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 a 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.
• 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.
