1.1 About This Manual
This manual describes the PAT-T Series (4 kW type), regulated DC power supply.
Applicable firmware version of the PAT
p. 2-9 This manual applies to PATs with firmware version 4.0x.
When making an inquiry about the product, please provide us with the following
information.
•Model (indicated at the top section on the front panel)
•Firmware version
•Serial number (indicated at the bottom section on the rear panel)
p. 7-17 This product information can also be obtained using the *IDN? remote control
command.
1.2 Product Overview
The PAT is a low-noise, highly efficient Constant Voltage (CV)/Constant Current
(CC) automatic crossover power supply that employs a software switching system.
The input power mode is selectable for the three-phase input mode (200 V system) or
single-phase input mode (200 V system).
Capable to expand the system up to a maximum output of 20 kW (in the three-phase
input mode) or 15 kW (in the single-phase input mode) by the master-slave parallel
operation.
The communication function (RS232C) for remote control also comes standard with
the product.
Features
●Selectable input power for the three-phase inputmode (200 V system) or
single-phase inputmode (200 V system)
Possible to operate in the single-phase input mode (200 V system). The input
power mode can be switched from “three-phase input to single-phase input” or
“single-phase input to three-phase input” by the CONFIG setting. (In the single-
phase input mode, output current is limited to 75 % of the rating of three-phase
input mode.)
●Reduction of harmonic current and power transmission loss
The power-factor improvement circuit reduces the effects of harmonic currents
on the input power line. It also suppresses the peak current and reduces the
power transmission loss.

General Description
●Power Factor Correction circuit is equipped
•Reducing the cost of operation
Because of the reactive power is reduced, the power can be used without wasting
of power.
•Downsized input distribution device
The input distribution device (breaker) can be downsized, because the built-in
power-factor correction circuit reduces the required input current.
•Reducing the transmission loss and harmonic current
The effect of harmonic current on the input power is reduced. And the
transmission loss can be reduced by limiting the peak current of the input power
line.
●Master-Slave parallel operation
Up to five power supplies can be connected in parallel to expand the output
power to 20 kW (in the three-phase input mode) or 15 kW (in the single-phase
input mode) by the master-slave parallel operation.
●Output limit function
You can set the upper limit of current and voltage that is applied when setting the
output.
This function is used to prevent setting inappropriate value by mistake.
●Remote interface
Equipped with RS232C as standard. You can select the GPIB, USB or LAN
interface as a factory option.
The remote interface complies with IEEE 488.2 std 1992 and SCPI Specification
1999.0.
●High efficiency and lownoise
High power conversion efficiency has reduced the rise in the internal temperature
and has contributed to the product’s compact and light design.
●Preset memory function of settings
Up to three output setting presets (combination of current and voltage) can be
saved.
You can simply select a preset to set the output without having to set the voltage
and current every time you use the PAT.
●Output on/off delay function
You can set a delay until the output is actually turned on or off after turning the
OUTPUT switch on or off.
For example, this feature is useful if you want to turn the output on/off by setting
a time offset according to the load characteristics.
