Intelligent Bipolar Power Supply PBZ Series
Intelligent power supply providing arbitrary waveform generation and accurate power simulation!
The PBZ is a series of bipolar DC programmable power supplies that can smoothly pass through zero to provide ± voltage and ± current without changing the output terminals. The PBZ is capable of 4-quad-rant operation, meaning that it is capable of both sourcing and sinking power, ideal for driving both inductive and capacitive loads.This power supply comes equipped with a built-in function generator, allowing for easy waveform and sequence generation. The output cur-rent of the PBZ can be expanded among multiple units by using the synchronization feature. The switching + linear design of the PBZ has allowed for a 40% reduction in weight (approx. 22kg) while achieving extremely high-speed operation (CV mode: 100kHz) and low ripple noise.
Features
Short movie introducing product application
Here are some examples of waveform simulation applications in the PBZ series. Please take a look.
Waveform Generation
Built-in function generator for customizable waveform generation!
In addition to basic sine, square and triangular waveforms, the PBZ allows the operator to customize up to 16 user-defined waveforms with the internal function generator. Amplitude, frequency, start phase, frequency sweep and square wave duty can be programmed as needed. 16 user-defined waveforms can be freely edited and registered to the PBZ internal memory. The sequence feature (see P6) allows for each step in an individual waveform to be customized in detail for a maximum of 1024 steps among 16 programs. *Waveform editing requires proprietery software (Wavy for PBZ).
Sequence function
Sequence customization for convenient waveform generation!
The basic sine, triangular and square waveforms (as well as the 16 user-defined waveforms) can be programmed per sequence step, allowing for easy creation of complex sequences. Sequences are composed of up to 1024 steps, which can be allocated among a maximum of 16 programs. The script function allows for multiple programs to be c ombined and executed as needed.As shown on the right, Program 1 uses 8 steps, allow-ing for 1016 steps to be allocated among the remaining 15 programs. (1024 – 8 = 1016 steps)The script function allows the operator to specify the sequence and number of repitions for set programs. A maximum of 50 rows can be assigned to 1 script for both CV and CC mode.
Step and Program Settings
Example of Script
Synchronized Operation
Seamless sequence execution with no deviation between synchronized units!
This feature allows the user to synchronize the output of multiple PBZ units when executing a sequence, preventing any deviations from occuring even during a long sequence. *Excluding start up delay of up to 1 μs
Multichannel voltage variation test example
Power for automotive vehicles is supplied by the battery, but the power is activated by multiple internal electronic components (+B→ACC→IG) turning ON/OFF in a specific order. There are an extremely large number of electronic components that can cause instability within the automobile, including engine start-up and electrical circuit chat-tering. Therefore, problems caused by this instability such as power interruptions and fluctuations can be planned for and avoided by performing rigorous voltage variation tests on all channels for automotive electronic components.
Car navigation system
- CH1: +B LINE
Power continuously supplied by the battery is distributed to components such as clocks and memory devices. - CH2: ACC LINE
The power supply for car navigation systems are turned ON via the ignition switch’s ACC contact. After the switch is acti-vated, real-time navigation, radio, etc. become possible. - CH3: ILL LINE
+Backup power supply line (ILL) that directly pulls up +B, IG, and ACC.
Parallel Operation
Easily increase capacity!
This feature allows the user to increase the output current by connecting multiple units in parallel. This setup can easily be completed with 2 identical models and the optional parallel operation kit. For systems that require more than 3 units, please refer to the PBZ-SR Series.
For systems that require more than 6 units, please contact your local Kikusui distributor. (Standard models)

Unipolar mode
Full operation in quadrant 2
The unipolar function is unique to the PBZ. “Unipolar mode” allows the PBZ to apply current in both directions (source and sink) while current flows in a single direction. As seen in the diagram below, this feature allows the user full operation in the 1st and 2nd quadrants. Unipolar mode allows the user to bypass power restrictions (PBZ20-20: 100W, PBZ40-10: 180W) present in the 2nd and 4th quadrants when in bipolar mode.
High-Speed Response / Low Ripple Noise
High-Speed Response: 100kHz*1/150kHz*2 (CV mode)
100 kHz/150 kHz frequency specifications (CV). The excellent waveform quality combined with the ultra-fast rise/fall time of 3.5 μs allow the PBZ to reproduce a wide variety of waveforms of the highest quality.
*1 100 kHz for standard models (PBZ20-20, 40-10, 60-6.7, 80-5)
*2 150kHz for “A” models (PBZ20-20A)
Low Ripple Noise: Excellent waveform quality
The excellent waveform quality of the PBZ minimizes noise effects on simulations and pulse-driven devices.
* 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
Four quadrant operation
4-quadrant operation allows for both the sourcing and sinking of power, ideal for driving both inductive and capacitive loads. Also, the PBZ SR/BP is equipped with LAN, USB, GPIB and RS232C standard digital interfaces.
40% lighter than previous models
The switching + linear design of the PBZ has allowed for a 40% reduction in weight (approx. 22kg) resulting in the improved accessibility and portability of bench-top test systems.
Expanded measurement
Built-in measurement features allow for easy testing without the need for multimeters and other measurement devices. Furthermore, the measurement time TRIG signal allows the operator to program measurement start time and measurement delay time.

Protections (overvoltage, overcurrent, V-I LIMIT, overheating)
Overvoltage and overcurrent protection
This protection activates when the output voltage/current exceeds theprotective trip points. The protective trip points can be set seperately in both positive (+) and negative (-) polarities. The following three options can be selected when a protection is activated.
- OUTPUT-OFF: Output is turned OFF.
- POWER-OFF: Output and POWER switch are turned OFF.
- V/I-LIMIT
Prevents voltage and current exceeding the protection trip points. (Output is not turned OFF.)
The V-I/LIMIT function allows the unit to automatically switch from CV mode to I-LIMIT and from CC mode to V-LIMIT. This also allows the unit to automatically switch from CV mode to CC mode, and from CC mode to CV mode.
Overheat protection
This protection is activated when the PBZ temperature reaches abnormally high levels. This protection protects the product from test environments that exceed the ambient temperature, or when sufficient ventilation has not been provided for the intake and exhaust ports.
Soft start and soft stop function
The soft start feature allows the user to gradually increase the output to a given value when turned ON. With soft stop, the user can gradually decrease the output from a given value to 0 when turned OFF. Soft start and stop times can only be set for DC settings. If the OUTPUT key is pressed while soft start or soft stop is in progress, the operation will be cancelled and output turned OFF.
Fine settings function
Fine adjustments (increase, decrease) can be made to the DC setting value.

Remote sensing function
Remote sensing function stabilizes the load terminal output voltage by compensating for voltage drops caused by resistance in the load wires. This function can be used in CV mode with one-way compensation of up to approx. 0.5 V. Please make sure to select load wires with sufficient current capacity so that load wire voltage drop does not exceed the voltage compensation.

External signal input (external voltage control)
The PBZ series is compatible with two types of input signals.
- The DC signal from the internal signal source can be controlled via external voltage at the rear panel (J1 connector) from DC control signal 0 to approx. ±10 V.
- Front panel EXT SIG IN (BNC terminal) input signal.
Composed of a bipolar amplifier using EXT SIG IN (BNC terminal) as the input signal. The amplif ier gain, polar it y (inver ted, non – inver ted) and offset can be set with a maximum input voltage of ±12 Vpeak, maximum input impedance of 10 kΩ, and a common terminal connected to OUTPUT terminal COM.
External signal input (external resistance control)
DC signal of the internal signal source can be controlled using an external variable resistor to change the standard voltage and voltage ratio. With CV and CC mode, the operator can control both voltage and current, respectively. The output is the sum of the external resistor setting, DC panel setting, and remote controller setting.
Temperature-sensitive fan motor
Internal temperature is detected and maintained with an internal fan cooling system.
Interface
USB, GPIB and RS232C standard digital interface. For LAN (option), See here.
PBZ20-20A: Peak Current Output (6x Rating)
Inrush current output up to 6 times the rating! (CV mode)
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.
Recommended Peak Current Duration and Range (Protection)
We recommend a maximum peak current output of up to 6 times the rating (5 times depending on output voltage) within a duration of 10ms (blue area on left). A minimum interval of at least 1 second is required between peak currents, as shorter intervals can cause hardware malfunction. The figure on the left shows the peak and rms current limits when the output is shorted.
- In the peak limit area, peak current is capped at 105% of 6x the rating and can be retained for at least 10 ms.
- There are cases where normal waveforms cannot be generated within the peak limit area. Current limits will still be active ensuring the safety of the operator.
- In the rms limit area, the peak current is limited by the rms value. The current will decrease down to the rated current according to the duration settings.
- When sinking power in quadrant 2 and 4, power will be limited after 10 ms and the regular current limit will be activated.

Simulating Series Output with PBZ series Bipolar Power SuppliesIn this article I will discuss applications for the PBZ series bipolar power supply. One question I get asked a lot about the PBZ series is whether multiple units can be linked in series. The engineer in me is ashamed to have to tell my clients, "unfortunately, no". However, while referred to as "power supplies", the PBZ series are effectively a range of power amplifiers. I tried to come up with an elegant solution for boosting their power output. (Readers who are familiar with audio equipment might be able to tell where I’m going with this.)- Understanding DC Power Supplies (1)This feature offers some tips and tricks on using DC power supplies within the scope of ensuring safe use, although they are not mentioned in the Operation Manuals.
