Features

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 product’s 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.

6 Connect the power cable by matching the U, V, W, and (GND) of the switchboard.

Turning the Power On

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.

Turning the POWER switch on

1 Check that the power cable is correctly connected.
2 Raise the lever and turn the POWER switch on.
3 Check the firmware version on the front panel display.
The voltmeter and ammeter show the PAT firmware version for approximately 1 second. The measuring value will be shown after the firmware version is displayed.

If the POWER switch is turned on for the first time after purchasing the PAT, the PAT starts up in a factory default condition.
An inrush current flows up to 100 Amax. (40 Amax. for 400 V input model) when the POWER switch is turned on. In 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 power-on, follow the corresponding remedy. If the remedy does not correct the problem, contact your Kikusui agent or distributor.
