  • Page 17: Load Considerations

    Load Considerations Note that the output will become unstable if the following types of loads are connected. Loads with peak current or pulse-shaped current The PWX series only indicates mean values. Even when the indicated value is less than or equal to the set constant current, the peak values may exceed the set constant current.
  • Page 18 Load Considerations Loads with accumulated energy Connecting a load with accumulated energy, such as a battery, to the PWX series may cause current to flow from the load to the internal circuit of the PWX series. This current may dam- age the PWX series or reduce the life of the load.

  • Page 24: Local Sensing

    Sensing Local sensing By factory default, the PWX series is set to local sensing (the rear panel sensing connector is hard wired). The sensing point during local sensing is the output terminal. This method does not compensate for the voltage drop in the load cable, so use this method when the load cur- rent is small or when you do not need to consider the load effect voltage.

    If an alarm still occurs even after you have corrected all the causes of alarms, the PWX series may be malfunctioning. Stop using it immediately, and contact your Kikusui agent or distribu- tor.
  • Page 38 Protection Functions and Alarms Overvoltage protection (OVP), overvoltage protection 2 (OVP2), and overcurrent protection (OCP) The overvoltage protection (OVP) function is activated under the following conditions. • When the output terminal voltage exceeds the set voltage (OVP trip point). • When the load or the PWX series is malfunctioning. The overvoltage protection 2 (OVP2) function is activated under the following conditions.
  • Page 39 Protection Functions and Alarms  Checking OVP and OCP operation The OVP and OCP functions are designed to protect the load. If you use the CONFIG settings to limit the voltage setting (CF15: ON), you will no longer be able to set the output voltage to a value that exceeds the OVP trip point. This means that you won’t be able to check the operation of the OVP function.
  • Page 40 Protection Functions and Alarms Undervoltage limit (UVL) This protection function is activated when you attempt to set the output voltage to a value that is lower than the set undervoltage limit (the UVL trip point). In other words, it prevents you from setting the output voltage to a value lower than the set limit.

    Preset Memory Function The PWX series has the preset memory that stores three sets of the following settings: the voltage, the current, the OVP, the OCP, and the UVL. You can recall the stored set from the preset memory whenever you need. To select the preset memory that you specify for saving or recalling a set of settings, press A, B, or C key while holding down SHIFT key.

    The PWX series is calibrated before shipment. To maintain long-term performance, we rec- ommend periodic calibration. For calibration, contact your Kikusui agent or distributor. If you are going to calibrate the PWX series yourself, follow the procedures below. All of the calibration items of the PWX series are described.

  • Page 91: Calibration Procedure

    Calibration Calibration procedure Use the “KIKUSUI PWX calibration” application software included on the CD-ROM to cali- brate the PWX series. The system requirements for the “KIKUSUI PWX calibration” is below.  OS • Windows7 (x86/ x64) • Windows Vista (x86/ x64) •...

    Isolated Analog Interface Factory Option This chapter describes the isolated analog interface and variable internal resistance feature, which are factory options.

  • Page 114: Isolated Analog Interface

    Isolated Analog Interface The isolated analog interface is an internal option card that makes it possible to use analog signals to control the PWX Series. This option is installed inside the PWX before shipment. You can use a signal that is isolated from the reference potential of the PWX to perform the following the following types of control.

    Isolated Analog Interface terminals. If they 84-61-8209 are damaged or lost, contact your Kikusui agent or distributor. The isolated analog interface connector, which is on the rear panel, can be split into two parts: the socket (attached to the PWX) and the detachable plug. To minimize the influence of noise, we recommend that you use shielded twisted pair wires to make connections.

    Variable Internal Resistance Feature The variable internal resistance feature enables you to easily simulate the internal resistance of rechargeable batteries, solar batteries, fuel cells, and the like. By setting the internal resis- tance value in constant voltage (CV) mode, you can decrease the output voltage according to the output current.
