Kikusui PBZ Series Intelligent Bi-Polar Power Supply, Up to 40V

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.

• Synchronized operation– When using multiple units, the PBZ can synchronize the output of each individual power supply. The types of synchronization operations used are trigger synchronization, clock synchronization, and combined trigger and clock synchronization. (Up to 5 units can be connected)
• Master-slave parallel operation– The output current is expandable through master-slave parallel operation with up to 2 of the same model connected using a standard option kit. Also, 3 to 5 units can be configured in parallel upon request.
• Waveform generator, Sequence functions– The PBZ creates waveforms with ease. 16 different types of arbitrary waveforms are available as well as the sine wave, square wave, and triangle wave. Various patterns can be simulated with up to 1024 steps within a single sequence.
• Low ripple and noise (in CV mode)– For the Ripple 2mVrms, Noise 20mVp-p (PBZ20-20)
• Selectable Bi-polar/Uni-polar mode– The maximum sink power is limited to 100W for model PBZ20-20 (180W for model PBZ40-10) in bi-polar mode; however, uni-polar mode has no limitation in the operating area, so the PBZ can operate at the full rated power of 400W.
