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 fixed 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 define thresholds for an automatic output cut-off 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 beneficial 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
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 first 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 device features two identical control panels, also called HMI (

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 v set value
Regulation mode CV
OVP threshold
Actual c 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 figure above with example
CC
