  • Page 36: 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 37 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. This current may damage the PAT or reduce the life of the battery. For this type of loads, connect a reverse-current-prevention diode (D ) between the PAT and the load in series as shown in Fig.3-4.

  • Page 48: 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 49 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 50: Using The Pat As A Cv Or Cc Power Supply (Setting The Output Voltage And Output Current)

  • Page 53: Ovp And Ocp Trip Point Settings

    • When the phase input mode is changed to the single-phase input mode from the three-phase input mode, the setting value of the output current and the overcurrent protection (OCP) is limited to 75 % of the rated value of output current and the overcurrent protection of the three-phase input mode.

  • Page 54: Checking The Ovp Or Ocp Operation

    Checking the OVP or OCP operation The OVP or OCP is a function for protecting the load. Once you set the OVP or OCP trip point, check that the OVP or OCP works before you connect the load by carrying out the procedure below. If the voltage limit setting is enabled in the CONFIG settings (CF29: ON), the output voltage cannot be set higher than the OVP trip point.

  • Page 55: Other Protection Functions

    Turn the CURRENT knob slowly clockwise. When the setting value of output current exceeds OCP 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).

  • Page 196: Tutorial

    Tutorial This section describes the procedures to make measurements through remote control on the PAT. A.6.1 Turning the Power On and Resetting the Instrument When the PAT is turned on, all panel settings are set to the state when it was turned off the last time.

  • Page 197: Output Programming

    A.6.2 Output Programming Voltage and current The output voltage and output current are controlled by the VOLTage and CURRent commands. The output ON/OFF state is controlled by the OUTPut command. ' Set the voltage to 13.5 V :VOLTage 13.5 ' Set the current to 4.5 A :CURRent 4.5 ' Turn the output on :OUTPut ON...

  • Page 198: Using Triggers

    Setting the protection functions The PAT provides overvoltage protection (OVP) and overcurrent (OCP) functions that can be configured. The VOLTage:PROTection and CURRent:PROTection commands are used to set the OVP and OCP, respectively. ' Set the OVP to 16 V :VOLTage:PROTection 16.0 ' Set the OCP to 7.5 A :CURRent:PROTection 7.5 If you want to set the OVP or OCP setting to the maximum or minimum value, you...

  • Page 199: Setting Changes (Sequence 1: Transient

    Setting changes (Sequence 1: TRANsient) Using the TRIGger:SEQuence1 (or TRIGger:TRANsient) subsystem allows the VOLTage and CURRent settings to be synchronized using triggers. This is convenient if you want to synchronize output changes with the action of other instruments such as electronic loads. To reserve triggered settings, use the VOLTage:TRIGgered and FREQuency:TRIGgered commands.

    Output on/off delay function (Sequence 2: OUTPut) The TRIGger:SEQuence2 (or TRIGger:OUTPut) subsystem allows you to use the output on/off delay function.

  • Page 201: Measurement (Sequence 3: Acquire

    Measurement (Sequence 3: ACQuire) The PAT has the capability to return voltage and current measurement values. The easiest way is use the MEASure commands. The trigger function is not used. The MEASure commands immediately start a new measurement. Simultaneity for multi-item measurements are lost, because each MEASure command starts a new measurement.
  • Page 202 trigger subsystem goes to the WTG (Waiting For Trigger) state. When a software trigger is applied with the TRIGger:SEQuence3 or *TRG common command, the measurement action is executed. When an ABORt or an equivalent command is sent without executing the trigger, the measurement action is cancelled, and then the trigger subsystem returns to the IDLE state.

  • Page 203: Auto Continue

    Auto continue To keep the trigger subsystem initiated for multiple actions without having to send an initiate command for each trigger, use the CONTinuous option. This enables measurement data to be automatically refreshed as if the PAT is operating in local mode.

  • Page 204: Status Monitoring

    A.6.4 Status Monitoring The PAT has two mandatory SCPI standard registers, STATus:OPERation and STATus:QUEStionable, in addition to the IEEE488.2 standard registers. Register basics All SCPI registers have standard event/filter architecture, employing CONDition, p. 7-43 EVENt, ENABle, and optionally PTRansition and NTRansition. The CONDition and EVENt are read-only registers working as status indicators, and the ENABle, PTRansition and NTRansition are read-write registers working as event and summary filters.
  • Page 205 PON (Power ON) bit The PON bit (bit 7) in the event status register is set whenever the PAT is turned on. The most common use for the PON is to generate an SRQ at power-on keeping track of unexpected loss of power or power line failure. To do this, follow the steps shown below.

  • Page 206: Error Checking

    A.6.5 Error Checking Error/event queue The SCPI specifications define a standard error reporting scheme, Error/Event Queue. This is a FIFO (First In First Out) queue, which records errors and events. The maximum number of errors/events that the PAT can record is 255. Each error/ event can be read with the SYSTem:ERRor query.
