    3.2.3 Connecting Multiple Loads, Radial Distribution Method Figure 3–3 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. Load lines, Twisted pairs, shortest length possible POWER...

  • Page 37: Constant Voltage Mode And Voltage Setting

    3.2.5 Constant Voltage Mode and Voltage Setting In Constant Voltage mode, the power supply regulates the output voltage at the selected value, while the load current varies as required by the load. While the power supply operates in Constant Voltage mode, the CV indicator on the display illuminates.

  • Page 38: Automatic Crossover

    Adjust the output current, when the power supply output is enabled (Output On) or disabled (Output Off). There are three options to set output voltage: (a) When the output is enabled, rotate the Current encoder knob to program the output current.

  • Page 39: Safe-Start And Auto-Restart Modes

    3.2.9 Safe-Start and Auto-Restart Modes At AC turn on, the power supply can start at the last setting of the Output Voltage and Current limit with the output enabled (Auto-restart), or it can start with the output disabled (Safe mode). Press the Configuration button.

  • Page 40: Over Voltage Protection

    3.3.2 Over Voltage Protection The OVP circuit protects the load in the event of a remote or local programming error or a power supply failure. The protection circuit monitors the voltage at the power supply sense points thus providing the protection level at the load. Upon detection of an Over Voltage condition, the power supply output will shut down.

  • Page 41: Under Voltage Protection And Under Voltage Limit

    3.3.3 Under Voltage Protection and Under Voltage Limit The UVL function prevents output voltage setting below the UVL set value, and prevents an adjustment of the output voltage below a certain limit. The UVP function prevents power supply operation, if the output voltage is below the UVL set value.

  • Page 42: Foldback Protection

    3.3.4 Foldback Protection Foldback protection will shut down the power supply output if power supply operation mode crosses over from CC to CV or from CV to CC, according to a selected operation mode. There are three states of Foldback protection. •...

  • Page 43: Protection Delay

    3.3.5 Protection Delay Foldback protection delay is the time between feedback transition (CV to CC transition or vice versa) event occurrences to output shutdown. UVP protection delay is the time between UVL crossover point events to output shutdown. NOTE At output OFF -> ON transition, additional 500ms delay is added. Total protection delay = 500ms + delay setting.

  • Page 44: Series Operation

    Series Operation Power supplies of the same model can be connected in series to obtain an increased output voltage. 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 +/- 200VDC from ground for models up to 100VDC rated output and +/- 600VDC from ground for models 150 ~ 600VDC rated output.

  • Page 45: Series Connection For Positive And Negative Output Voltage

    3.4.2 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 46: Daisy-Chain Connection

    Programming via serial communication ports The Communication ports are referenced to the (RS232/RS485, USB): COM_SELV, which is isolated from the power supply output potential. Therefore, power supplies connected in series can be chained using the Remote-In and Remote- Out connectors. Refer to section 2.4 for details. Daisy-Chain Connection It is possible to configure a multiple power supply system to shut down all units when a fault condition occurs in one of the units.

  • Page 90: Input Buffer Requirements

    5.7.8.4 Input Buffer Requirements With a controller using TCP or UDP sockets, the Power Supply can receive commands much faster than it can process. To make sure the LAN is not overloaded, it is required that the controller sometimes sends a query and then waits for the response. The response is the acknowledgement from the Power Supply that it has finished processing all commands.

  • Page 91: Using Udp Sockets

    5.7.8.7 Using UDP Sockets This is a simpler socket type with reduced network traffic. It is a ‘connectionless’ protocol because messages are sent and there is no acknowledgement that they have been received. Open UDP socket port 8005 to send SCPI commands. Responses to queries are sent back automatically with a line-feed terminator and carriage return appended.

    7.2.7 Service Request Enable Group Structure Service request enable group register summarizes questionable condition group, standard event status group and operational condition group events, if these are enabled. The group also contains busy bit and message available bit and service request bit. The register can be read by *STB? Command.

  • Page 166: Determining The Cause Of A Service Interrupt

    7.2.8 Determining the Cause of a Service Interrupt A service request (SRQ) is set if the contents of at least one of the event registers has changed (from logical zero to logical one). To determine the reason for an SRQ, perform the following actions: Poll by *STB? query to determine which bits are active in the service request enable status byte.

    can be set by the user to enable SRQ (Service request) in case a condition change occurs. Event registers latch condition registers state if the corresponding Enable registers are set to logical one. Event registers remain set (latched) until the user reads the register, reading the register clears its values until the next event.

  • Page 169: Operational Group (Status Register) Structure

    7.3.3 Operational Group (Status Register) Structure Operational condition status register group holds a snapshot of the actual status state of the power supply at a present time. Power supply status might quickly change its condition before the controlling PC detects it. Events can be stored in the Event register if the Enable register allows it. Refer to General Status Register Commands (section 5.10.9) set.

  • Page 170: Execution Error ("Exx")

    7.3.5 Execution Error (“Exx”) Power Supply responds with an execution error if it receives a valid command, but it cannot execute the command at that time, because another setting prevents it. The execution error response format is ‘Enn<CR>‘ where ‘nn’ is ‘01’ to ‘08’. The following error commands are available: E01 Cannot program voltage above the OVP setting (*1) E02 Cannot program voltage below the UVL setting (*2)

  • Page 171: Chapter 8: Ieee Option

    CHAPTER 8: IEEE OPTION General The internal factory, General Purpose Interface Bus (GPIB), installed as an option, allows operation of the Power Supply from a controller/computer via IEEE-488. The interface allows the user a remote control of the Power Supply, including output voltage, current setting and monitoring, protection setting, trigger, waveform list operation, Power Supply status, SRQ reporting and more.

  • Page 172: Multi Drop Connection

    Multi Drop Connection One IEEE Interface can control more than one Power Supply. A maximum of 31 units can be connected via RS485 interface to a Power Supply with the installed IEEE option. Refer to Figure 8–2.The Power Supply connected to a PC via the GPIB cable must be configured to an IEEE communication interface, the other must be configured to RS485 interface.

  • Page 173: Communication Cables

    Communication Cables • GPIB cable - Use standard IEEE-488, 26 AWG GPIB cable up to 3 meters in length. • RS485 link cable - Use serial link cable with RJ-45 shielded connectors (P/N: GEN/RJ45). IEEE Controller Configuration A typical IEEE controller is a personal computer with an IEEE interface card. Each card vendor supplies its own configuration instructions and interface software.
