PSB 10080 -1000 4U xxx

Options and special versions:

WC = Water cooling installed

US208V = Special model for 208 V AC grid

Construction (only stated on type label):

4U = 19" frame with 4 height units

Maximum current of the device in Ampere

Maximum voltage of the device in Volt (“10080” = 80 V)

Series: 10 = Series 10000

Type identication:

PSB = Power Supply Bidirectional

1.6 Intended usage

The equipment is intended to be used only as a variable voltage and current source or only as a variable current sink. Fur-

thermore it’s only intended to be used installed and operated in suitable equipment (19” rack or similar), together with a rigid,

non-retractable AC supply connection.

Typical application for a voltage source is DC power supply to any relevant user, including when used as battery charger to

test charge various battery types, and for current sinks the replacement of an ohmic resistor by an adjustable electronic DC

load in order to load relevant voltage and current sources of any type.

Additionally to the functionality of the equipment as source or sink of electrical energy on the DC side, all models in this series

are also so-called recuperating devices and thus not just drain energy on the AC side, but also source energy when being

sinks on the DC side. This is where the term “bidirectional” comes from. In sink mode the devices become energy recoverers,

but are not dened or considered as energy generation equipment.

• Claims of any sort due to damage caused by non-intended usage will not be accepted

• All damage caused by non-intended usage is solely the responsibility of the operator

1.6.1 Symbols and warnings on the device

Decal Explanation

DANGER

RISK OF ELECTRIC

SHOCK

Disconnect all sources of

supply prior to servicing.

!This warning is primarily related to the reconguration of the device on the DC termi-

nal which, for safety reasons, requires to also cut the device from AC (external main

switch). The same applies to disconnection and reconnection of the AC terminal.

Capacitors on DC, stor-

ing voltage! Discharge

for 10 sec then ground

before working.

DANGER

!Even after disconnection of the DC terminal from an external source there can still be

dangerous voltage potential present between the DC terminal poles and/or between

DC and the enclosure. For safety reasons the DC terminal must be short-circuited

after the capacitors have been discharged and it must also be grounded, i. e. con-

nected to PE.

WARNING

ELECTRICAL

HAZARDS

Authorized personnel

only.

!There can always be a voltage potential on metallic, openly touchable parts on

electrical devices, though the voltage level may not be hazardous. Caution is still

advisable, as these potential can still cause mild electrical shocks or sparking.

WARNING

Read and understand the operat-

ing guide before using this device.

Non-adherence of the instructions

in the operating guide can result

in serious injury or death.

!This is valid for any use of the device.

1.7 Safety

1.7.1 Safety notices

Mortal danger - Hazardous voltage

• Electrical equipment operation means that some parts accessible on the outside of the device can be

under high voltage. Therefore all parts under voltage must be covered during operation! This basically

applies to all models, except for the 10 V and 60 V models according to SELV.

• The DC terminal is isolated from the AC input and not connected to ground internally. Hence there can

be dangerous potential between the DC poles and PE, for instance caused by a connected external

source application. Due to charged capacitors this could even be true if the DC output or the device

are already switched off.

• Do not insert any object, particularly metallic, through the ventilator slots!

• For every reconguration on the AC or DC connectors, specically those which can have a dangerous

voltage potential, the device must be cut completely from the AC supply (main switch on the distant

end of the AC cable); it doesn’t suce to only use the power switch on the front

• Always follow 5 safety rules when working with electric devices:

• Disconnect completely

• Secure against reconnection

• Verify that the system is dead

• Carry out earthing and short-circuiting

• Provide protection from adjacent live parts

• Avoid any use of liquids near the equipment. Protect the device from wet, damp and condensation.

• Do not connect external power sources with reversed polarity to the DC terminal! The equipment will be

damaged, even when completely powered off.

• Never connect external power sources to the DC terminal that can generate a higher voltage than the

rated voltage of the device!

• Never insert a network cable which is connected to Ethernet or its components into the master-slave

sockets on the rear side of the device!

• The equipment must only be used as intended

• The equipment is only approved for use within the connection limits stated on the product label.

• ESD regulations must be applied when plugging interface cards or modules into the relative slot

• Interface cards or modules may only be attached or removed after the device is switched off. It’s not

necessary to open the device.

• Always congure the various protecting features against overcurrent, overvoltage etc. for sensitive loads

to what the target application requires!

• When operating the device as electronic load: always make sure that the energy recovery can feed back

the inverted energy and that it does not switch to isolated operation. For situations of isolated operation

a supervision device (grid protection) has to be installed

• It’s not allowed to run the device on AC sources such as generators or UPS equipment. It must only be

connected to a power grid!

• When controlling the device manually on the HMI while it’s connected to any controlling unit (PLC, PC

etc.) via any analog or digital interface, that controlling unit could take over remote control anytime; for

safety reasons it’s recommended to block remote control by activating the so-called local mode (also

see

“3.5. Manual operation”

and

“3.5.3. Conguration via the menu”

)

1.7.2 Responsibility of the operator

Operator is any natural or legal person who uses the equipment or delegates the usage to a third party, and is responsible

during its usage for the safety of the user, other personnel or third parties.

The equipment is in industrial operation. Therefore the operators are governed by the legal safety regulations. Alongside the

warning and safety notices in this manual the relevant safety, accident prevention and environmental regulations must also

be applied. In particular the operator has to

• be acquainted with the relevant job safety requirements

• identify other possible dangers arising from the specic usage conditions at the work station via a risk assessment

• introduce the necessary steps in the operating procedures for the local conditions

• regularly control that the operating procedures are current

• update the operating procedures where necessary to reect changes in regulation, standards or operating conditions.

• dene clearly and unambiguously the responsibilities for operation, maintenance and cleaning of the equipment.

• ensure that all employees who use the equipment have read and understood the manual. Furthermore the users are to be

regularly schooled in working with the equipment and the possible dangers.

• provide all personnel who work with the equipment with the designated and recommended safety equipment

Furthermore, the operator is responsible for ensuring that the device is at all times technically t for use.

1.7.3 Requirements to the user

ing, knowledge and experience may use the equipment.

The group of people allowed to operate the equipment is additionally limited to:

Delegated persons: these are persons who have been properly and demonstrably instructed in their tasks and the attendant

dangers.

Qualied persons: these are persons who are able through training, knowledge and experience as well as knowledge of the

specic details to carry out all the required tasks, identify dangers and avoid personal and other risks.

1.7.4 Responsibility of the user

The equipment is in industrial operation. Therefore the operators are governed by the legal safety regulations. Alongside the

warning and safety notices in this manual the relevant safety, accident prevention and environmental regulations must also

be applied. In particular the users of the equipment:

• must be informed of the relevant job safety requirements

• must work to the dened responsibilities for operation, maintenance and cleaning of the equipment

• before starting work must have read and understood the operating manual

1.7.5 Alarm signals

The equipment offers various possibilities for signaling alarm conditions, however, not for danger situations. The signals

may be optical (on the display as text or via LED), acoustic (piezo buzzer) or electronic (pin/status output of an analog inter-

face). All alarms will cause the device to switch off the DC terminal. For details about the different alarms refer to section

“3.4. Alarm conditions”

The meaning of the signals is as follows:

Signal OT

(OverTemperature)

• Overheating of the device

• DC terminal will be switched off

• Non-critical

Signal OVP / SOVP

(OverVoltage)

• Overvoltage shutdown of the DC terminal due to high voltage entering the device or generated by

the device itself due to a defect

• Critical! The device and/or the load could be damaged

Signal OCP

(OverCurrent)

• Shutdown of the DC terminal due to excess of the preset limit

• Non-critical, protects the load or source from excessive current consumption

Signal OPP

(OverPower)

• Shutdown of the DC terminal due to excess of the preset limit

• Non-critical, protects the load or source from excessive power consumption

Signal PF

(Power Fail)

• DC terminal shutdown due to AC undervoltage or defect in the AC section

• Critical on overvoltage! AC section could be damaged

Signal MSP

(Master-Slave Pro-

tection)

• DC terminal shutdown due to communication problems on the master-slave bus

• Non-critical

Signal SF

(Share Bus Fail)

• DC terminal shutdown due to signal distortion on the Share bus

• Non-critical

1.7.6 Functionality test

The operator of the device must decide when to check the device for correct functionality, by whom and how often. The

when could either be before every use or after it has been relocated or recongured or perhaps in a dened interval.

Should the set values not be adjustable as instructed below it could simply be due to adjustment limits

interfering. See “3.5.4. Adjustment limits”. When reaching a limit when adjusting value, the device would

indicate in the display.

The test procedure would always be like this:

1. Disconnect all cables (DC, Sense, Share bus, analog interface, USB), except for AC

2. Connect a suitable voltage meter to the DC terminal

3. Switch the device on, adjust a voltage of 10% UNom while the current and power set values all should be at maximum,

switch the DC output on and measure the voltage with the multimeter and compare. Also check what the actual volt-

age on the display shows.

4. Repeat the same thing at 100% UNom.

5. Switch the DC output off and bridge the DC terminal with a cable or copper rails of suitable current capability of at least

INom. If available, put a current measuring device (transducer, current probe).

6. Adjust the current for source mode to 10% INom, switch the DC output on and measure the current with the external

measuring device,if available and compare the measured current to the actual and set value of current on the display

or at least compare the actual current on display with the set value.

7. Repeat the same thing at 100% INom.

Only if the current and voltage are supplied by the device as adjustable in the range of 0-100% FS, the device can be consid-

ered as correctly operational.
