Features
About the PAT-T Documentation
The PAT-T Series is equipped with the following features.
• 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.
• Master-Slave parallel operation
Up to five power supplies can be connected in parallel to expand.
• 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. Because the LAN interface complies with the LXI
standard, the construction of a highly cost-effective system is
possible.
• High efficiency and low noise
The PAT is a highly efficient, low-noise power supply that employs
a software switching system. High power conversion efficiency
has reduced the rise in the internal temperature and has
contributed to the productʼs compact and light design.
• Downsized input distribution device
The input distribution device (breaker) can be downsized,
because the built-in power-factor improvement circuit reduces the
required input current.
• 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.
• Selectable input power for the three-phase input mode or
single-phase input mode (Only 4 kW type)
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.

Connecting the Power Cable
This product conforms to IEC Overvoltage Category II (energyconsuming equipment that is supplied from a fixed installation).
WARNING
Possible electric shock.
• Turn off the switchboard breaker before making the
connection.
• This product is an IEC Safety Class I equipment
(equipment with a protective conductor terminal). Be
sure to ground the product to prevent electric shock.
• Connect the ground terminal to earth ground.
• Be sure to have a qualified engineer connect the
power cable to the switchboard.
CAUTION
Inside the power supply, an appropriate protective circuit is
connected to the input terminal. Be sure to connect the wires
correctly by following the instruction for the connection.
ー Note ー
The POWER switch of the product can be used to disconnect
the product from the AC line in an emergency. Provide adequate
space around the POWER switch so that the POWER switch can
be turned off at any time.
A power cable is not included with this product. Use a power
cord that conforms to this productʼs rated AC input voltage and

Turning the Power On
Indicates the version
Firmware version
CAUTION
The CONFIG parameters can be configured so that the
output is automatically turned on when the POWER switch
is turned on. When this function is enabled, the PAT powers
up with the output turned on even if the output was off when
the PAT was turned off the last time. However, there is a
possibility that a load may break, if you connect a different
load and turn the POWER and output on simultaneously
without changing the OVP and OCP settings to appropriate
values.
Switching the phase input mode (Only 4 kW
type)
On the 4 kW type, you can use CONFIG parameter CF31 to
switch the input mode (single-phase input or three-phase
input).
■ Three-phase input mode
The phase input mode is set for the three-phase input mode
at the time of factory shipment. Therefore, when the power is
turned on, the three-phase input mode is activated.
■ Single-phase input mode
Set CONFIG parameter CF31 to 1PHA to select single-phase
input mode. Press the POWER switch to turn on while pressing
the STORE key. Once the single-phase input mode is set, the
product will be started in the single-phase input mode next
time just by pressing the POWER switch. If the input power
connected to the single-phase input wiring, and press the
POWER switch without pressing the STORE key, the PAT will
detect the open-phase by the function of “Input open-phase
protection (PHASE)
”, and the PAT will not be turned on.
particular, check that sufficient current capacity is available in
the AC power line and the switchboard if you are using multiple
PATs and turning on the POWER switches simultaneously.
If front panel display shows indicated the following after poweron, follow the corresponding remedy. If the remedy does not
correct the problem, contact your Kikusui agent or distributor.

The PAT stores the panel settings (excluding output on/off

If the POWER switch is turned off immediately after changing
the settings, the last settings may not be stored.
CAUTION
When turning the POWER switch off and then back on, allow
at least 10 seconds (40 seconds for 400 V input model) after
the fan stops. Repeated ON/OFF of the POWER switch at
short intervals can cause damage to the inrush current limiter
or shorten the service life of the POWER switch and the
internal input fuse.

Connecting the Load
Note that the output will become unstable if the following types
of loads are connected.
• Load with peaks and pulse-shaped current
• Load that generates reverse current to the power supply
• Load with accumulated energy
Load Cable
WARNING
To prevent the possibility of fire.
• Use a load cable with sufficient current capacity with
respect to the rated output current of the PAT.
• The output terminal and its area nearby gets very high
temperature, use the cable with sufficient an allowable
temperature higher than 85 C of the covering
materials.
Possible electric shock.
• Use a load cable with
a higher voltage rating than the
isolation voltage of the PAT. For the isolation voltage
of each model, see "Specifications."
