then the condition “CC mode active” will be
indicated on the display by the abbreviation CC and also stored as status which can be read via the digital interface.
3.2.3 Power limitation
Devices of this series don’t feature a power regulation, only a power limitation. In order to prevent the device from
supplying more than the rated power, the set values of voltage and current limit each other.
It means, when adjusting the current or voltage manually or also in digital remote control, the opposite set value
is always adjusted automatically according to formulas USET = PMAX / IADJ and ISET = PMAX / UADJ. Thus, for example,
both set values can’t be set to 100% at the same time.

3.3 Alarm conditions
This section only gives an overview about device alarms. What to do in case your device indi-
cates an alarm condition is described in section «3.6. Alarms and monitoring».
As a basic principle, all alarm conditions are signaled optically (text in the display), as well as status readable via
the digital interface.
3.3.1 Overtemperature
An overtemperature alarm (OT) can occur from an excess temperature inside the device and causes it to stop
supplying power temporarily. This can occur due to a defect of the internal fan regulation (320 W models only) or
due to excessive ambient temperature.
After cooling down, the device will automatically continue to work, while the previous condition of the DC output
remains and the alarm doesn’t require to be acknowledged.
3.3.2 Overvoltage
Anovervoltagealarm(OVP)willswitcho󰀨theDCoutputandcanoccurif
• the power supply itself, as a voltage source, generates an output voltage higher than set for the overvoltage
alarm threshold (OVP, 0...110% UNom) or the connected load somehow returns voltage higher than set for the
overvoltage alarm limit.
• the OV threshold has been adjusted too close above the output voltage. If the device is in CC mode and if it
then experiences a negative load step, it will make the voltage rise quickly, resulting in an voltage overshoot for
a short moment which can already trigger the OVP.
This function serves to warn the user of the power supply that the device has probably generated an excessive
voltage which could damage the connected load application.
• Thedeviceisn’tttedwithprotectionfromexternalovervoltage
• The changeover from operation mode CC -> CV can generate voltage overshoots
3.3.3 Overcurrent protection
Anovercurrentalarm(OCP)willswitcho󰀨theDCoutputandcanoccurif
• the actual current in the DC output exceeds the adjusted OCP limit.
This function serves to protect the connected load application so that this isn’t overloaded and possibly damaged
due to an excessive current.

3.4 Manual operation
Both displays and the related control elements are identical in the layout and handling. As long
as tracking mode isn’t active, both HMIs are completely separate, even in their HMI settings.
3.4.1 Switching the device on
The device should, as far as possible, always be switched on using the toggle switch on the front of the device.
Afterswitchingon,thedisplaywillrstshowthemanufacturer’slogo,nameand address, followed by device type,
rmwareversion(s),serialnumberanditemnumber.Thelatestsetvaluesarerestored.
A PS 2000 B device doesn’t restore the DC output condition. It will always come up with DC o.
3.4.2 Switching the device o󰀨
• Cutting the AC supply, no matter if caused by using the power supply or a blackout, doesn’t leave the device
enough time to store the latest values. It’s practically powered down immediately. Thus the device stores the set
values and all settings automatically when they are altered, but only in intervals of 10 seconds. It means, if you
would have changed some settings in the menu, you should wait at least 10 seconds after leaving the menu
andbeforeswitchingthedeviceo󰀨.
3.4.3 Conguration via menu
Thesetupmenuservestoconguresomeoperatingparameterswhicharenotchangedfrequently.Thesecanbe
set by pressing button Settings, but only while the DC output is switched o󰀨.
Menu navigation is done using the rotary knobs, their pushbutton
function and the Settingsbutton.Followingisdened:
• Settings button: open menu or leave menu
• Left knob (turn): select a menu item or parameter
• Left knob (push): enter selected menu or leave sub menu
• Right knob (turn): adjust the selected value
• Right knob (push): move cursor
The setup menu has two levels. In order to leave the 2. level to the
1. level and instead of exiting the menu, you can select the item
Menu in the upper left corner and push the knob.
