Agilent 6551A Data Sheet

This reliable series of 500 W dc
power supplies can be controlled
either from the front panel or via an
analog programming voltage. When
used in a test system, the fast up
and down programming helps
decrease test time. Quickly reacting
protection features, including fast
crowbar, CV/CC mode crossover and
over-voltage protection help protect
your valuable assemblies from dam­age. The linear topology produces
very low ripple and noise, which
allows you to make extremely accu­rate measurements of the devices
which you are testing.

Lab bench use is enhanced by the
fan speed control, which helps to
minimize the acoustic noise.

Supplemental Characteristics
for all model numbers

dc Floating Voltage: Output terminals can

be floated up to ±240 Vdc from chassis
ground

Remote Sensing: Up to half the rated
output voltage can be dropped in each
load lead. The drop in the load leads
subtracts from the voltage available for
the load.

Output Programming Response Time:

The rise and fall time (10/90% and
90/10%) of the output voltage is less
than 15 ms. The output voltage change
settles within 1 LSB (0.025% x rated
voltage) of final value in less than 60 ms.

Down Programming: An active down
programmer sinks approximately
20% of the rated output current

Modulation: (Analog programming of
output voltage and current)
Input signal: 0 to –5 V
Input impedance: 10 k Ohm nominal

ac Input: (ac input frequency 47 to 63 Hz)

Voltage 100 Vac 120 Vac 220 V ac 240 Vac
Current 12 A 10 A 5.7 A 5.3 A

Input Power: 1,380 VA, 1,100 W at full load;

120 W at no load
Regulatory Compliance: Listed to UL 1244;

certified to CSA556B; conforms to
IEC 61010-1.

Size: 425.5 mm W x 132.6 mm H x

497.8 mm D (16.75 in x 5.22 in x

19.6 in) See page 101 for more details
Weight: Net, 25 kg (54 lb); shipping,

28 kg (61 lb)

Your Requested Excerpt from the Agilent Power Products Catalog

The preceding page(s) are an excerpt from the 2002-2003 Power Products Catalog.
We hope that these pages supply the information that you currently need.
If you would like to have further information about the extensive selection of
Agilent dc power supplies, ac sources, and dc electronic loads, please visit

www.agilent.com/find/powerto print a copy of the complete Power Products

catalog, or to request that a copy be sent to you. You will also find a lot of other
useful information on this web site.

In the full Power Products Catalog, you will find that Agilent offers much more
than basic power generation. If you need basic, clean, power for your lab bench,
it’s there. But in each product category, we’ve also integrated the capabilities
that you need for a complete power solution, including extensive measurement
and analysis capabilities.

Please give us a call at your local Agilent Technologies sales office,
or call a regional office listed below, for assistance in choosing or using
Agilent power products.
