Excellent size and versatility.
This high-capacity DC power supply
is an optimal solution.
The PXT Series of high-performance, high-capacity, wide-range DC power supplies offers amaximum rated output of 20 kW in a compact
3U size. In addition to variable internal resistance, bleeder ON/OFF, and output ON/OFF
delay functions, the PXT series has various
communication interfaces (LAN, USB, andRS232C as standard). It can be used as a standalone device or integrated into testing equipment. Furthermore, the excellent heat dissipation design guarantees an ambient operating
temperature of 50°C, making the unit suitablefor harsh, high-temperature testing environments. The PXT Series is also highly scalable,
and its capacity can be increased to 200 kW inparallel operation (up to 10 units).

PAT250-160TM
PAT350-114TM● Bleeder ON/OFF Function
Turning the bleeder function on quickly discharges the electrical charge accumulated in the load when the OUTPUT was turned off and allows the output
voltage to be lowered. A battery connected to the output terminal will be discharged when the bleeder function is on, even if the OUTPUT is turned off. In
such cases, unnecessary discharge can be prevented by turning the bleeder
function off.

*The time required for the output voltage
to return within ± (0.1 % + 10 mV) of the
rated output voltage when the CV mode response is set to FAST. The output current
fluctuation value is 50 % to 100 % of the
maximum current at the set output voltage.

Required response speed of power supply equipment varies depending on
test conditions and load specifications. The PXT series can change the response speed of the power supply as desired to suit the application.

Item

Description

EnableTurns the bleeder function on. Sink current flows when the output is off.

DisableDisables the bleeder function. Prevents unintended discharge when output isturned off. However, a low sink current will still flow due to the resistance inside
the PXT series.
The reference values of the internal resistance are as follows:
PXT20K-500: approx. 55 kΩ
PXT20K-1500: approx. 560 kΩ

● 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.

● 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.

Performance / Functions● Equipped with Standard LAN Interface and VMCB Function
The PXT series is equipped with LAN, USB, and RS232C interfaces as standard features.
By using the feature of virtual multi-channel bus (VMCB), it allows you to control remotely andmonitoring for 1-to-N as well as N-to-M for large-scale networks. This feature can also be used
to save communication ports or to synchronize the control timing of multiple PXT series units (upto 8 units). The PXB series manufactured by our company can also be mixed and matched for
multi-channel connection.
When connecting the VMCB master unit via LAN

Communication monitoring function
This function monitors the communication status.
For example, the alarm will be activated and the output will be turned off when the
LAN cable is disconnected and the communication is not being confirmed within
the specified time of setting. This function protects the operation from the uncontrolled condition, and it improves the system reliability.
