For the Progressive

X electric applications“”

A better power supply testing environment, for an increasingly electric and electronic world.
Our goal was to create a bidirectional power supply that can flexibly respond to various"X" requirements related to advanced technology!
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 highvoltages of 1500 V, but also capable ofboth power and regeneration in both
directions in a single unit. We provide a
new power supply test environment forelectrical and electronic equipment thatis 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 generationof bidirectional DC power supplies that
support the progression of advanced
technologies.

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.

Performance / Functions● Priority operation mode

● Sequence function

Mode of operation can be set, as constant voltage (CV), constant current (CC), or constant power (CP), when output is turned on. Overshootcan be prevented by setting CC mode priority when batteries, power
supplies, etc. are connected.

Preset operations can be run continuously. Total of 30 programs, andup 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 stickfrom the front panel.
Programs can be linked

Program 1● Pulse function / Sign function

Prog

A total of 30 programs can be created.

"Pulse" operation can be set, which repeatedly executes a binary setting, or "sine" operation, changing the current in a sinusoidal manner.

Up to 10,000 steps can be created for all programs combined.

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 exhaustand saving energy.
*Regenerative efficiency of over 90% (at rated load).
