  • Page 47: Voltage Drops

    Getting Started To satisfy safety requirements, load wires must be heavy enough not to overheat NOTE when carrying the maximum short-circuit output current of the power supply. If there is more than one load, then any pair of load wires must be capable of safely carrying the full-rated current of the power supply.
  • Page 48: Remote Voltage Sensing Connections

    Getting Started Pulse loading In some applications, the load current varies periodically from a minimum to a maximum value. The constant current circuit limits the output current. Some peak loading exceeding the current limit can be obtained due to the output capacitor. To stay within the specifications for the output, the current limit should be set greater than the peak current expected or the supply may go into the CC mode or unregulated mode for brief periods.
  • Page 49: Figure 1-7 Remote Voltage Sensing Connections

    Getting Started Connect one end of the sensing lead shield to the chassis ground ( ) only. Opening a sensing lead causes the power supply’s output voltage to decrease at the load leads. Observe the polarity when connecting the sensing leads to the load.
  • Page 50 Getting Started CV regulation The voltage load regulation specification in Chapter 7 applies at the output terminals of the power supply. When remote sensing, add 5 mV to this specification for each 1 V drop between the positive sensing point and (+) output terminal due to the change in load current.
  • Page 51: Multiple Loads

    Getting Started Multiple loads When connecting multiple loads to the power supply, each load should be connected to the output terminals using separate connecting wires. This minimizes mutual coupling effects between loads and takes full advantage of the low output impedance of the power supply. Each pair of wires should be as short as possible and twisted or bundled to reduce lead inductance and noise pick- up.
  • Page 52: Operating The Power Supply

    Remote Interface Reference Questionable status register The Questionable Status register provides information about unexpected operations of the power supply. Bit 4 reports a fault with the fan, and bit 13 summarizes questionable outputs for any of the two supplies. For example, if one of the two supplies is in constant voltage mode and due to an overload looses regulation, bit 13 is set (latched).
  • Page 136 Remote Interface Reference Questionable instrument summary register There are two questionable instrument summary registers, one for each supply output. These registers provide information about voltage and current regulation. Bit 0 is set when the voltage becomes unregulated, and bit 1 is set if the current becomes unregulated.
  • Page 137: Standard Event Register

    Remote Interface Reference Standard event register The Standard Event register reports the following types of instrument events: power on detected, command syntax errors, command execution errors, self-test or calibration errors, query errors, or when an *OPC command is executed. Any or all of these conditions can be reported in the standard event summary bit (ESB, bit 5) of Status Byte register through the enable register.
  • Page 138: Status Byte Register

    Remote Interface Reference The standard event register is cleared when: – You execute the *CLS (clear status) command. – You query the event register using the *ESR?

Thus, as shown in Figure 6-3, the voltage would remain perfectly constant in spite of any changes in output current demanded by the load. Figure 6-3 Ideal constant voltage Figure 6-4...
  • Page 184: Figure 6-5 Output Characteristics

    Tutorial Figure 6-5 shows the operating modes of the output of the power supply. The operating point of one supply will be either above or below the line R . This line represents a load where the output voltage and the output current are equal to the voltage and current setting.
  • Page 185: Unregulated State

    Tutorial Unregulated state If the power supply should go into a mode of operation that is neither CV or CC, the power supply is unregulated. In this mode the output is not predictable. The unregulated condition may be the result of the ac line voltage below the specifications.
  • Page 186: Figure 6-6 Simplified Diagram Of Common Mode And Normal Mode Sources Of Noise

    Tutorial The output will also change due to changes in the load. As the load increases the output current will cause a small drop in the output voltage of the power supply due to the output impedance R. Any resistance in the connecting wire will add to this resistance and increase the voltage drop.
  • Page 187: Extending The Voltage And Current Range

    Tutorial Extending the Voltage and Current Range The power supply may be able to provide voltages and currents greater than its rated maximum outputs if the power-line voltage is at or above its nominal value. Operation can be extended up to 3% over the rated output without damage to the power supply, but performance cannot be guaranteed to meet specifications in this region.
