  • Page 11: Load And Cable

    Load and cable This chapter describes consideration to be given to the load and explains how to connect the load wires.

  • Page 12: 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 13 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 14: 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 an allowable temperature higher than 85 °C of the covering materials.
  • Page 15 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 1-1 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.

    Phase input mode The input power mode of the PAT (4kW type) can be switched to either three-phase input or the single-phase input. Before starting the operation, confirm the status of phase input mode. To verify the p. 31 status and setting of the phase input mode, refer to the ”2.7 CONFIG Settings”. The principal of difference in specifications for the phase input mode are described “Specification”...

  • Page 19: Measured Value Display And Setting Display

    Measured Value Display and Setting Display The panel display has two modes. One mode displays the measured values of the output voltage and output current, and the other mode displays the settings. These two modes can be distinguished by the on/off state of the SET, OVP•OCP, and CONFIG keys.

  • Page 20: Output Operation

    Output Operation The OUTPUT switch is a toggle switch. When you press the OUTPUT switch and the output turns on, the OUTPUT LED illuminates. When you press the OUTPUT switch and the output turns off, the OUTPUT LED turns off. If the output is turned on, the present setting is output.
  • Page 21 Output on/off delay functions You can set a delay (0.1 s to 10.0 s) until the output is actually turned on or off after p. 33 you turn the OUTPUT switch on or off. This function is useful if you want to turn the output on/off by setting a time offset according to the load characteristics.

  • Page 22: 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 23 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 24: Using The Pat As A Cv Or Cc Power Supply

    Using the PAT as a CV or CC Power Supply When using the PAT as a constant voltage power supply, the preset current is the limit that can flow through the load. When using the PAT as a constant current power supply, the preset voltage is the limit that can be applied to the load.

  • Page 26: Overvoltage Protection (Ovp) And Overcurrent Protection (Ocp)

    If you cannot clear the alarm even when all of the causes of the alarm occurrence are eliminated, the PAT may have malfunctioned. If this happens, stop using the PAT and contact your Kikusui agent or distributor. The cause of the alarm occurrences are described in the protection functions.
  • Page 27 The OVP operates on the output terminal voltage. If you want to activate the function on the voltage across the load, set the OVP trip point by considering the voltage drop in the load cable. Press the OVP•OCP key. • The OVP OCP key LED illuminates, and the specified OVP/OCP trip point is shown on the display.
  • Page 28 When the setting value of output voltage exceeds OVP trip point, the ALARM LED on the front panel display illuminates and either of the POWER switch or the output will be turned off (Depending on the CONFIG settings: CF28). When the POWER switch is turned off, the ALARM LED illuminates even the power turns off, and the overvoltage protection (OVP) power-off display will be displayed for about a few seconds (4 kW type:4 to 5 seconds, 8 kW type:10 to 15 seconds).

  • Page 41: Preset Memory Function

    Preset Memory Function The PAT has a function that stores up to three combinations of voltage setting and current setting. You can store a combination by selecting memory key A (PRESET A), B (PRESET B), or C (PRESET C). RECALL keys allow you to recall any of the three preset memory values. When the phase input mode is changed to the single-phase input mode from the three-phase input mode for 4kW type, the setting value of the output current and the overcurrent protection (OCP) is limited to 75 % of the three-phase input mode.

  • Page 42: Lock Function

    If the voltage or current setting is limited in the CONFIG settings (CF29 or CF30: ON) and the recalled preset memory values exceed the OVP or OCP trip point, the output setting is limited to approximately 95 % of the OVP or OCP trip point. Then, PRESET A, B, or C LED corresponding to the preset memory that was recalled illuminates for approximately 1 second and turns off.
