  • Page 38: Wire Termination

    NATIONAL INSTRUMENTS 3.9.3 Wire Termination The wires should be properly terminated with terminals securely attached. DO NOT use non terminated wires for load connection at the power supply. CAUTION: When local sensing, a short from +LS or +S to -V or -S or -LS, will cause damage to the power supply. Reversing the sense wires might cause damage to the power supply in local and remote sensing.
  • Page 39 NATIONAL INSTRUMENTS CAUTION: Ensure that the load wiring mounting hardware does not short the output terminals. Heavy connecting cables must have some form of strain relief to prevent loosening the connections or bending the bus-bars. 20V to 100V Models Refer to Fig.3-4 for connection of the load wires to the power supply bus-bars and to Fig.3-5 for mounting the bus-bars shield to the chassis.

    NATIONAL INSTRUMENTS 3.9.7 Connecting Single Loads, Local Sensing (default) Fig.3-6 shows recommended load and sensing connections for a single load. The local sense lines shown are default connections at the rear panel J2 sense connector. Local sensing is suitable for applications where load regulation is less critical.

  • Page 41: Connecting Multiple Loads, Radial Distribution Method

    NATIONAL INSTRUMENTS 3.9.9 Connecting Multiple Loads, Radial Distribution Method Fig.3-8 shows multiple loads connected to one supply. Each load should be connected to the power supply’s output terminals using separate pairs of wires. It is recommended that each pair of wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation.

  • Page 42: Grounding Outputs

    NATIONAL INSTRUMENTS 3.9.11 Grounding Outputs Either the positive or negative output terminals can be grounded. To avoid noise problems caused by common-mode current flowing from the load to ground, it is recommended to ground the output terminal as close as possible to the power supply chassis ground. Always use two wires to connect the load to the power supply regardless of how the system is grounded.

  • Page 43: Local Sensing

    NATIONAL INSTRUMENTS 3.10.2 Local Sensing The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the output voltage. Refer to Table 3-4 for J2 terminals assignment. With local sensing, the output voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore it is recommended only for low load current applications or where the load regulation is less critical.

  • Page 44: J2 Sense Connector Technical Information

    NATIONAL INSTRUMENTS CAUTION: When using shielded sense wires, ground the shield in one place only. The location can be the power supply chassis or one of the output terminals. Use remote sense where the load regulation at the load end is critical. In remote sense, the power supply will compensate for voltage drop on the load wires.

    NATIONAL INSTRUMENTS 5.4.2 Series Connection for Positive and Negative Output Voltage In this mode, two units are configured as positive and negative output. Set the current limit of each power supply to the maximum that the load can handle without damage. It is recommended that diodes be connected in parallel with each unit output to prevent reverse voltage during start-up or in case one of the units shuts down.

  • Page 62: Parallel Operation

    NATIONAL INSTRUMENTS 5.5 Parallel Operation 5.5.1 Introduction Up to six units of the same Voltage and Current rating can be connected in parallel to provide up to six times the output current capability. One of the units operates as a master and the remaining units are slaves.

  • Page 63: Slave Unit Set Up

    NATIONAL INSTRUMENTS 5.5.2.2 Slave Unit Set Up When Slave mode is selected the power supply enters Current programming mode via external Voltage. Voltage and Current programming setting values are set to 105% of range. During operation the slave units operate as a controlled current source following the master output current. It is recommended that the power system is designed so that each unit supplies up to 95% of its current rating.
  • Page 64 NATIONAL INSTRUMENTS Fig.5-5: Parallel operation with remote sensing CAUTION: Make sure that the connection between - Vo terminals is reliable to avoid disconnection during operation. Disconnection may cause damage to the power supply. NOTE: With local sensing it is important to minimize the wire length and resistance. Also the positive and negative wire resistance should be as close as possible to each other to achieve current balance between power supplies.

Groups are comprised of commands that extend one or more levels below the root. Commands followed by a question mark (?) take only the query form. Except as noted in the syntax descriptions, all other commands take both the command and query form.

The power supply will turn off the output after a specified delay if the power supply makes transition into CV mode or into CC mode. This feature is particularly useful for protecting current or voltage sensitive loads.
