Condenses a 20 kW large-capacity output
into a 3U-size chassis.
Not only handling high voltages of 1500 V, but also capable of both power and regeneration in both directions in a single unit.
We provide a new power supply test environment for electrical and electronic equipment that is becoming increasingly high-powered.
In addition, a variety of analog, digital, and communication interfaces are provided for optimal operation at any stage of research, development, and manufacturing! A new generation of bidirectional DC power supplies that support the progression of advanced technologies.
Output power range
2 to 3 times mains-powered operation
Mains-powered power supply with a wide range of operating ranges and combinations of voltage and current settings.
Source
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.
Sink
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.
Reasons the PXB Series is recommended.
Highly stable operation
with high resistance to capacitive loads
Designed 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.
Achieves high-speed rise and fall times
Achieves 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.
High power density
High-power & compact
Condenses a 20 kW large-capacity output into a 3U-size chassis.
Selectable power input
Full output at rated power regardless of input voltage
Choose from 3-phase 3-wire 200 V or 400 V models. No output limitation for either input voltage.
Reliable and solid performance
even under high temperatures
Solid performance under operating temperatures of 0°C to 50°C. Exhibits full performance even in environments with severe ambient temperatures, such as when installed in equipment. (Excluding some models.) Caution: PXB10K-50, PXB20K-50, PXB20K-100 and PXB20K-250 operates in the temperature range of 0°C to +40°C.
External control function
The EXT CONT connector on the rear panel can be used to control the PXB series with external devices. The general-purpose digital input and output terminals can be assigned any function, facilitating system construction in combination with other measurement devices.
Digital I/O standard for both NPN and PNP type PLCs. Analog I/O is isolated from output terminals as standard, allowing safe analog control from PLC.
Application 1Inverter and motor evaluation test
Application 2Aging tests for bidirectional DC/DC converters
Features
Priority operation mode
Mode of operation can be set, as constant voltage (CV), constant current (CC), or constant power (CP), when output is turned on. Overshoot can be prevented by setting CC mode priority when batteries, power supplies, etc. are connected.
SEAM mode
Equipped with SEAM mode allowing current to flow in both directions without changing voltage values. Suitable for charging and discharging storage batteries. Can suppress current overshoots and undershoots which may often occur during operation mode switching after charge/discharge.
Optimized for different purposes and applications, with selectable response speeds
Required response speed of power supply equipment varies depending on test conditions and load specifications. The PXB series can change the response speed of the power supply as desired to suit the application.
Response
FAST, SLOW
Slew rate
Selectable in 5 steps
Variable internal resistance function
Function can change the output voltage value in constant voltage operation, according to the output current value based on the set resistance value. Simple simulation of Internal resistance of rechargeable batteries and wire harnesses etc.
| Setting range | PXB20K-50 | 0 mΩ to 63 mΩ |
|---|---|---|
| PXB20K-250 | 0 mΩ to 1575 mΩ | |
| PXB20K-500 | 0 mΩ to 5250 mΩ | |
| PXB20K-1000 | 0 mΩ to 21000 mΩ | |
| PXB20K-1500 | 0 mΩ to 63000 mΩ |
Sequence function
Preset 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.
I-V characteristic function
By registering multiple arbitrary points on the I-V characteristics, arbitrary I-V characteristics can be set for each CC and CV operation mode. Arbitrary points can be registered from 3 to 100, making it possible to simulate the I-V characteristics of rechargeable batteries and other devices.
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.
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 of over 90% (at rated load).
*The PXB series is designed for on-site regeneration. Use in an environment where the power on-site is greater than the regenerative power.
Up to 25 units can be operated in parallel, achieving 500 kW *
Including 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.
Equipped with touch panel display
By pressing or swiping a finger on the display, on-screen items can be selected, or numerical values set. The display is pressure-sensitive and can be operated even with gloves.
Panel explanation
Outline drawing are common to all models. *Maximum dimensions include protrusions and accessory covers.
External Control
The EXT CONT connector on the rear panel can be used to control the PXB series with external devices. The general-purpose digital input and output terminals can be assigned any function, facilitating system construction in combination with other measurement devices.
Digital I/O standard for both NPN and PNP type PLCs. Analog I/O is isolated from output terminals as standard, allowing safe analog control from PLC.

*1 Basic insulation *2 Does not apply to specially ordered or modified products. *3 Only for models with CE marking / UKCA marking on their body. *4 This is a Class A instrument. This product is intended for use in an industrial environment. This product may cause interference if used in residential areas. Such use must be avoided unless the user takes special measures to reduce electromagnetic emissions to prevent interference to the reception of radio and television broadcasts. *5 This is a Class I instrument. Be sure to ground this product’s protective conductor terminal. The safety of this product is guaranteed only when the product is properly grounded. *6 Pollution is addition of foreign matter (solid, liquid or gaseous) that may produce a reduction of dielectric strength or surface resistivity. Pollution Degree 2 assumes that only non-conductive pollution will occur except for an occasional temporary conductivity caused by condensation. *7 Only for models with cTUVus marking on their body.
