    Turning the Power On Turn the power on without the load connected. CAUTION • The CONFIG parameters can be set so that the out- put is automatically turned on when the POWER switch is turned on. When this function is enabled, the PWR powers up with the output turned on even if the output was off when the PWR was turned off the last time.

  • Page 36: Inrush Current

    If the POWER switch is turned on for the first time after pur- chasing the PWR, the PWR starts up in a factory default condi- Page 4-32 tion. For all other cases, the PWR starts up using the settings that existed when the POWER switch was turned off the last time.

  • Page 37: Chapter 3 Connecting The Load

    Connecting the Load This chapter describes the consideration to be given to the load, explains how to connect the load wires, and explains how to connect to the output terminals.

  • Page 38: Load Considerations

    Load Considerations Note that the output will become unstable if the following types of loads are connected. • Load current with peaks and pulse-shaped load current. • Load that generates reverse current to the power supply. • Load with accumulated energy. Load current with peaks and pulse-shaped load current The PWR indicates mean values.
  • Page 39 Load that generates reverse current to the power supply The PWR 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. For these types of loads, connect a resistor (R ) as shown in Fig 3-3 to bypass the reverse current.
  • Page 40 Load with accumulated energy Connecting a load with accumulated energy, such as a battery, to the PWR may cause current to flow from the load to the internal circuit of the PWR. This current may damage the PWR or degrade the service life of the load. For this type of loads, connect a reverse-current-prevention diode (D ) between the PWR and the load in series as shown...

Short the output terminal. Turn the POWER switch on. Set the output voltage to a value less than the OVP trip point.

  • Page 69: Other Protection Functions

    4.6.3 Other Protection Functions Overpower protection (OPP) This function is activated when a condition that exceeds approximately 110 % of the rated output power persists for a certain period (approximately 2 seconds) such as due to a tran- sient load change. You can select whether to trip the breaker (C-8: 0/1) when the OPP function activates.

    Output Terminal Insulation Note the following points and insulate the output terminals. WARNING • Possible electric shock. For safety reasons, even if the output terminal is grounded, make sure the insulation capacity of the output termi- nal (including the sensing terminal) is greater than the isolation voltage of the PWR.

  • Page 87: When The Output Terminal Is Not Grounded (Floating)

    5.3.1 When the Output Terminal Is Not Grounded (Floating) The output terminal of the PWR is isolated from the protective conductor terminal. By connecting the GND wire of the power cord to the ground terminal of the switchboard, the chassis of the PWR is set to ground potential as shown in Fig.

  • Page 88: When The Output Terminal Is Grounded

    5.3.2 When the Output Terminal Is Grounded If the positive output terminal is connected to the chassis termi- nal, the terminal is at ground potential as shown in Fig. 5-5. Therefore, the wires and load that are connected to the output terminal (including the sensing terminal) only require an insu- lation capacity that is greater than the maximum output voltage of the PWR with respect to the chassis.
  • Page 89 Precautions to be taken when using the external voltage (Vext) Be sure that the output is not shorted as shown in Fig. 5-6 and Fig. 5-7. CAUTION The signal wire may burn out. • Leave the Vext output floating. • If you are connecting the shield at the Vext end, do not connect the shield to the output terminal of the PWR.

  • Page 90: Output Voltage Control

    Output Voltage Control This section explains the method used to control the output voltage using an external voltage (Vext) in the range 0 V to approx. 10 V or an external resistor (Rext) in the range 0 kΩ to approx. 10 kΩ. If no load is connected, it takes a long time for the output voltage to fall.
  • Page 91 Connecting the external voltage (Vext) Use a low-noise and stable voltage source for Vext. The noise in Vext is multiplied by the amplification factor of the PWR and appears at the output. Thus, the output ripple noise may not meet the PWR’s specifications. To minimize the influence of noise on the output, use a two- core shielded wire or a twisted-pair wire to connect the control terminals and Vext.

  • Page 95 External voltage source (Vext) connection Use a low-noise and stable voltage source for Vext. The noise in Vext is multiplied by the amplification factor of the PWR and appears at the PWR output. Thus, the output ripple noise may not meet the PWR’s specifications. To minimize the influence of noise on the output, use a two- core shielded wire or a twisted-pair wire to connect the control terminals and Vext.
