  • Page 22: Installation & Commissioning

    Preparation Mains connection for a PS 9000 1U series device is done via the included 2 meters long 3 pole mains cord. In case a different AC wiring is required, make sure that the other cable has a minimum cross section of 1.5 mm² (AWG 12).

  • Page 23: Installing The Device

    PS 9000 1U Series 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 sufficient space behind the equipment, minimum 30 cm (12”), for ventilation! • The device isn’t stackable!

  • Page 24: Connection To Dc Loads

    PS 9000 1U Series 2.3.5 Connection to DC loads In the case of a device with a high nominal current and hence a thick and heavy DC connection cable it is necessary to take account of the weight of the cable and the strain imposed on the DC connection.

  • Page 25: Grounding Of The Dc Output

    PS 9000 1U Series 2.3.6 Grounding of the DC output Grounding one of the DC output poles is allowed. Doing so can result in a potential shift of the grounded pole against PE. Because of insulation, there is a max. allowed potential shift of the DC output poles, which also depends on the device model.

  • Page 26: Connecting The "Share" Bus

    PS 9000 1U Series 2.3.8 Connecting the “Share” bus The “Share” connector on the back side is intended to balance the current of multiple units in parallel operation, especially when using the integrated function generator of the master unit.

    3.2.3.1 Power derating The power supplies of series PS 9000 1U offer an extended AC supply voltage range, but are dedicated for the use at typical 230 V , ±10%. Below a certain supply voltage, all models will automatically start to derate, i.e. re- duce the maximum available output power.

  • Page 30: Alarm Conditions

    PS 9000 1U Series 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 + message in the display), acoustically (if activated) and as a readable status via the digital interface.

  • Page 31: Manual Operation

    PS 9000 1U Series Manual operation 3.4.1 Switching on the device The device should, as far as possible, always be switched on using the rotary switch on the front of the device. Alternatively this can take place using an external cutout (contactor, circuit breaker) of suitable current capacity.

  • Page 35: Adjustment Limits

    PS 9000 1U Series 3.4.4 Adjustment limits By default, all set values (U, I, P) are freely adjustable from 0 to 102% of the rated value. This may be obstructive in some cases, especially for protection of applications against overcurrent. Therefore upper and lower limits for current and voltage can be set which limit the range of the adjustable set values.

  • Page 36: Display Modes For Actual And Set Values

    Display modes for actual and set values In general, the display of a PS 9000 1U device shows the actual output voltage and the related set value in the left half of the display and the actual output current and related set value in the right half. In order to have the power set value in direct access, the display mode can be switched.

  • Page 37: The Quick Menu

    PS 9000 1U Series 3.4.7 The quick menu The quick menu is an alternative menu for quick access to offline features while the DC output is online. It is accessible with the button and looks like this: Navigation in the menu is also done with arrow buttons You can select the between view mode and the HMI lock, each with three button pushes.

  • Page 38: Remote Control

    PS 9000 1U Series Remote control 3.5.1 General Remote control is principally possible via any of the built-in interface ports USB, Ethernet/LAN or analog. Important here is that only the analog or any digital interface can be in control. It means that if, for example, an attempt were to be made to switch to remote control via the digital interface whilst analog remote control is active (pin REMOTE = LOW) the device would report an error at the digital interface.

  • Page 39: Remote Control Via The Analog Interface (Ai)

    PS 9000 1U Series 3.5.4 Remote control via the analog interface (AI) 3.5.4.1 General The built-in, galvanically isolated, 15-pole analog interface (short: AI) is located on the rear side of the device and offers the following functions: • Remote control of current, voltage and power • Remote status monitoring (CV, DC output status)

  • Page 45: Loading And Saving An User Profile

    PS 9000 1U Series Loading and saving an user profile The menu “Profiles” serves to select between a default profile and up to 5 user profiles. A profile is a collection of all settings and set values. Upon delivery, or after a reset, all 6 profiles have the same settings and all set values are 0.

  • Page 46: Other Applications

    PS 9000 1U Series Other applications 3.9.1 Parallel operation in Share Bus mode Multiple devices of same kind and model can be connected in parallel in order to create a system with higher total current and hence higher power. To achieve that, the units have to be connected with their DC outputs and their Share Bus.

  • Page 47: Series Connection

    PS 9000 1U Series 3.9.1.5 Alarms and other problem situations Parallel operation, due to the connection of multiple units and their interaction, can cause additional problem sit- uations which do not occur when operating individual units. For such occurrences the following regulations have been defined: • If one or more slave units are switched off on the AC side (power switch, supply undervoltage) and come back...

  • Page 48: Two Quadrants Operation (2Qo)

    This mode of operation refers to the use of a source, in this case a power supply of series PS 9000 1U, and a sink, in this case an electronic load of a compat- ible series (see „1.9.5. Share Bus-Connection“). The source and the sink work alternatively in order to test a device such as a battery, by deliberately charging and discharging it as part of a functional or final test.
  • Page 49 PS 9000 1U Series 3.9.4.3 Settings on the devices The master-slave settings in the MENU of the load device(s) also affect the Share bus. For correct 2QO operation, all involved load units must be slaves on the Share bus. This is achieved by setting the master-slave mode to OFF or SLAVE, depending on if there is digital master-slave in use or not.
  • Page 50 PS 9000 1U Series Service & maintenance Maintenance / cleaning The device needs no maintenance. Cleaning may be needed for the internal fans, the frequency of cleanse is depending on the ambient conditions. The fans serve to cool the components which are heated by the inherent power loss.
  • Page 51 4.3.1 Preface The devices of series PS 9000 1U feature a function to readjust the most important output values when doing a calibration and in case these values have moved out of tolerance. The readjustment is limited to compensate small differences of up to 1% or 2% of the max. value. There are several reasons which could make it necessary...
  • Page 52 PS 9000 1U Series 4.3.3.1 Calibrating the set values ► How to calibrate the DC output voltage Connect a multimeter to the DC output. Connect a load and set it to approx. 5% of the nominal current of the power supply as load current, in this example let’s use 4 A.
  • Page 53 PS 9000 1U Series 4.3.3.3 Calibrating the actual values Actual values of output voltage (with and without remote sensing) and output current are calibrated almost the same way as the set values, but here you don’t need to enter anything, just confirm the displayed values. Please proceed the above steps and instead of Output value select Actual value in the sub menus.
