1.7 Safety
1.7.1 Safety notices
Mortal danger - Hazardous voltage
• Electrical equipment operation means that some parts can be under dangerous voltage.
Therefore all parts under voltage must be covered!
• All work on connections must be carried out under zero voltage (output not connected
to load) and may only be performed by qualied and informed persons. Improper ac-
tions can cause fatal injury as well as serious material damage!
• Never touch cables or connectors directly after unplugging from mains supply as the
danger of electric shock remains!
• Never touch the contacts on DC output terminal directly after switching off the DC
output, because there still can dangerous voltage present, sinking more or less slowly
depending on the load! There also can be dangerous potential between negative DC
output to PE or positive DC output to PE due to charged X capacitors.

1.7.5 Alarm signals
The equipment offers various possibilities for signalling alarm conditions, however, not for danger situations. The
signals may be optical (on the display as text) acoustic (piezo buzzer) or electronic (pin/status output of an analog
interface). All alarms will cause the device to permanently or temporarily switch off the DC output.
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DC output will be switched off temporarily
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC output due to high voltage entering the device or gen-
erated by the device itself due to a defect or because the adjusted OVP threshold was
lower than the actual output voltage
• Critical! The device and/or the load could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive current consumption
Signal OPP
(OverPower)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive power consumption

(1 Related to the nominal values, the accuracy denes the maximum deviation between an adjusted values and the true (actual) value.
Example: a 80 V model has min. 0.1% voltage accuracy, that is 80 mV. When adjusting the voltage to 5 V, the actual value is allowed to differ max. 80 mV, which
means it might be between 4.92 V and 5.08 V.

1.9 Construction and function
1.9.1 General description
The electronic high performance power supplies of the PS 9000 1U series are especially suitable for test systems
and industrial controls due to their compact construction in a 19” enclosure with 2 height units (2U).
For remote control using a PC or PLC the devices are provided as standard with a USB-B slot and an Ethernet
port on the back side as well as a galvanically isolated analog interface. All interfaces are galvanically isolated up
to 1500 V DC.
In addition, the devices offer as standard the possibility for parallel connection in Share bus operation for constant
current sharing. Operating in this way allows up to 10 units to be combined to a single system with a total power
of up to 30 kW.
All models are controlled by microprocessors. These enable an exact and fast measurement and display of actual
values.
1.9.2 Block diagram
The block diagram illustrates the main components inside the device and their relationships.
There are digital, microprocessor controlled components (KE, DR, BE), which can be target of rmware updates.

1.9.4 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display, two rotary knobs with pushbutton function and six
pushbuttons.
1.9.4.1 Display
The graphic display is divided into a number of areas. In normal operation the left upper half is used to show actual
values and the lower half is used to display status information and set values:
Actual values
U/I or U/P
Regulation mode
Alarms
Set value of voltage Status: control location / panel lock Set value of current or
Set value of power
• Actual values area (upper half)
In normal operation the DC output values (large numbers) of voltage and current resp. of power are displayed,
depending on the selected view mode. The display format of values is according to what’s listed in 1.9.4.4.
Furthermore, the actual regulation mode CV, CC or CP (see „3.2. Operating modes“) is displayed here, as well as
alarms with abbreviations (OT, OVP, OCP, PF, OPP). For details refer to „3.3. Alarm conditions“.
• Set values area (lower half, left and right side)
The set values of voltage and current (mode: U/I) resp. of voltage and power (mode: U/P) are displayed here and
are adjustable with the left hand and right hand rotary knobs when operating the device manually. While doing
so, the digit to adjust can be selected by pushing the corresponding rotary knob, in order to move the cursor. The
left hand rotary knob is always assigned to the DC output voltage and related parameters like OVP or U-max,
whereas the right hand rotary knobs is either assigned to the DC output current and related parameters or to the
DC output power. In remote control condition, no matter if analog or digital, the set values given from remote are
displayed here.
Logically, the values are increased by clockwise turning and decreased by anti-clockwise turning, unless they are
somehow limited by a maximum value or an adjustment limit (see „3.4.4. Adjustment limits“).
General display and settings ranges:
Display Unit Range Description
Actual voltage V 0-125% UNom Actual values of DC output voltage
Set value voltage V 0-102% UNom Set value for limiting the DC output voltage
Actual current A 0.2-125% INom Actual value of DC output current
Set value current A 0-102% INom Set value for limiting the DC output current
Actual power W 0-125% PNom Actual value of output power, P = U * I
Set value power W 0-102% PNom Set value for limiting DC output power
Adjustment limits A, V, kW 0-102% Nominal val. U-max, I-min etc., related to the physical units
Protection settings A, V, kW 0-110% Nominal val. OVP, OCP etc., related to the physical units
• Status area (lower half, middle)
This area shows the control location mode (see „3.5.2. Control locations“) or another status (see table below). In
case pushbutton is activated while the output is on, the quick menu (see „3.4.7. The quick menu“) will be
displayed:

1.9.4.2 Rotary knobs
As long as the device is in manual operation, the two rotary knobs are used to adjust set values, as well
as setting the parameters in the settings menu. For a detailed description of the individual functions see
section „3.4 Manual operation“ on page 31.
1.9.4.3 Pushbutton function of the rotary knobs
The rotary knobs also have a pushbutton function which is used in all menu options for value adjustment to move
the cursor by rotation as shown:
1.9.4.4 Resolution of the displayed values
In the display, set values can be adjusted in xed increments. The number of decimal places depends on the
device model. The values have 4 or 5 digits, while actual and set values related to the same physical unit always
have the same number of digits.
Adjustment resolution and number of digits of set values in the display:
Voltage,
OVP, U-min, U-max
Current,
OCP, I-min, I-max

100 A 50.01 A
In manual operation every set value can be set in the increments given above. In this case
the actual output values set by the device will lie within percentage tolerances as shown in the
technical data sheets. These will inuence the actual values.
1.9.5 Share Bus-Connection
