2 Installation Introduction This section contains instructions for checking and repackaging the supply; bench or rack mounting, connecting the supply to ac input power, and converting the supply from one line voltage to another if required.. Note: All power supplies generate magnetic fields that may affect the operation of other instruments. If your instrument is susceptible to operating magnetic fields, do not locate it in the immediate vicinity of the power supply.
Outline Diagrams Figure 2-1 illustrates the outline shape and dimensions of the cabinet. 6023A ONLY 6028A ONLY Figure 2-1. Outline Diagram Bench Operation The supply cabinet has plastic feet, which are shaped to ensure self-aligning when stacked with other Agilent Technologies System II cabinets. Rack Mounting The supply can be mounted in a standard 19-inch rack enclosure. Rack mounting accessories for these units are listed in the ACCESSORIES paragraph in Section I.
Power Connection Caution: Connection of this supply to an ac power source should only be performed by an electrician or other qualified person. Before connecting the supply to the ac power source, check the label on the rear panel to ensure that the supply is set for the correct ac voltage to be used. If necessary, convert the line voltage to another by following the instructions under “Line Voltage Conversion”. Agilent Models 6010A, 6011A, 6012B and 6015A.
The offset pin on the standard power cable three-prong connector is the ground connection. If a two-contact receptacle is encountered, it must be replaced with a properly grounded three-contact receptacle in accordance with the National Electrical Code and any local codes and ordinances. The work should be done by a qualified electrician only. Note: To reduce noise pickup, it is good practice to keep the ac input lines separated from signal lines.

AC Line Impedance Check The power supply is designed for proper operation with line impedances typically found in ac power lines. However, if the supply is connected to an ac power line having a high impedance combined with line voltage near the minimum specified value, (e.g., 104 Vac for nominal 120 Vac), the unit will go out of regulation if it is asked to provide full rated output power.

Either positive or negative voltages can be obtained from the supply by grounding one of the output terminals. It is best to avoid grounding the output at any point other than the power supply output terminals to avoid noise problems caused by common-mode current flowing through the load leads to ground. Always use two wires to connect the load to the supply regardless of where or how the system is grounded. Never ground the system at more than one point.
circuits within the supply the power supply output drops to zero and the UNREGULATED indicator turns on. The power supply can be disabled by overvoltage, overtemperature, or by low or high ac line (mains) voltage. Overvoltage. If the voltage across the power supply output terminals rises above a preset level, possibly because of a hardware malfunction, the overvoltage protection (OVP) circuit will trip. If this occurs, the power supply will be disabled and the OV indicator turned on.
crosses the operating locus at point 1. Point 1 is on the part of the operating locus defined by the voltage setting, so the power supply operates in CV mode. Similarly, the line representing load resistance C, the lowest load resistance shown on the graph, crosses the operating locus at point 3. Point 3 is on the part of the operating locus defined by the current setting, so the power supply operates in CC mode.
Figure 3-5. Overrange Operation Constant Voltage Operation By pressing the DISPLAY SETTINGS pushbutton switch you can observe the setting (limits) of both the output voltage and the output current, rather than the actual output values. This you set the current limit when the power supply is operating in CV mode, or set the voltage limit while in CC mode, without having to disconnect or adjust the load. To set up the power supply for constant voltage operation: a.
Constant Current Operation To set up the power supply for constant current operation: a. With power supply turned off, connect the load to the output terminals. b. Turn on the power supply. Hold in DISPLAY OVP pushbutton switch and set OVP ADJUST potentiometer for the desired OVP trip voltage. In CC mode the voltage setting will limit output voltage under quiescent conditions, and the OVP circuit provides added protection against hardware faults. c.
Figure 3-6. Remote Voltage Sensing Because the sensing leads carry only a few milliamperes, the wires used for sensing can be much lighter than the load leads. Each sense lead should have no more than 0.2 ohms resistance. Use the resistivity columns in Table 3-2 to determine the minimum wire size for the length of sense leads being used. The sense leads should be a shielded, twisted pair to minimize the pickup of external noise.
Analog Programming These instruments can obtain their output voltage and current programming information from three distinct sources: 1) locally from the front panel, 2) remotely from an external isolated, voltage source or, 3) remotely from an external isolated, resistance. Mode switches B1, B2, .through B6, located on the rear of these products, enable the user to make these selections. The remote analog programming signals are connected to rear-panel screw-on terminals.
Note: If the programming terminals (VP to P) become open circuited during resistance programming, the output voltage will rise above the power supply rating. The supply will not be damaged if this occurs, but the overvoltage trip point should be properly adjusted to protect the user’s load. = Handle Figure 3-7. Resistance Programming of Output Voltage Constant Voltage Output, Voltage Control.
= Handle Figure 3-9. Optional Voltage Divider for Program Source Constant Current Output, Resistance Control. The setup shown in Figure 3-10 allows the output current to be varied by using an external resistor to program the supply. A programming resistor variable from 0 to 4000 ohms produces a proportional output current from zero to full scale. Note that fixed resistors may be connected in series and/or parallel with the variable programming resistor to set lower and/or upper output current limits.
Constant Current Output, Voltage Control. The setup shown in Figure 3-11 allows the output current to be varied by using an external voltage to program the supply. A voltage source variable from 0 to + 5 volts produces a proportional output current from zero to full scale. The static load on the programming voltage source is less than 5µA. A source resistance of less than 10k is necessary to avoid degradation of offset and drift specifications.
= Handle = Handle Figure 3-12. Auto-Parallel Operation Setting Voltage and Current. Program the slave unit's output voltage above the master's to avoid interference with masterunit CV control. The slave unit's mode switches disable the slave unit's digital current setting from having any effect in autoparallel operation. Program the master unit to the desired output voltage and 50% of total current. Verify that the slave is in CC operation.
Caution: When two supplies are operated in series, they should be programmed to the same voltage to prevent possible damage to the lower voltage supply during short circuit conditions. Contact the factory if this is not possible. = Handle = Handle Figure 3-13. Series Operation Monitor Signals Amplified and buffered voltage and current monitor output signals are available at the rear-panel terminal strip. These signals can be connected to remote meters to indicate output voltage and current.
A 100 VAC Input Power Option 100 General Information Description Option 100 is a modification of the power supply that involves changing the values of resistors located in the Overvoltage Protection and Power Limit Circuits. It also entails recalibrating the unit and changing the Front Panel. These changes allow the unit to operate at a lower line voltage of 90-105 Vac, while operating on the same line frequency of 48-63 Hz.
