Description
Kikusui PXB20K-50 Regenerative Bi-Directional 20kW DC Power Supply 0V – 50V 0A – +/- 800A
The PXB series of bidirectional high-capacity DC power supplies condenses a 20 kW large-capacity output into a 3U-size chassis. Not only handling high voltages of 1500V, 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, andmanufacturing! A new generation of bidirectional DC power supplies that support the progression of advanced technologies.
Output Power Range
Mains-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
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
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
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
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.
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.
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.
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
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.
