ENERAL INFORMATION
1-2
This Operating Manual contains a description of the
Model 6034A System Power Supply, including specifications,
and installation and operating instructions. The 6034A User's
Guide, HP Part Number 08034-30003, contains basic operating
instructions for the 6034A along with programming examples
for
specific
Hewlett-Packard
computers
and
desktop
calculators.

SPECIFICATIONS
1-4
Instrument specifications are listed in Table 1-1. These
specifications are the performance standards or limits against
which the instrument is tested. Supplemental information is
also listed in Table 1-1, including typical, but non-warranted,
characteristics.

SAFETY CONSIDERATIONS
1-6
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 instruc¬
tions before operation. Refer to the Safety Summary page at
the beginning of this manual for a summary of general safety
information. Safety information for specific procedures is
located at appropriate places in this manual.

INSTRUMENT AND MANUAL
IDENTIFICATION
1-8
Hewlett-Packard power supplies are identified by a
two-part serial number. The first part is the serial number
prefix, a number-letter combination that denotes the date of a
significant design change and the country of manufacture.
The first two digits indicate the year (21 = 1981, 22=1982,
etc), the second two digits indicate the week, and "A"
designates the U.S.A. The second part of the serial number is
a different sequential number assigned to each power supply,
starting with 00101.
1-9
If the serial number on your instrument does not agree
with those on the title page of this manual, a yellow Manual
Changes sheet supplied with the manual defines the dif¬
ference between your instrument and the instrument de¬
scribed by this manual. The change sheet may also contain in¬
formation for correcting errors in the manual.

The Model 6034A System Power Supply is an HP-18
programmable unit that provides laboratory-grade perfor¬
mance with the high efficiency of switching regulation techni¬
ques. Autoranging allows the supply to provide at least 200
watts output power over a wide range of output voltage and
current combinations without the user having to select the
proper output range. Output voltage and current are con¬
tinuously indicated on individual meters. LED indicators show
the complete operating state of the unit. Front-panel controls
allow the user to set output voltage, current, and overvoltage
protection trip level. Overvoltage protection (OVP) protects
the user's load by quickly and automatically interrupting
energy transfer if a preset trip voltage is exceeded.
1-12
The 6G34A can be both a listener and a talker on the
HP-IB. Output voltage and current can be sent directly to the
6034A in volts and amps. Service can be requested asyn¬
chronously for each of six reasons, and the unit responds to a
serial poll by identifying the nature of any faults. Upon com¬
mand the 6034A will measure its output voltage or current and
put the value on the HP-IB.
1-13
The following parameters and features can be con¬
trolled via the HP-IB:
®
Output voltage
© Output current
Output power circuits off and on (Device Clear
also turns output circuits off)
®
Soft voltage limit (includes OVP trip level)
® Soft current limit
® Limit mode - CV or CC
® Time delay after output trigger or reset before
requesting service for limit mode or overrange
® Service request masks
® Trigger to implement latest mode, output
voltage and current, and OVP trip level
(Device Trigger also triggers unit)
® Trigger for output voltage or current
measurement
1-14
Output connections are made to rear-panel screw-on
terminals. Either the positive or negative output terminal may
be grounded, or the output may be floated up to ±240 Vdc
(including output voltage) from chassis ground. Output
voltage can be locally or remotely sensed, and the 6034A can
be operated in multiple-supply combinations for increased
output voltage or current capability.
1-15
The 8Q34A is considerably smaller, lighter, and more
efficient than older design supplies with similar output-power
capability. The unit is fan cooled and is packaged in a Hewlett-
Packard System II - compatible modular enclosure, which is
sturdy, attractive, and provides easy access for servicing.

OPTIONS
1-17
Options are standard factory modifications or ac¬
cessories that are delivered with the instrument. The following
options are available with the 6G34A. Note lower output power
