PBZ Series

Intelligent Bi-Polar Power Supplies (Switching/Series Regulated, CV/CC) : 30 Models



Outline

The PBZ series is a bipolar type DC regulated power source that can continuously change both + and – polarities passing through 0 without changing the output terminal.
By adopting a “Switching + Linear” system, the PBZ is able to realize both drastic weight reduction as well as high speed and low noise operation. Since operation covers 4 quadrants, power can be both supplied (source) and absorbed (sink). The PBZ can also drive inductive or capacitive loads. The unit also equips a signal generator function which enables waveform and sequence creation. The PBZ is also capable of synchronized operation which is required for voltage variation tests, and it can also be expanded for large current applications through master-slave parallel operation.


Features

  • Low ripple and noise (in CV mode)
    For the Ripple 2mVrms, Noise 20mVp-p (PBZ20-20)

    *PBZ40-10 :Ripple 4 mVrms, noise 20 mVp-p
    *PBZ60-6.7 :Ripple 4 mVrms, noise 30 mVp-p
    *PBZ80-5 :Ripple 4 mVrms, noise 30 mVp-p
  • Waveform generation function
    In addition to the basic sine, square and triangular waveforms, the PBZ series is equipped with a user-defined waveform generating function that can register up to 16 waveforms. It allows the amplitude, frequency, start phase, frequency sweep and square wave duty to be set as needed.
    The 16 user-defined waveforms can be freely edited, and the original created and edited waveforms can be registered and easily recalled for use. The sequence function allows each waveform to be set as a single step, and a maximum of 1024 steps can be set in the 16 programs. 
  • Sequence function
    The basic sine, triangular and square waveforms, as well as the 16 user-defined waveforms, can each be set as a sequence step, allowing even complex sequences to be created easily. Sequences are composed of up to 1024 steps.This combination of steps forms a program, and the 1024 steps can be allocated and set in a maximum of 16 programs. When executing sequences, in addition to executing a single program, the script function also allows multiple programs to be combined and executed as needed.
    A script is a function that specifies the sequence and number of repetitions for the set programs. A maximum of 50 lines can be set in 1 script. 1 script can be set each for CV and CC mode.
    As shown in the figure, when Program 1 uses 8 steps, 1024 – 8 = 1016, the remaining 1016 steps can be allocated to the remaining 15 programs.
  • Synchronized operation function
    This function synchronizes the power output when a sequence is executed using multiple PBZ.It prevents time deviations from occurring even when a long sequence is executed.
    * A delay of up to 1μ s occurs at the start.
  • Parallel operation function
    This function expands the output current. It allows multiple units to be connected in parallel according to the required current. With 2 standard units of the same model and the optional parallel operation kit, the user can easily complete the setup.
    Although up to 5 units can be operated in parallel, if 3 or more units will be used, please consult with us.
  • Unipolar mode
    This is a function unique to this product. Because the voltage is unipolar, this function is called “unipolar mode”. With unipolar power, although the current flows in a single direction, in unipolar mode it is still possible to apply current in both directions (source and sink). As shown in the diagram, on a graph with perpendicular axes of voltage (vertical) and current (horizontal), operation is possible in quadrant 1st and 2nd quadrants (2 quadrants). In bipolar mode, there are power restriction areas (PBZ20-20: 100W, PBZ40-10: 180W, PBZ60-6.7/PBZ80-5: 200W) in 2nd and 4th quadrants. However in unipolar mode, operation is possible in the full area of 2 quadrants.
  • Control via browser (”with LAN” model)
    The LAN interface applies to the LXI (LAN eXtensions for Instrumentation)*. If that interface is used, it is possible to control and monitor the power supply from a browser.
    *PBZ60-6.7 and PBZ80-5 are under application.
  • Others
    • CV/CC selectable mode
    • Memory function
    • Protection functions (Over voltage/Over current/Over heat/ Power limit)
    • Fine setting
    • Key lock
    • Remote sensing
    • Output voltage/current monitor
    • External voltage/resistance control
    • External signal input
    • Status signal output

  • Rack system (PBZ SR/BP series)
    The PBZ SR/BP series is a series of high-power bipolar DC stabilized power supplies. The PBZ SR/BP series are designed based on the PBZ Intelligent Bipolar power supply series, that supports large currents (up to ±200 A) and is assembled with exclusive rack system (Smart Rack). The4-quadrant operation allows the power to be supplied (source) or absorbed (sink), and it is suitable for driving inductive loads or capacitive loads. Also, the PBZ SR/BP series are equipped with LAN, USB, GPIB, and RS232C as standard communication interfaces.
