PS 2000 B Single Series
1.9 Construction and function
1.9.1 General description
The laboratory power supplies of the series PS 2000B are very compact and rugged devices and incorporate
interesting features within small dimensions. The contactless design makes them ideally suited for operation in
schools, educational facilities, workshops or laboratories.
Theserieso󰀨ersthreepowerclassesof100W,160Wand320W.
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.
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
1 x Power supply device
1 x USB stick with documentation and software
1 x Mains cord
1.9.3 Optional accessories
For these devices the following accessories are available:
Multi Control license
Ordering numbers
Single license: 33 100 229
5 pack of licenses: 33 100 230
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.
1.9.4 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display, two rotary knobs and two pushbuttons.
1.9.4.1 Display
Thegraphicdisplayisdividedintothreeareas.Innormaloperationtheupperpart(⅔)isusedtoshowactualand
setvaluesandthelowerpart(⅓)todisplaystatusinformation:
Actual voltage + set value
Regulation mode CV
OVP threshold
Actual current + set value
Regulation mode CC
OCP threshold
Various status displays (symbols, strings)
• Actual / set values area (blue / red)
In normal operation the DC output values (large numbers) and set values (small numbers) for voltage and current.
While the DC output is switched on, the actual regulation mode CV or CC is displayed above to the corresponding
setvalue,asshowninthegureabovewithexampleCC.
The set values can be adjusted by rotating the knobs below the display, whereas pushing the knobs is used to select
a particular digit. Logically, the values are increased by clockwise turning and decreased by anti-clockwise turning.
