    Inrush Current When the power switch is turned on, the maximum inrush cur- rent of 120 A may flow. In particular, with a system using mul- tiple models of the product, when the power switch is turned on at the same time, make sure that there is enough of a margin, taking into consideration the capacity of the distributor panel or the AC power line.

  • Page 37: When The Load Current Has Peaks Or Is

    3.3.1 When the Load Current Has Peaks or is Pulse- shaped The current meter on the PMP 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.

  • Page 38: When The Load Generates A Reverse Current To

    3.3.2 When the Load Generates a Reverse Current to the Power Supply The PMP cannot absorb reverse current from the load. There- fore, if a regenerative load (such as an inverter, converter, or transformer) is connected, the output voltage increases and becomes unstable.

  • Page 39: When The Load Has Accumulated Energy Such As

    3.3.3 When the Load Has Accumulated Energy Such As Batteries When connecting to a load that has stored energy such as a bat- tery, a large current flows from the load to the product's internal capacitor through a protection diode in an internal output con- trol circuit, and depending on the situation, the product may burn out or the load's working life may be reduced.

  • Page 40: Constant Voltage (Cv) And Constant Current (Cc) Power Supplies

    Constant Voltage (CV) and Constant Current (CC) Power Supplies The product has functions for constant voltage power supply to maintain a fixed/regularized output voltage, and for constant current power supply that maintain a fixed output current, even as the load changes. The state of operation for constant voltage supply is called “CV mode”, and for constant current supply, “CC mode”.
  • Page 41 because the operating point is within the range. At this time, the current setup value I becomes the current limit value. When operating in CV mode, the output voltage is maintained at the voltage setup value. The output current is determined by the relation I=V , and is reduced to a value below the cur- rent limit value I...

  • Page 51: Basic Operation

    Basic Operation First, output setting methods are explained. Then, methods for using constant voltage power supply and constant current power supply are explained. 4.3.1 Setting the Output About voltage/current setting digit The PMP can select and set the setting digit when output volt- age and output current are being selected.
  • Page 52 • When the OUTPUT switch is turned on, the SET switch being lit means that the setting value is displayed and the outputs will differ. • Hereafter, the digits are numbered from the side of the most significant digit (leftmost). Select CH3 of the output display selection switches.
  • Page 53 Depress the CURRENT switch one more time and select digit 3 of the voltmeter. Turn the rotary knob right to set the value to “5”. The current setting above is finished. Similar steps are performed for other output settings. • If turning the rotary knob causes the set digit to go above “9”, or below “0”, the value of the digit that is higher by one step is changed.

  • Page 54: Using The Unit As A Constant Voltage (Cv) Or Constant Current (Cc) Power Supply

    4.3.2 Using the Unit as a Constant Voltage (CV) or Constant Current (CC) Power Supply When you use the unit as a constant voltage power supply, the current setting value becomes the current limit value used to Page 3-6 make current flow to the load. When you use the unit as a constant current power supply, the voltage setting value becomes the voltage limit value that can be applied to the load.
  • Page 55 Select the digit that you want to set by depressing the CURRENT switch and make the setting using the rotary knob. Set the current value. Repeat steps 5-7 for other channels. Depress the OUTPUT switch. The OUTPUT LED on the display is lit, and voltage/current is out- put to each output terminal.

  • Page 56: Connecting The Load

    Connecting the Load This section describes the wire used to connect the PMP to the load, and the connection to the output terminal. CAUTION • Before connecting to the load, confirm that the POWER switch is turned on, and that the OUTPUT is turned off.

  • Page 57: Dependence Of Allowable Cable Current On The Maximum Allowable Insulator Temperature

    + (pos.) and – (neg.) output lines side by side or bundling them together is more effective against unwanted noise. The Kikusui-recommended currents shown in Table 4-2 are allowable current that have been reduced in con- sideration of the potential bundling of load cables.

  • Page 58: Connecting To The Output Terminal

    Limitations of the sensing function Because wires have resistance, voltage drop in wires becomes greater as the wire becomes longer or the current becomes larger. This causes the voltage applied at the load end to be smaller. The PMP has a sensing function that compensates for this voltage drop, but compensation of up to approximately 0.3 V is available for a single line.

  • Page 62: Tracking Function (Tracking)

    Tracking Function (TRACKING) The tracking function permits changing multiple channels simul- taneously in accordance with changes in a reference channel. If performed within an active area, it can be varied from 0 V (or 0 A) to the rated voltage (or the rated current). There are the following two kinds of tracking functions.
  • Page 63 Tracking function 1 (absolute value variable) When this tracking function is activated, the output of each channel other than the reference channel, which is selected using the output display selection switch, varies by the same value (absolute value) as the variation in the reference channel. Note that the variation of the output of each non-reference channel occurs with respect to its voltage or current setting.
  • Page 64 Example 1) [CH1] [CH2] Reference voltage 10.00 V 3.00 V Set TRACKING function 1. Increase CH1 by 4 V. CH2 increase stops at the maximum voltage, 14.00 V 6.18 V but its variation result, which is 3 V + 4 V = 7 V, is saved.
  • Page 65 Tracking function 2 (variable ratio) When this tracking function is activated, the output of each channel other than the reference channel, which is selected using the output display selection switch, varies by the same percentage (ratio) as the variation in the reference channel. Note that the variation of the output of each non-reference channel occurs with respect to its voltage or current setting that is assumed to be 100%.
