  • Page 22: Load Considerations

    Load Considerations Note that the output will become unstable if the following types of loads are connected. Load with peaks and pulse-shaped current The PAT indicates only mean values. Even when the indicated value is less than the preset current value, the peak values may actually exceed the preset current value. If this happens, the PAT is instantaneously put into constant-current operation mode, and the output voltage drops accordingly.
  • Page 23 CAUTION • Use a resistor with sufficient rated power for resistor R • If a resistor with insufficient rated power for the circuit is used, resistor R may burn out. Load with accumulated energy Connecting a load with accumulated energy, such as a battery, to the PAT may cause current to flow from the load to the internal circuit of the PAT.

  • Page 24: Load Cable

    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 heat resistance higher than 85 °C of the covering materials.
  • Page 25 However, installing the + (pos.) and - (neg.) output wires of the load cable side by side or bundling them together is more effective against unwanted noise. The Kikusui-recommended currents shown in Table 2-1 are allowable current values that have been reduced in consideration of the potential bundling of load cables. Use these values as a guideline when connecting load cables.

  • Page 33: Constant Voltage (Cv) And Constant Current (Cc) Power Supplies

    Constant Voltage (CV) and Constant Current (CC) Power Supplies The PAT has a constant voltage power supply function that maintains the output voltage at a constant level and a constant current power supply function that maintains the output current at a constant level even when the load changes. The condition in which the PAT is operating as a constant voltage power supply is called the constant voltage (CV) mode.
  • Page 34 When operating in CC mode, the output current is maintained at the preset current. × Output voltage V is determined by the relationship defined by the equation V = Is . It is a voltage less than voltage limit Vs. In this mode, the actual voltage that is applied is not necessarily equal to the specified value.

  • Page 62: When The Output Terminal Is Not Grounded (Floating)

    4.3.1 When the Output terminal Is Not Grounded (Floating) The output terminal of the PAT is isolated from the protective conductor terminal. By connecting the GND wire of the power cable to the ground terminal of the switchboard, the chassis of the PAT is set to ground potential as shown in Fig.4-3. Pins 10 through 26 of the J1 connector on the rear panel (for external control and output monitoring) are at approximately the same potential as the - (neg.) output terminal of the PAT.

  • Page 107: Calibration

    The PAT is shipped after carrying out appropriate calibrations. We recommend periodic calibration to maintain the performance over an extended period. For calibration, contact your Kikusui agent or distributor. If you are going to calibrate the PAT yourself, follow the procedures below.

  • Page 108: Calibration Procedure

    Environment Perform calibration under the following environment. • Temperature: 23 °C ± 5 °C • Relative humidity: 80 % or less To minimize the calibration error due to initial drift, warm up the PAT for at least 30 minutes before calibration. In addition, warm up the DVM and shunt resistor adequately.
