Description


Kikusui PBZ20-20A DC Power Supply

The Kikusui PBZ 20-20A (+/-0 to 20V +/-0 to 20A (6x pk)) is a bipolar high speed 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 now incorporates 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 PBZ is also equipped with a signal generator function which enables waveform and sequence creation. The PBZ is also capable of synchronised operation which is required for voltage variation tests. Multiple PLZ units can be combined for large current applications through master-slave parallel operation.
Peak current output 6 times the rating (PBZ20-20A)
The PBZ20-20A is capable of generating a short-term peak current up to 6 times the rating when current response is set to 1ms in CV mode. Other response settings will activate the current limit and allow the operator to safely use the device without 6x peak current output. When current response is set to 1ms, the PBZ20-20A automatically decreases response speed and allows for peak current ouput while the current limit is deactivated. This means that the current function will be active at all times when short-term peak current is not output and will have no effect on current response in CC mode. Short-term peak current output is available in both bipolar and unipolar mode.

Features:

  • 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)
  • Parallel operation function
  • Unipolar mode (In unipolar mode it is still possible to apply current in both directions (source and sink).
  • Control via browser (”with LAN” model)
  • 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
