    PSI 9000 DT Series 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! This basically applies to all models, though 40 V models according to SELV can not generate hazardous DC voltage.

  • Page 8: Responsibility Of The User

    PSI 9000 DT Series 1.7.2 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.

    PSI 9000 DT Series 3.2.2 Current regulation / constant current / current limiting Current regulation is also known as current limiting or constant current mode (short: CC). The DC output current is held constant by the power supply as soon as the output current to the load reaches the adjusted limit.

  • Page 41: Alarm Conditions

    PSI 9000 DT 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 signalled optically (text + message in the display), acoustically (if activated) and as a readable status via the analog and digital interfaces.

  • Page 48: Manual Adjustment Of Set Values

    PSI 9000 DT Series 3.4.6 Manual adjustment of set values The set values for voltage, current and power are the fundamental operating possibilities of a power supply and hence, in manual operation, the two rotary knobs on the front of the device are always assigned to two of these values.

  • Page 52: Remote Control

    PSI 9000 DT Series Remote control 3.5.1 General Remote control is possible via the built-in analog interface, USB port or Ethernet port. Important here is that ei- ther the analog or any of the digital interfaces 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 via the digital interface.

  • Page 53: Remote Control Via The Analog Interface (Ai)

    PSI 9000 DT Series 3.5.4 Remote control via the analog interface (AI) 3.5.4.1 General The built-in and galvanically isolated 15-pole analog interface (short: AI) on the rear side of the device offers the following possibilities: • Remote control of current, voltage, power and internal resistance • Remote status monitoring (CV, DC status)
  • Page 54 PSI 9000 DT Series 3.5.4.3 Acknowledging device alarms In case of a device alarm occurring during remote control via analog interface, the DC output will be switched off the same way as in manual control.

  • Page 57: Alarms And Monitoring

    PSI 9000 DT Series Alarms and monitoring 3.6.1 Definition of terms There is a clear distinction between device alarms (see „3.3. Alarm conditions“), caused by the overvoltage protec- tion or overheating protection, and user defined events such as OVD (overvoltage detection). Whilst device alarms serve to protect the device and the connected load by instantly switching off the DC output, user defined events can either switch off the DC output (Action = ALARM) or simply give an acoustic signal to make the user aware.

  • Page 66: Arbitrary Function

    PSI 9000 DT Series 3.10.10 Arbitrary function The arbitrary (freely definable) function offers the user further scope. There are 99 sequence points available to run on either current I or voltage U, which all have the same parameters, but can be differently configured so that standard functions (triangle, rectangle etc.) can be generated or complex curves can be “constructed”.
  • Page 67 PSI 9000 DT Series Schematic diagram: Applications and results: Example 2 Focussing 1 cycle of 1 sequence point: The DC values of start and end are the same but the AC (amplitude) isn’t. The end value is higher than the start value so the amplitude increases continuously with each new half sine wave through the sequence point.
  • Page 68 PSI 9000 DT Series By linking together a number of differently configured sequence points, complex progressions can be created. Smart configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave functions and thus, e. g. a curve of rectangular waves with differing amplitudes or duty cycles could be produced.
  • Page 69 PSI 9000 DT Series 3.10.10.1 Loading and saving the arbitrary function The 99 sequence points of the arbitrary function, which can be manually configured with the control panel of the device and which are applicable either to voltage (U) or current (I), can be saved to or loaded from a common USB stick via the front side USB port.
