  • Page 43: Current Regulation / Constant Current / Current Limiting

    PSB 9000 3U Series Depictions: Example for neg. load step: the DC output will rise Example for pos. load step: the DC output will collapse above the adjusted value for a short time. t = transient below the adjusted value for a short time. t = transient time to settle the output voltage.

  • Page 44: Internal Resistance Regulation (Source Mode)

    PSB 9000 3U Series 3.3.4 Internal resistance regulation (source mode) Internal resistance control (abbr. CR) of power supplies is the simulation of a virtual internal resistor which is in series to the voltage source and thus also in series to the load. According to Ohm’s law, this causes a voltage drop, which will result in a difference between adjusted output voltage and actual output voltage.

  • Page 45: Sink-Source Mode Switching

    PSB 9000 3U 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 46: Alarm Conditions

    PSB 9000 3U 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 signalled optically (text + message in the display) and acoustically (if activated), as well as status via digital interface.

  • Page 47: Safety Ovp

    PSB 9000 3U Series 3.4.6 Safety OVP This extra feature is only built into the 60 V models of this series. Similar to the regular overvoltage protection (OVP, see 3.4.3), the Safety OVP is supposed to protect the application or people according to SELV. The alarm shall prevent the device from providing an output voltage higher than 60 V.

  • Page 48: Manual Operation

    PSB 9000 3U Series Manual operation 3.5.1 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.

These can be read using a standard multimeter or similar. d) Switching between source and sink mode You can also switch between both modes when remotely controlling the device with the AI. This is done using the voltage set value (VSEL), which then must not be tied to a fixed potential, like shown in example b).

    PSB 9000 3U Series Schematic diagram: Application and result: This function generates a rising or falling ramp between start and end values over the time t2. Time t1 creates a delay before the ramp starts. The function runs once and stops at the end value. To have a re- peating ramp, function Trapezoid would have to be used instead (see 3.11.8).

    PSB 9000 3U Series 3.11.14 FC table function (fuel cell) 3.11.14.1 Preface The FC table function is used to simulate the characteristics of voltage and current of a fuel cell. This is achieved by setting up some parameters which define points on a typical fuel cell curve, which is then calculated as UI table and passed to the internal function generator.

The calculation is always done between to succeeding points on the day trend curve. The dwell time of every curve point is adjustable between 500 and 1,800,000 milliseconds (see above, format of the day trend data file).

    PSB 9000 3U Series 3.12 Other applications 3.12.1 Parallel operation in master-slave (MS) 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. For parallel operation in master-slave mode the units are usually connected with their DC terminals, their Share bus and their master-slave bus, which is a digital bus that makes the system work as one big unit regarding adjusted values, actual values and status.
  • Page 100 PSB 9000 3U Series A max. of 16 units can be connected via Share bus. 3.12.1.4 Wiring and set-up of the digital master-slave bus The master-slave connectors are built-in and can be connected via network cables (≥CAT3, patch cable). After this, MS can be configured manually or by remote control.

    PSB 9000 3U Series • Loss of connection to any slave will result in shutdown of all DC terminals, as a safety measure, and the master will report this situation in the display with a pop-up “Master-slave security mode”. Then the MS system has to be re-initialised, either with or without re-establishing connection to the disconnected unit(s) before.
