  • Page 28: Connection To Ac Supply

    PSB 9000 2.5 kW Series 2.3.4 Connection to AC supply • Connection to an AC supply must only be carried out by qualified personnel and the device must always be run directly on a power grid (transformer are permitted) and not on generators or UPS equipment! • Cable cross section must be suitable for the maximum input current of the device! See tables below.
  • Page 29 PSB 9000 2.5 kW Series 2.3.4.3 Strain relief and plug fixture There is a standard fixture mounted to the AC input con- nection block on the rear. It’s used to prevent the AC plug from loosening and disconnecting due to vibrations or similar. The fixture is also used as strain relief. Using the 4x M3 acorn nuts, it’s recommend to mount the fixture to the AC filter block every time the AC plug has been plugged again.
  • Page 30 Protecting the electrical installation when using energy recovering devices A PSB 9000 device recovers energy and feeds it back into the local power grid. The generated current adds to the grid current (see schematic below) and this can lead to an overload of the existing installation. Considering any two outlets, no matter of what kind they are, there is usually no extra fusing installed.

  • Page 31: Connection To Dc Loads Or Dc Sources

    PSB 9000 2.5 kW Series 2.3.5 Connection to DC loads or DC sources • In the case of a device with a high nominal current and hence a thick and heavy DC connec- tion cable it’s necessary to take account of the weight of the cable and the strain imposed on the DC connection.

  • Page 36: Current Regulation / Constant Current / Current Limiting

    PSB 9000 2.5 kW Series The same occurs with a positive load step, i.e. low load to high load. There the output collapses for a moment. The amplitude of the overshoot or collapse depends on the device model, the currently adjusted output voltage and the capacity on the DC terminal and can thus not be stated with a specific value.

  • Page 37: Internal Resistance Regulation (Source Mode)

    The voltage on the DC input is equal to or lower than the voltage set value The PSB 9000 would not draw any current and enter CV mode. In a situation where the supplied input voltage is approx. equal to or oscillating around the voltage set value, the sink mode would permanently toggle between CV and CR.

  • Page 38: Sink-Source Mode Switching

    PSB 9000 2.5 kW Series 3.3.6 Sink-source mode switching The switchover between sink and source mode happens automatically and only depends on the device’s voltage setting and actual value on the DC terminal or the remote sense connector, if in use.

  • Page 39: Alarm Conditions

    PSB 9000 2.5 kW 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 „3.7. Alarms and monitoring“. As a basic principle, all alarm conditions are signaled optically (text + message in the display) and acoustically (if activated), as well as status via digital interface.

  • Page 40: Safety Ovp

    PSB 9000 2.5 kW Series 3.4.6 Safety OVP This extra feature is only built into the 60 V model of this series.

  • Page 47: Adjustment Limits

    Changing the operating mode In general, the manual operation of a PSB 9000 distinguishes between two or three operating modes, U/I and U/P and U/R, which are tied to set value input using the rotary knobs or ten-key pad. This assignment must be changed if one of the three or four set values is to be adjusted which is currently not assigned to any of the knobs.

  • Page 48: Manual Adjustment Of Set Values

    PSB 9000 2.5 kW Series 3.5.6 Manual adjustment of set values The set values for voltage, current and power are the fundamental operating possibilities of a power supply and hence the two rotary knobs on the front of the device are always assigned to two of the values in manual operation.

  • Page 49: Switching The Dc Terminal On Or Off

    PSB 9000 2.5 kW Series 3.5.7 Switching the DC terminal on or off The DC terminal of the device can be manually or remotely switched on and off.

  • Page 57: Alarms And Monitoring

    PSB 9000 2.5 kW Series Alarms and monitoring 3.7.1 Definition of terms There is a clear distinction between device alarms (see „3.4. Alarm conditions“) such as overvoltage protection or overheating protection, and user defined events such as OVD (overvoltage detection). Whilst device alarms serve to protect the device or the connected load or external source by initially switching off the DC terminal, user defined events can switch off the DC terminal (Action = ALARM), but can also simply give an acoustic signal to make the user aware. The actions driven by user defined events can be selected: Action...

    PSB 9000 2.5 kW Series 3.11 The function generator 3.11.1 Introduction The built-in function generator (short: FG) is able to create various signal forms and apply these to the set value of either voltage or current. The standard functions are based on an arbitrary generator and directly accessible and configurable using man- ual control.

  • Page 62: Method Of Operation

    PSB 9000 2.5 kW Series 3.11.2.3 Resolution Amplitudes generated by the arbitrary generator have an effective resolution of approx. 52428 steps. If the am- plitude is very low and the time long, the device would generate less steps and set multiple identical values after another, generating a staircase effect. It’s furthermore not possible to generate every possible combination of time and a varying amplitude (slope). 3.11.2.4 Possible technical complications Operation of switching mode power supplies as a voltage source can, when applying a function to the output volt- age, lead to damage of the output capacitors due to continuous charging/discharging which causes overheating.

  • Page 80 PSB 9000 2.5 kW Series Step 4: Global limits This configuration screen allows to limit voltage and power globally for the simulation. The current, in this table based simulation, is taken from the calculated PV table which also is an IU table. The output voltage of the power supply is already defined by setting up U in step 2, so it’s recommended to adjust value U to same or higher, else the PV curve may not be working as expected.
