Regulated DC power supplies are widely used in a great range of applications because of their high efficiency and many advantages.
In this white paper, we are going to define the differences between DC power supplies and batteries by explaining the battery simulation testing applications.

You might have asked yourself some simple questions when selecting a power supply for your project.
This white paper shows the five most common simple questions on DC power supplies that you may want to know. Detailed answers for each question with some useful tips are given in this white paper.

DC motor requires a startup current which is higher than its running current. Not all DC power supplies can provide sufficient power to DC motors.
This white paper shows the capability of bipolar DC power supply PBZ20-20A, which supplies a short-term peak current up to 6 times its rating current.

This white paper helps you to understand the typical issues involved with load conditions and how to solve them, particularly focusing on three types of loads: 1) inductive load 2) capacitive load such as battery and 3) regenerative load one by one.

This white paper explains the best practices for connecting a power cable and load cable to the DC power supply.
This helps you learn about typical wiring problems in an electrical system and how to avoid them.

This white paper describes a good power supply.
We explain how to determine the ability of the power supply by four characteristics associated with the power supply’s specification: line regulation, load regulation, transient response and ripple noise.

When using a DC power supply for charging a load such as battery, the DC power supply absorbs a current from such loads when the output is turned off.
This white paper explains the power supply’s behavior.

For PBZ Series, a magnetic relay is used to turn the output on/off.
This white paper focuses on following topic of the output on/off behavior of PBZ and explain how:
1. the output voltage and output impedance change during the output on/off
2. PBZ responses to the output-on/off external signal input

This white paper shows vibration test method in CV mode for automotive wire harness with connector, and explains how to conduct the test.
The connection, the setting and the operation to achieve the test are described step by step.

When making the master-slave connection such as signal wiring and load connection, you may find some issues with load connection.
This white paper describes not only the basic connection methods, also advanced techniques to stabilize an unstable output.

To charge batteries, it is recommended to connect a diode in series at an output of DC power supply. With a diode, CC can be properly supplied, however CV may be unstable if using remote sensing at battery terminals.
This white paper describes other stable CC-CV charging methods with a switch.

PBZ Series can change the square waveform frequency and duty cycle. Using the sequence function, you can also change the pulse width.
This white paper explains how to change the pulse width with PBZ Series.

To transmit a synchronized trigger pulse for output from PBZ Series, you can create a trigger signal output through the sequence function or with a certain setting.
This white paper describes to realize it.

PBZ Series is a bipolar power supply that can be also operated in quadrant 2 to sink the current. This function enables you to measure an output impedance of DUT by using PBZ Series as an electronic load.
This white paper explains how to flow the load current to DUT power supply.

This white paper provides you with introduction on a method to achieve a double output voltage using two units of PBZ Series.
Connection, Setting and Operation to achieve it are described step by step.

DC power supply can provide dual (positive and negative) output by connecting two power supplies in series.
This white paper shows the procedure how to produce positive/negative output and describes dual tracking function.

When setting the output current or voltage from DC power supply, a higher accuracy can be achieved by panel setting or remote PC setting instead of ammeter adjustment.
This white paper explains the accuracy difference between these two methods.

The same model of Kikusui DC power supply can be connected in parallel. Master-slave parallel operation is not available when connecting the different power supply model.
This white paper describes the recommended parallel operation to increase the output capacity with the different models.
