GENERAL
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of this
product may be impaired if it is used in a manner not specified in the operating instructions.
Any LEDs used in this product are Class 1 LEDs as per IEC 825-1.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is designed to
operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the specifications tables for
the ac mains voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety precautions are
taken. Note the instrument’s external markings described under "Safety Symbols".
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. The instrument
must be connected to the ac power supply mains through a three-conductor power cable, with the third wire firmly
connected to an electrical ground (safety ground) at the power outlet. For instruments designed to be hard-wired to the ac
power lines (supply mains), connect the protective earth terminal to a protective conductor before any other connection is
made. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause
a potential shock hazard that could result in personal injury. If the instrument is to be energized via an external
autotransformer for voltage reduction, be certain that the autotransformer common terminal is connected to the neutral
(earthed pole) of the ac power lines (supply mains).
ATTENTION: Un circuit de terre continu est essentiel en vue du fonctionnement sécuritaire de l’appareil. Ne
jamais mettre l’appareil en marche lorsque le conducteur de mise … la terre est d‚branch‚.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do
not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made
by qualified service personnel. Do not replace components with power cable connected. Under certain conditions,
dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power, discharge
circuits and remove external voltage sources before touching components.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is
present.
DO NOT EXCEED INPUT RATINGS
This instrument may be equipped with a line filter to reduce electromagnetic interference and must be connected to a
properly grounded receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of
those stated on the data plate may cause leakage currents in excess of 5.0 mA peak.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized
modifications to the instrument. Return the instrument to an Agilent Technologies Sales and Service Office for service and
repair to ensure that safety features are maintained.
Instruments that appear damaged or defective should be made inoperative and secured against unintended operation until
they can be repaired by qualified service personnel.

General Information
Introduction
This manual contains specifications, installation instructions, and operating instructions for DC Power Supply Models:
Agilent6010A, 6011A, 6012B, 6015A, 6023A and 6028A. Refer to "Related Documents" for other information concerning
these products.
Description
These power supplies are autoranging supplies.Autoranging allows the power supply to deliver full output power over a
higher voltage and current combination than would be possible with a rectangular output characteristic (see figure 1-1).
They use a 20k Hz pulse-width modulation circuit with power MOSFETs to provide the autoranging output characteristic
with laboratory performance.
Output voltage and current are continuously indicated on two 3 ½ digit displays. Front-panel controls allow the user to set
output voltage, current and Overvoltage Protection (OVP) trip levels. OVP protects the load by quickly and automatically
interrupting energy transfer if a preset voltage trip level is exceeded. Push button switches allow the display to alternately
show the programmed values of voltage and current or the overvoltage limit. LED indicators show the operating state of the
unit (CV, CC, Unregulated and Overvoltage).
All connections are made to rear-panel screw-on terminals.
Output voltage can be locally or remotely sensed.
A six-position MODE switch located on the rear panel is used to change from front panel control to remote voltage or
remote resistance control. See section 3 for a description of remote programming, remote sensing and several methods of
multiple supply operation.
Either the positive or negative output terminal may be grounded or the output may be floated (including output voltage) up
to ±240 Vdc on models 6011A, 6012B, 6023A and 6028A or ±550 Vdc on models 6010A and 6015A from chassis
ground.
The power supply is fan cooled and is packaged in an Agilent Technologies System II-compatible modular that provides
easy access for servicing. A thermostat shuts down the supply if an over-temperature condition occurs and resets
automatically.
Safety Considerations
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The instrument and this manual
should be reviewed for safety markings and instructions before operation. Refer to the Safety Summary page at the

Specifications
Specifications for the power supply fall into two major categories: performance specifications and supplemental
characteristics.
Performance specifications describe the power supply's warranted performance. All performance specifications are at the
rear output terminals with a resistive load. Specifications apply over the full operating temperature range of 25 +/- 5°C
unless otherwise specified range. The Service Manual has procedures for verifying the performance specifications.
Supplemental characteristics give typical but non-warranted performance parameters. Design or type testing determines
supplemental characteristics. They are useful in understanding the power supply’s operation when accessing applications for
the power supply.

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. Typically, at three inches from the supply, the electromagnetic field is less than 5 gauss.
Many CRT’s, such as those used in computer displays, are susceptible to magnetic fields much
lower than 5 gauss. Check susceptibility before mounting any display near the power supply.
Initial Inspection
Before shipment, this supply was inspected and found to be free of mechanical and electrical defects. As soon as the supply
is unpacked, inspect for any damage that may have occurred in transit. Save all packing materials until the inspection is
completed. If damage is found, file a claim with the carrier immediately. The Agilent Technologies Sales and Support office
should be notified as soon as possible.
Mechanical Check
This check should confirm that there are no broken knobs or connectors, that the cabinet and panel surfaces are free of dents
and scratches, and that the meter face and rear-panel plastic covers are not scratched or cracked.
Electrical Check
Section III contains an abbreviated check that can be used quickly to place the supply into operation. Refer to the inside
cover page of the manual for Certification and Warranty statements.
Preparation for Use
In order to be put into service, the power supply must be connected to an appropriate ac input power source. Also, the line
voltage for which the supply is set must be checked. Additional steps may include line voltage conversion and rack
mounting. Do not apply power to the supply before reading the “Input Power Requirements” section in this chapter.
Location and Cooling
The supply is fan cooled and must be installed with sufficient space in the rear and on sides for airflow. It should be used in
an area where the ambient temperature does not exceed + 50 °C (55 °C for models 6023Aand 6028A).
Caution: When mounting several units in an enclosed rack, care should be taken to insure there is sufficient airflow
through the enclosure. Failure to provide sufficient airflow may result in damage to the power supply or
other equipment in the enclosure.

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. Complete installation instructions are included with each rack mounting kit.
Support rails are also required for rack mounting. These are usually supplied with the system cabinet.
Input Power Requirements
This supply may be operated from a nominal 120 V, 220 V or 240 V single-phase ac power source (48-63 Hz). The input
voltage range and input current required for each of the nominal inputs is listed in Table 1-1. To operate from 100 Vac line,
Option 100 must be installed. This is a factory-installed option. A label on the rear panel indicates the nominal line voltage
for which the supply was set at the factory. If necessary, the user can convert the instrument from one line voltage option to
another by following the instructions in the “Line Voltage Option Conversion” section in this chapter.

Installation 19
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.
To connect input power, to the instrument proceed as follows:
a. Remove the AC filter assembly cover by unscrewing the four locating screws.
b. Insert the power cord through the strain relief clamp located on the cover.
c. Connect the wires to the terminal block in accordance with the prevailing color codes.
Green or green/yellow to the terminal labeled " ''
White or blue wire to the terminal labeled "N'' *
Black or brown wire to the terminal labeled ''L"
* In a 2-phase system, such as 208 in the USA, the second phase is connected to the "N'' terminal.
WARNING: For proper protection by the instrument circuit breaker, the wire connected to the "L’’terminal on
the instrument must be connected to the "L’’ side of the line (hot); the wire connected to the ’’N"
terminal must be connected to the "N" side of the line (neutral or common).
To protect operating personnel, the wire connected to the " ’’ terminal must be connected to
earth ground. In no event shall this instrument be operated without adequate ground connection.
d. Replace the cover, tighten all four screws and tighten the strain relief clamp. (All four screws must be tightened for unit
to meet RFI specifications.)
e. Connect the other end of the power cord to an appropriate power source.
Note:Connections to the ac power line must be made in accordance with applicable electrical codes. The
international color code for identifying mains supply conductors is green/yellow, blue, and brown for
earth, neutral, and line respectively. Corresponding USA/Canadian codes are green, white, and black.
Caution: Before applying power to the instrument, check to see that the rear-panel circuit breaker CB1 is on. The
breaker may trip due to rough handling during transit. If the breaker is found to be tripped at any other
time for unknown reasons, refer to the troubleshooting procedures in the Service Manual.
Agilent Models 6023A and 6028A.
The power supply is shipped from the factory with a power-cord plug appropriate for the user’s location. Figure 2-2
illustrates the standard configuration of power-cord plugs used by Agilent Technologies. With each drawing is the Agilent
Part Number for a replacement power cord equipped with a plug of that configuration. If a different power cord is required,
contact the nearest Agilent Technologies Sales and Service office.
To protect operating personnel, the National Electrical Manufacturers Association (NEMA) recommends that the instrument
panel and cabinet be grounded. This supply is equipped with a three-conductor power cable; the third conductor is the
ground conductor. When the cable is plugged into an appropriate receptacle the supply is grounded. In no event shall this
supply be operated without an adequate cabinet ground connection.

20 Installation
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.
Line Voltage Option Conversion
Caution: Conversion to or from 100 V operation requires replacement of internal components and calibration in
addition to the line voltage components, and is to be done only at the factory. Failure to configure and
calibrate the power supply properly may result in damage to the unit.
Agilent Models 6010A, 6011A, 6012B and 6015A.
Line voltage conversion is accomplished by adjusting three components: a two-section line select switch, and a line-voltage
jumper. To convert the supply from one line voltage option to another, proceed as follows:
WARNING: Some components and circuits are at ac line voltage even with the LINE switch off. To avoid
electric shock hazard, disconnect line cord and load, and wait two minutes before removing covers.
a. Remove the outside cover by removing the four screws that hold the carrying straps, spread the bottom of the cover
slightly and carefully slide the cover to the rear of the supply until it is clear. Next remove the top inside cover by
removing the nine screws, four on top, three on right side, and two on left side, which connect the top inside cover to
the supply chassis.
b. Remove the FET board to reach the line-voltage jumper (W1) terminals.
c. Use a small-blade screwdriver to set the two switch sections of S2 to match the pattern printed on the main board for
the nominal line voltage to be used. For example, to set switches for 120 V operation, move forward switch section so
that its white slot is toward front of supply and move rearward switch section so that its white slot is toward rear of the
instrument.
d. Set switch S1 to match the rearward section of S2, i.e., toward the rear for 100/120 V operation, toward the front for
220/240 V operation.
e. One end of W1 is soldered to the main board; the other end has a female quick-connect terminal that fits onto one of
two terminals soldered to the main board. For 100 V or 120 V operation, W1 must be connected to terminal J9; for 220
V or 240 V operation, W1 must be connected to terminal J10. Be certain that the jumper is firmly mated with the
connector on the main board. Do not grip jumper insulation with pliers; either grip the jumper wire by hand or grip the
jumper terminal with pliers.
f. Replace FET board, inside top cover and outside top cover. Mark the unit clearly with a tag or label indicating correct
line voltage to be used.
g. Change line label.
