WARNUNG: Beim Einsatz eines Netzteils mit einer Nenn-Ausgangsspannung von mehr als 60VDC besteht Stromschlaggefahr.

  • Page 37: Current Carrying Capacity

    3.9.2 Current Carrying Capacity Two factors must be considered when selecting the wire size: 1. Wires should be at least heavy enough not to overheat while carrying the power supply load current at the rated load, or the current that would flow in the event the load wires were shorted, whichever is greater.

  • Page 38: Wire Termination

    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 160V to 650V Models The 160V to 650V models have four terminal wire clamp output connector. The two left terminals are positive outputs and the other two right terminals are the negative outputs. The connector requirements are as follows: 1. Connector type: IC 2,5/ 4-G-5,08 (Phoenix). 2.

    Bei Einsatz einer Stromversorgung größer 60VDC Nennspannung besteht eine potentielle Gesundheitsgefahr durch elektrischen Schlag. Schalten Sie keine Stromversorgung mit einer Ausgangsspannung größer 60VDC EIN, ohne dass die Schutzabdeckung des Ausgangssteckers montiert ist. Stellen Sie sicher, dass die Schutzabdeckung des Ausgangssteckers fachgerecht montiert wurde und wie in Bild 3.5.

  • Page 41: Connecting Multiple Loads, Radial Distribution Method

    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. The sense wires should be connected to the power supply output terminals or to the load with the most critical load regulation requirement.

  • Page 42: Grounding Outputs

    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

    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.

Split connection of the power supplies gives positive and negative output voltage. WARNING When power supplies are connected in series, and the load or one of the output terminals is grounded, no point may be at a greater potential of +/- 650VDC from ground.

  • Page 61: Series Connection For Positive And Negative Output Voltage

    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

    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

    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 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.

    7.12 SCPI Subsystem Commands Subsystem commands are specific to power supply functions. They can be a single command or a group of commands. 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.
  • Page 97 OUTPut:PROTection:FOLDback Foldback mode is used to disable the output when a transition is made between the operation modes. 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.
  • Page 98 OUTPut:TTLTrg:MODE Sets the operation of the Trigger Out signal to either OFF, Function Strobe or Trigger mode. Programming Mode NONE, FIX: • In TRIG mode, trigger is generated when output status changes. • In Function Strobe mode, an output pulse is generated automatically any time an output parameter such as output, voltage or current is programmed.

    9.2 Power Supply Status Structure Status and Fault Register shows the status register structure of the power supply. The Standard Event, Status Byte, and Service Request Enable registers and the Output Queue perform standard functions as defined in the IEEE 488.2 Standard Digital Interface for Programmable Instrumentation. The Operation Status and Questionable Status registers implement status functions specific to the power supply.

  • Page 125: Standard Event Status Group

    9.6 Standard Event Status Group 9.6.1 Register Functions This group consists of an Event register and an Enable register that are programmed by COMMON commands. The Standard Event register latches events relating to interface communication status. It is a read-only register that is cleared when read. The Standard Event Enable register functions similarly to the Enable registers of the Operation and Questionable status groups.

  • Page 126: Status Byte Register

    9.6.3 Status Byte Register This register summarizes the information from all other status groups as defined in the IEEE 488.2 Standard Digital Interface for Programmable Instrumentation standard. The register can be read either by a serial poll or by *STB?. Both methods return the same data, except for bit 6. Sending *STB? return MSS in bit 6, while polling returns RQS in bit 6.

  • Page 127: Output Queue

    9.6.5 Output Queue The Output Queue is a first-in, first-out (FIFO) data register that stores power supply-to-controller messages until the controller reads them. Whenever the queue holds one or more bytes, it sets the MAV bit (4) of the Status Byte register. If too many unread error messages are accumulated in the queue, a system error message is generated.
