Output power range 2 to 3 times mains-powered operation

Output power range 2 to 3 times mains-powered operationMains-powered power supply with a wide range of operating ranges and combinations of voltage and current settings. If the voltage of the connected DUT is lower than the voltage setting of the PXB series, current flows from the PXB series to the DUT. If the voltage of the connected DUT is higher than the voltage setting of the PXB series, current flows from the DUT to the PXB series.

Achieves high-speed rise and fall times

Achieves high-speed rise and fall timesAchieves a rise/fall time of 10 ms, which is several tens of times faster than conventional switching power supplies. Enabling high-speed power fluctuation testing that cannot be handled by ordinary DC power supplies.

Highly stable operation with high resistance to capacitive loads

Highly stable operation with high resistance to capacitive loadsDesigned for highly stable operation, without oscillation or overshoot even when a load with a large capacitive component is connected.
Slew rate and response can be varied to match the characteristics of the connected load, suppressing oscillation and overshoot.

Optimized for different purposes and applications, with selectable response speeds

Optimized for different purposes and applications, with selectable response speedsThe required power supply response time varies depending on the test conditions and load specifications. The response speed of the PXB Series power supply can be changed to suit different applications.

Up to 25 units can be operated in parallel, achieving 500 kW *

Up to 25 units can be operated in parallel, achieving 500 kWIncluding master machine, up to 25 units (500 kW) can be operated in parallel. Connection is with one-control parallel operation, and the panel of the master machine can control and display the entire system. With the automatic recognition function, the need for complicated settings is eliminated, allowing the construction of high-capacity systems.
* Parallel operation is possible between models with different input rated voltages. Please contact us if you wish to operate more than 10 units in parallel.

Sequence function

Sequence functionPreset operations can be run continuously. Total of 30 programs, and up to 10,000 steps can be created for all programs. Programs stored in the unit’s memory, and data can be exported to a USB memory stick from the front panel.

Pulse function / Sign function

Pulse function / Sign function“Pulse” operation can be set, which repeatedly executes a binary setting, or “sine” operation, changing the current in a sinusoidal manner.

Regenerative function (on-premises) contributes to carbon neutrality.

Regenerative function (on-premises) contributes to carbon neutrality.When power is regenerated to the main unit from an inverter or battery, the load power is converted to reusable power and regenerated to the AC LINE. This can contribute to reducing the amount of heat exhaust and saving energy.
*Regenerative efficiency 90% or more (at rated load in Typ)

*The PXB series is designed for on-site regenerative power. Use in an environment where the power in the premises is greater than the regenerative power.

Rare interview transcripts from those involved in the development of the bi-directional power supply

The electric drive changes the power from the engine to the motor, which converts energy in both directions, so the electrical components (inverter, battery, etc.) that drive the motor are subject to bi-directional current flow.

In the evaluation of these electrical components, the market demanded a power supply that could handle bidirectional current, and the power band varied from 10 kW to several 100 kW, depending on the type of EV, so there was a wide range of power needs. At that time, Kikusui did not have a bi-directional DC power supply or a power supply that could handle several hundred kW, and we decided to develop a bi-directional DC power supply that could sufficiently meet market demands, considering that market needs would increase further if not only cars but all forms of transportation became electrically powered.
